| 1 | Mechanism of chain propagation for the synthesis of polyoxymethylene dimethyl ethers显示文摘Polyoxymethylene dimethyl ethers(PODE)were synthesized from the reaction of paraformaldehyde with dimethoxymethane(DMM)over different acid catalysts at different conditions.Products were found to follow the Schulz-Flory distribution law.The chain propagation proceeds through the insertion of an individual segment of CH2O one by one,while the simultaneous insertion of a few CH2O segments or their assembly is unlikely.Due to the restriction of this law,it is difficult to increase the selectivity to the desired products(e.g.,PODE3 4). | Yupei Zhao Zheng Xu Hui Chen Yuchuan Fu Jianyi Shen | 2013 | Journal of Energy Chemistry2013，22，6： | 36 |
| 2 | ^40Ar/^39Ar and Rb-Sr Ages of the Tiegelongnan Porphyry Cu-(Au)Deposit in the Bangong Co-Nujiang Metallogenic Belt of Tibet,China:Implication for Generation of Super-Large Deposit显示文摘The Tiegelongnan deposit is a newly discovered super-large porphyry-epithermal Cu-(Au) deposit in the western part of the Bangong Co-Nujiang metallogenic belt, Tibet(China). Field geology and geochronology indicate that the porphyry mineralization was closely related to the Early Cretaceous intermediate-felsic intrusions(ca. 123–120 Ma). Various epithermal ore and gangue mineral types were discovered in the middle-shallow part of the orebody, indicating the presence of epithermal mineralization at Tiegelongnan. Potassic, propylitic, phyllic and advanced argillic alteration zones were identified. ^(40)Ar/^(39)Ar dating of hydrothermal biotite(potassic zone), sericite(phyllic zone), and alunite(advanced argillic zone) in/around the ore-bearing granodiorite porphyry yielded 121.1±0.6 Ma(1σ), 120.8±0.7 Ma(1σ) and 117.9±1.6 Ma(1σ), respectively. Five hydrothermal mineralization stages were identified, of which the Stage IV pyrite was Rb-Sr dated to be 117.5±1.8 Ma(2σ), representing the end of epithermal mineralization. Field geology and geochronology suggest that both the epithermal and porphyry mineralization belong to the same magmatic-hydrothermal system. The Tiegelongnan super-large Cu-(Au) deposit may have undergone a prolonged magmatichydrothermal evolution, with the major mineralization event occurring at ca.120–117Ma. | LIN Bin CHEN Yuchuan TANG Juxing WANG Qin SONG Yang YANG Chao WANG Wenlei HE Wen ZHANG Lejun | 2017 | Acta Geologica Sinica(English Edition)2017，91，2： | 33 |

| 4 | Mineralization episode of porphyry copper deposits in the Jinshajiang-Red River mineralization belt: Re-Os dating显示文摘Re-Os isotopic dating for the molybdenites from the porphyry copper deposits of the Jinshajiang-Red River mineralization belt in Yunnan Province yields isochron ages of 33.9±1.1 Ma for the Machangqing deposit and 34.4±0.5 Ma for the Tongchang deposit. This result shows that both the Machangqing and the Tongchang porphyry Cu-Mo deposits from two different ore-fields formed simultaneously. This new data and the published Re-Os model ages of molybdenite (35.4 Ma, 35.9 Ma, 36.2 Ma) of the Yulong porphyry copper deposit in Tibet, which is located in the same Jinshajiang-Red River mineralization belt as the Machangqing deposit and the Tongchang deposit, suggest that these three Cenozoic porphyry copper deposits in the Jinshajiang-Red River mineralization belt were contemporary for their mineralization episode. That is to say, even their present locality is far away and nearly iso-distantly distributed, these three porphyry Cu(Mo) deposits belong to the same mineralization episode at the end of Eocene. | WANG Denghong, QU Wenjun, LI Zhiwei, YIN Hanlong4 & CHEN Yuchuan Institute of Mineral Resources, Chinese Academy of Geological Sciences, Beijing 100037, China National Center of Rock and Mineral Analysis, Chinese Academy of Geological Sciences, Beijing 100037, China Resource Assessment Center of Yunnan, Kunming 650011, China Institute of Geology and Geophysics, Chinese Academy of Sciences, Beijing 100101, China Chinese Academy of Geological Sciences, Beijing 100037, China | 2005 | Science China Earth Sciences2005，48，2： | 21 |

