| 3 | Provably Secure General Aggregate Signcryption Scheme in the Random Oracle Model显示文摘To reduce the size of certificate chains and the ciphertext size in secure routing protocols, a General Aggregate Signcryption Scheme (GASC) is presented. In GASC, an identity-based signcryption algorithm and an aggregate signature algorithm are combined in a practical and secure manner to form the general aggregate signcryption scheme's schema and concept, and a new secure, efficiently general aggregate signcryption scheme, which allows the aggregation of n distinct signcryptions by n distinct users on n distinct messages, is proposed. First, the correction of the GASC scheme is analyzed. Then, we formally prove the security of GASC in the random oracle models IND-CCA2 and EUF-CMA under the DBDHP assumption and the DLP assumption, respectively. The results show that the GASC scheme is not only secure against any probabilistic polynomial-time IND-GASC-CCA2 and EUF-GASC-CMA adversary in the random oracle models but also efficient in pairing ê computations. In addition, the GASC scheme gives an effective remedy to the key escrow problem, which is an inherent issue in IBC by splitting the private key into two parts, and reduces the communication complexity by eliminating the interaction among the senders (signers) before the signcryption generation. | Qi Zhenghua Ren Xunyi Yang Geng | 2012 | China Communications2012，9，11： | 13 |

| 5 | A modified protocol with rituximab and intravenous immunoglobulin in emergent ABO-incompatible liver transplantation for acute liver failure显示文摘BACKGROUND: The established procedure for ABO-incompatible liver transplantation(ABO-I LT) was too complicated to be used in case of emergency. We developed a protocol consisting of rituximab and intravenous immunoglobulin(IVIG) for ABO-I LT in patients with acute liver failure(ALF).METHODS: The data from 101 patients who had undergone liver transplantation(LT) for ALF were retrospectively analyzed.The patients were divided into two groups: ABO-compatible liver transplantation group(ABO-C LT, n=66) and ABO-I LT group(n=35). All the patients in the ABO-I LT group received a single dose of rituximab(375 mg/m2) and IVIG(0.4 g/kg per day) at the beginning of the operation. IVIG was administered for 10 consecutive days after LT. Plasma exchange, splenectomy and graft local infusion were omitted in the protocol.Quadruple immunosuppressive therapy including basiliximab,corticosteroids, tacrolimus and mycophenolatemofetil was used to reinforce immunosuppression.RESULTS: The 3-year cumulative patient survival rates in the ABO-I LT and ABO-C LT groups were 83.1% and 86.3%,respectively(P>0.05), and the graft survival rates were 80.0%and 86.3%, respectively(P>0.05). Two patients(5.7%) suffered from antibody-mediated rejection in the ABO-I LT group.Other complications such as acute cellular rejection, biliary complication and infection displayed no significant differences between the two groups.CONCLUSIONS: The simplified treatment consisting of rituximab and IVIG prevented antibody-mediated rejection for LT of blood-type incompatible patients. With this treatment, the patients did not need plasma exchange, splenectomy and graft local infusion. This treatment was safe and efficient for LT of the patients with ALF. | Tian Shen Bing-Yi Lin Jun-Jun Jia Zhuo-Yi Wang Li Wang Qi Ling Lei Geng Sheng Yan Shu-Sen Zheng | 2014 | Hepatobiliary & Pancreatic Diseases International2014，13，4： | 11 |

| 7 | Daily variation characteristics of CO2 emission fluxes and contributions of environmental factors in semiarid grassland of Inner Mongolia, China显示文摘Fixed field experimental studies are carried out on daily variations of the undis- turbed community and soil respiration fluxes in different phenological phases of 2001―2002 in semiarid Aneurolepidium chinense steppe of Inner Mongolia, China using static black chamber method. Corresponding statistical analysis of the contributions of the water-heat factors (air temperature, ground temperature, surface soil water content) and ecological factors (above- ground biomass, underground biomass, litter biomass) to daily variation law of the undisturbed community and soil respiration fluxes as well as differences in daily respiration are also con- ducted. The results indicate that undisturbed community and soil respiration have apparent daily variation laws, daily variation patterns of respiration fluxes during different phenological phases are basically the same, and the variations of environmental factors only exert effect on CO2 emission intensities, while the effect on daily variation pattern of grassland CO2 emission fluxes is relatively small. The daily total respiration of the undisturbed community in different phenological phases ranges from 1.34―10.13 g·m?2; soil daily total respiration ranges from 0.98―5.17 g·m?2; both daily variations of undisturbed community and soil respiration fluxes are significantly corre