| 6 | Helium,Argon,and Xenon Isotopic Compositions of Ore-forming Fluids in Jinding-Baiyangping Polymetallic Deposits,Yunnan,Southwest China显示文摘The Jinding superlarge lead and zinc deposit has attracted the attention of geologists of the world and itsmetal logenesis has long been in dispute. This paper takes the Jinding deposit and the Baiyangping Cu-Ag-Co deposit which was recently found at about 30 km north of Jinding as one ore belt, and, based on researches on the helium, argon, and xenon isotopic compositions of primary inclusions in ore-forming solutions of the main stage, the authors have found that the 3He/4He ratio of the ore-forming fluid is 2.7×10-6 (varying from 0.19 to 1.97 Ra), the 4He/40Ar ratio (0.24-3.12) is close to the mantle characteristic ratio, and the xenon isotopic composition and evolution show characters of the mantle xenon. The above results reveal the characteristics of mantle source and crust-mantle fluid mixing (mantle helium reaching 32%) and the metallogenic contributions of the deep processes in the Jinding-Baiyangping ore belt. | XUE Chunji WANG Denghong CHEN Yuchuan YANG Jianmin YANG Weiguang | 2000 | Acta Geologica Sinica(English Edition)2000，74，3： | 17 |
| 7 | LA-ICP-MS Zircon U-Pb Dating of Intermediate-Acidic Intrusive Rocks and Molybdenite Re-Os Dating from the Bangpu Mo (Cu) Deposit, Tibet and its Geological Implication显示文摘The multi-stage intrusions of intermediate-acid magma occur in the Bangpu mining district, the petrogenic ages of which have been identified. The times and sequences of their emplacement have been collated and stipulated in detail in this paper by using the laser ablation-inductively coupled plasma-mass spectrometry (LA-ICP-MS) zircon U-Pb dating method. The ages of biotite monzogranite that were formed before mineralization in the southwest of this mining district are 70±1 Ma (mean square of weighted deviates (MSWD) =9.5, n=8) and 60.60±0.31 Ma (MSWD=3.8, n=16), which belong to the late Cretaceous-early Paleocene in age. That means, they are products of an early tectonicmagmatic event of the collision between the Indian and Asian continentals. The ages of ore-bearing monzogranite porphyry and ore-bearing diorite porphyrite are 16.23±0.19 Ma (MSWD=2.0, n=26) and 15.16±0.09 Ma (MSWD=3.9, n=5) separately, which belong to the middle Miocene in age; namely, they are products of the Gangdese post-collision extensional stage when crust-mantle materials melted and mixed as well as magmatic intrusion simultaneously occurred. Some zircons with ages of 203.6±2.2 Ma (MSWD=1.18, n=7) were captured in the ore-bearing diorite porphyrite, which shows that there had been tectono-magmatic events in the late Triassic-early Jurassic. Molybdenum (copper) ore-bodies produced in the monzogranite porphyry and copper (molybdenum) ore-bodies produced in the diorite porphyrite are the main ore types in this ore deposit. The model ages of Re-Os isotopic dating for the 11 molybdenite are 13.97-15.84 Ma, while isochron ages are 14.09±0.49 Ma (MSWD=26). The isochron ages of seven molybdenite from molybdenum (copper) ore with monzogranite porphyry type are 14.11±0.31 Ma (MSWD=5.2). There is great error in the isochron ages of four molybdenite from copper (molybdenum) ore with diorite porphyrite type, and their weighted average model ages of 14.6±1.2 Ma (MSWD=41), which generally represent the mineralization age. The results about the Re-Os isotopic dating of molybdenite in the ore of different types have limited exactly that, the minerlazation age of this ore deposits is about 14.09 Ma, which belongs to the middle Miocene mineralization. The Bangpu deposit has a uniform metallogenic dynamics background with the porphyry type and skarn-type deposits such as Jiama, Qulong and others. | WANG Liqiang CHEN Yuchuan TANG Juxing LU Pengrui LUO Maocheng WANG Huan CHEN Wei LENG Qiufeng | 2012 | Acta Geologica Sinica(English Edition)2012，86，5： | 13 |
| 8 | Petrogenesis and Tectonics of the Naruo Porphyry Cu(Au) Deposit Related Intrusion in the Duolong Area,Central Tibet显示文摘The Duolong area is the most important part of the Western Bangong-Nujiang Suture Zone porphyry Cu(Au) metallogenic belt, in Tibet, China. Here new detailed data are presented from LAICP-MS zircon U-Pb, whole-rock geochemical, and in-situ zircon Hf isotope analyses for igneous rocks in the large Naruo deposit(2.51 Mt of Cu and 82 t of Au) which is located ~2 km NE of the Duolong(Duobuza and Bolong) super-large gold-rich porphyry copper deposit. We integrated our results with previous research of other porphyry deposits in the Duolong area and have identified the timing, geodynamic setting, and petrogenesis of the mineralization-associated magmatic events. Based on the measurements, the Duolong area porphyry Cu(Au) deposit formations are associated with Early Cretaceous intermediate-felsic magmatism, which is consistent with U-Pb zircon ages of 120 Ma. All the main intrusive rocks in the ore-concentrated area have similar lithogeochemical characteristics; they show a relative enrichment in both light rare earth elements(LREEs) and large-ion lithophile elements(LILEs: Rb, Ba, K, etc.) and relative depletion in both heavy rare earth elements(HREEs) and high field strength elements(HFSEs: Nb, Ta, Zr, Hf, etc.). Moreover, the granite porphyry shows positive εHf(t) values between 1.38–7.37 suggesting that magmas were potentially derived from the partial melting of a depleted mantle wedge that had been metasomatized by subducted slab-derived fluids or melts. This paper points out that the formation of the porphyry-epithermal Cu(Au) deposit in the Duolong area was dominated by northward subduction of the Bangongco Tethys Plate beneath the Qiangtang block in the Early Cretaceous(124–114 Ma), when the subducted oceanic crust reached 50–70 km underground and generated different degrees of phase transformation, which lead to a melt produced by dehydration of amphibole minerals, a metasomatized mantle wedge, and induced mantle partial melting that produced the magma. Those deposits occurred in a continental arc tectonic setting, which is similar to the continental margin arc environment of the ocean-continent subduction setting of the Andes metallogenic belt in South America. | DING Shuai CHEN Yuchuan TANG Juxing ZHENG Wenbao LIN Bin YANG Chao | 2017 | Acta Geologica Sinica(English Edition)2017，91，2： | 9 |
| 9 | Synergistically Enhanced Mucoadhesive and Penetrable Polypeptide Nanogel for Efficient Drug Delivery to Orthotopic Bladder Cancer显示文摘Intravesical chemotherapy has been recommended after the gold standard of transurethral resection of the bladder tumor to prevent bladder cancer(BC)from local recurrence in the clinic.However,due to rapid urine excretion and barrier protection of the bladder wall,the clinical performances of chemotherapeutic drugs are severely compromised.In the present work,a smart positively charged disulfide-crosslinked nanogel of oligoarginine-poly(ethylene glycol)-poly(L-phenylalanine-co-L-cystine)(R_(9)-PEG-P(LP-co-LC))was prepared to prolong the retention period and enhance the penetration capability of chemotherapeutic agent toward the bladder wall.PEG significantly improved the aqueous dispersibility of the 10-hydroxycamptothecin(HCPT)-loaded R_(9)-PEG-P(LP-co-LC)(i.e.,R_(9)NG/HCPT)and enhanced the mucoadhesive capability by the nonspecific interaction between PEG chain and the bladder mucosa accompanied with the electrostatic interaction between the cationic R_(9)and negatively charged bladder mucosa.Besides,R_(9),as a cell-penetrating peptide,efficiently penetrated through the cell membrane and delivered carried cargo.The disulfide bond endowed the selective release behavior of HCPT triggered by the intracellular reductive microenvironment.As an advanced chemotherapeutic nanoformulation,the smart R_(9)NG/HCPT demonstrated superior cytotoxicity against human BC 5637 cells in vitro and remarkably enhanced tumor suppression activity toward orthotopic BC models of mouse and rat in vivo,indicating its great potential in the clinical intravesical BC chemotherapy. | Hui Guo Faping Li Heping Qiu Weiguo Xu Pengqiang Li Yuchuan Hou Jianxun Ding Xuesi Chen | 2020 | Research2020，，1： | 7 |

| 11 | Design and simulation of a compact ultra-wideband bandpass filter with a notched band using multiple-mode resonator technique显示文摘A novel, compact, and highly selective ultra-wideband(UWB) bandpass filter with a narrow notched band is presented. Apart from having a basic structure of a slotline multiple-mode resonator(MMR) and microstrip feed lines, this novel design introduces a cross-coupling between the input and output feed lines to enhance the filter selectivity. The design strictly follows the theory and verified by electromagnetic(EM) simulation and experiments. In addition, the narrow notched band is introduced by embedding a pair of split ring resonators(SRR) in order to reject any undesired existing radio signals that may interfere with the Federal Communications Commission(FCC)-defined UWB band. By changing the structural parameters of SRR, it can be easily tuned to any desired frequency. This filter can be integrated in UWB communication systems and efficiently improve the interference immunity from undesired signals such as wireless local area network(WLAN). | Yang Hong Chen Jing Yang Haolan Liu Yunlong Yang Yuchuan | 2016 | The Journal of China Universities of Posts and Telecommunications2016，23，1： | 6 |
| 12 | A Preliminary Review of Metallogenic Regularity of Silver Deposits in China显示文摘China has widely distributed silver deposits,and is rich in silver resources.Although silver deposits are mainly associated with Pb-Zn deposits,a number of independent silver deposits have also been discovered in recent years.Silver deposits include different types,such as submarine volcanism and continental volcanism related type,intrusion related type,and sedimentary related type.This study summarized the metallogenic regularity of China's silver deposits systematically based mainly on the data from 490 silver deposits.It is shown that submarine volcanic sedimentary type,continental volcanic or sub-volcanic type,skarn type,hydrothermal type(including vein type and stratabound type),sedimentary metamorphic type,sedimentary type and regolith type should be regarded as the most important prediction types of silver deposit.A total of 32 silver mineralization belts and 111 silver concentration areas have been delineated.The map of 'Spatial distribution of silver mineralization belts in China' and other series of maps finished in this study may provide a theoretical basis for the evaluation and prognosis of silver resources potential in China. | JIANG Biao ZHANG Daquan WANG Denghong WANG Chenghui CHEN Yuchuan BAI Ge | 2015 | Acta Geologica Sinica(English Edition)2015，89，3： | 5 |
| 13 | A Preliminary Review of Metallogenic Regularity of Copper Deposits in China显示文摘Copper resources in China are rich, but imported copper products are still required. Researches on metallogenic regularity of major types of copper deposits by geologists have involved in worldwide classification, significant copper belts, representative copper deposits, etc. Studies on metallogenic regularity of copper deposits in China also have made achievements with a long-term work. Combined with latest exploration advances obtained in recent ten years, this review aims to conclude the achievements of researches on copper metallogenic regularity in China. Based on data of 814 copper deposits and other ore(mineralized) occurrences, ten prediction types of copper deposits have been suggested. Porphyry and skarn copper ores are taken as the key targets. Porphyry copper deposits are the most important one which concentrate in Gangdese, Changdu-Sanjiang, Dexing and East Tianshan. The Cenozoic and Mesozoic are the major metallogenic epochs. Four main metallogenic epochs are been studied based on the copper ore geochronological data including Precambrian Era(Archean and Proterozoic), Paleozoic Era, Mesozoic Era and Cenozoic Era. Based on the study of metallogenic series of ore deposits in China, twenty-seven metallogenic series of copper deposits are proposed. This is suggested to deepen the study of metallogenic regularity of copper ore and provide the theory guide for copper resources prediction in China. | YING Lijuan CHEN Yuchuan WANG Denghong TANG Juxing CHEN Zhenghui WANG Chenghui | 2015 | Acta Geologica Sinica(English Edition)2015，89，1： | 5 |

| 15 | Cenozoic Mineralization in China,as a Key to Past Mineralization and a Clue to Future Prospecting显示文摘Many Cenozoic metal deposits have been found during the past decade. Among them, the Fuwan Ag deposit in Guangdong is the largest Ag deposit in China. Besides, the largest Cu deposit of China in Yulong, Tibet, the largest Pb-Zn deposit of China in Jinding, Yunnan, and the largest Au deposit of China in Jinguashi,Taiwan, were also formed in the Cenozoic. Why so many important 'present' deposits formed during such a short period of geological history is the key problem. The major reason is that different tectonic settings control different kinds of magmatic activity and mineralization at the same time. In southwestern China, porphyry-type Cu deposits such as Yulong were formed during the early stage of the Himalayan orogeny, sediment-hosted Pb-Zn deposits such as Jinding were formed within intermontane basins related to deep faults, and carbonatite-related deposits such as the Maoniuping REE deposit and alkalic magmatic rock-related deposits such as the Beiya Au deposit originated from the mantle source. | WANG Denghong CHEN Yuchuan XU Jue YANG Jianmin XUE Chunji YAN Shenghao | 2000 | Acta Geologica Sinica(English Edition)2000，74，3： | 4 |
| 16 | DICER1 regulates antibacterial function of epididymis by modulating transcription of p-defensins显示文摘DICER1 is a key enzyme responsible for the maturation of microRNAs. Recent evidences suggested that DICER1 and microRNAs expressed in epididymis were involved in the control of male fertility. However, the exact mechanism remains to be elucidated. Here, we created a mouse line by targeted disruption of Dicerl gene in the principal cells of distal caput epididymis. Our data indicated that a set of β-defensin genes were downregulated by DICER1 rather than by microRNAs. Moreover, DICER1 was significantly enriched in the promoter of β-defensin gene and controlled transcription. Besides, the antibacterial ability of the adult epididymis significantly declined upon Dicerl deletion both in vitro and in vivo. And a higher incidence of reproductive defect was observed in middle-aged Dicerl^-|- males. These results suggest that DICER1 plays an important role in transcription of β-defensin genes, which are associated with the natural antibacterial properties in a microRNA-independent manner, and further impacts the male fertility. | Chunhua Tang Minjie Ni Shengsong Xie Yao Zhang Chaobao Zhang Zimei Ni Chen Chu Ligang Wu Yuchuan Zhou Yonglian Zhang | 2019 | Journal of Molecular Cell Biology2019，11，5： | 3 |
| 17 | Clinical features and predictors of remission in children under the age of 7 years with Graves’disease显示文摘Importance:Graves’disease(GD)is rare in children under the age of 7 years.Children with this disease exhibit greater thyrotoxicity at diagnosis and require a longer course of medical therapy,compared with pubertal and postpubertal children and adults.Objective:To investigate the clinical features and identify predictors of remission in children under the age of 7 years with GD.Methods:This retrospective study included 77 children who were diagnosed with GD under the age of 7 years and were treated in the Department of Endocrinology,Beijing Children’s Hospital from 2010 to 2018.Clinical manifestations,laboratory data,and follow-up records were collected for all patients.Children who achieved remission of treatment with methimazole were compared with those who had persistent disease to identify which variables were associated with remission;multiple logistic regression and Cox regression analyses were used to evaluate interactions among predictive variables.Results:Sixty-three boys and 14 girls were included;the median age at diagnosis was 4.2 years(interquartile range:3.2-5.3 years).Forty-six(56.7%)patients had no family history of thyroid disease,17 patients had family history of thyroid disease and 14 patients with unknown family history.Of the 77 patients,18(23.4%)patients achieved remission of treatment with methimazole and 59 patients did not;moreover,51(66.2%)had Graves’ophthalmopathy.Univariate analyses revealed no significant differences between the remission group and non-remission group in terms of age at diagnosis,sex,initial goiter size,or initial thyroid hormone concentration.However,there were a trend of correlation between the initial level of thyroid peroxidase antibody(TPOAb)and remission status(univariate analysis OR 1.002,P=0.038;multivariate analysis OR 1.004,P=0.019).Similar results were observed in univariate analysis of the initial thyrotropin receptor antibody(TRAb)level,but this association was not significant in multivariate analysis.Cox regression analyses revealed that children with high TRAb level required longer duration of remission,compared with low TRAb level(OR 0.950,95%CI 0.904-0.997,P=0.037).Interpretation:Initial TRAb level was an independent predictor of remission outcome in young children under the age of 7 years with GD.Initial TRAb level may predict the likelihood of remission in patients with young-age-of-onset GD. | Yi Gu Xuejun Liang Ming Liu Di Wu Wenjing Li Bingyan Cao Yuchuan Li Chang Su Jiajia Chen Chunxiu Gong | 2020 | Pediatric Investigation2020，4，3： | 3 |
| 18 | Review of the Metallogenic Regularity of Magnesite Deposits in China显示文摘China has abundant reserves of magnesite, making it the world's leading source of this strategic mineral.Sparry magnesite is the main type of magnesite deposit, and is easy to exploit.It occurs mainly as the sedimentary-metamorphic type.Production is centred on eastern Liaoning Province, where a world-class large to super large magnesite ore processing and production facility has been developed.Hydrothermal metasomatic deposits, associated with ultramafic complexes and eluvial deposits produced by weathering, are two other important types found in China.The Western section of the Bangonghu-Nujiang metallogenic belt is an important target region for prospecting lake-sedimentary magnesite deposits.Based on a systematic analysis of material from 62 magnesite production areas, this study investigated the metallogeny of magnesite and delineated 13 magnesite metallogenic belts.Maps were produced showing metallogenic regularities in magnesite deposits, the metallogenic system of the magnesite deposits, and the distribution of the metallogenic belts of Chinese magnesite deposits.It provides a theoretical basis for forecasting the location of potential magnesite resources in China.Finally, it explores some key scientific issues, including the formation processes of ultra magnesite ore-concentrated areas, and their sources of magnesium. | ZHAO Zheng CUI Xiaolin WANG Denghong CHEN Yuchuan BAI Ge LI Jiankang LIU Xinxing | 2015 | Acta Geologica Sinica(English Edition)2015，89，5： | 3 |
| 19 | Time Sequence of Himalayan Endogenetic Mineralization on the East Side of the Qinghai-Tibet Plateau显示文摘Among the endogenetic deposits in the Sanjiang area and at the west margin of the Yangtze platform, Himalayan deposits are the most important and contribute a large proportion of the resources of superlarge deposits. Among the controlled resources of this region, 84% of copper resources, 67% of Pb-Zn, 31% of Ag, 77% of gold and 24% of tin come from Himalayan deposits on the east side of the Qinghai-Tibet plateau. Himalayan endogenetic mineralization shows a relatively complete sequence evolution in the Sanjiang area and on the west margin of the Yangtze platform. Mineralization is manifested by gold deposits related to K-rich lamprophyre, REE deposits related to alkalic complexes and Cu-Au-polymetallic deposits related to alkaline porphyry. Six sequences of mineralization evolution since 65 Ma B.P. in the Sanjiang area and on the west side of the Yangtze platform can be recognized. Himalayan endogenetic mineralization on the east side of the Qinghai-Tibet plateau reached its peak before the Oligo-cene, | LUO Junlie CHEN Yuchuan WANG Denghong | 2000 | Acta Geologica Sinica(English Edition)2000，74，3： | 2 |
| 20 | Glucose-derived hydrothermal carbons as energy storage booster for vanadium redox flow batteries显示文摘Fabricating of high performance electrodes by a sustainable and cost effective method is essential to the development of vanadium redox flow batteries(VRFBs).In this work,an effective strategy is proposed to deposit carbon nanoparticles on graphite felts by hydrothermal carbonization method.This in-situ method minimizes the drop off and aggregation of carbon nanoparticles during electrochemical testing.Such integration of felts and hydrothermal carbons(HTC)produces a new electrode that combines the outstanding electrical conductivity of felts with the effective redox active sites provided by the HTC coating layer.The presence of the amorphous carbon layers on the felts is found to be able to promote the mass/charge transfer,and create oxygenated/nitrogenated active sites and hence enhances wettability.Consequently,the most optimized electrode based on a rational approach delivers an impressive electrochemical performance toward VRFBs in wide range of current densities from 200 to 500 mAcm^-2.The voltage efficiency(VE)of GFs-HTC is much higher than the VEs of the pristine GFs,especially at high current densities.It exhibits a 4.18 times increase in discharge capacity over the pristine graphite felt respectively,at a high current density of 400 mAcm^-2.The enhanced performance is attributed to the abundant active sites from amorphous hydrothermal carbon,which facilitates the fast electrochemical kinetics of vanadium redox reactions.This work evidences that the glucose-derived hydrothermal carbons as energy storage booster hold great promise in practical VRFBs application. | Jiugen Qiu Baobing Huang Yuchuan Liu Dongyang Chen Zailai Xie | 2020 | Journal of Energy Chemistry2020，29，6： | 2 |
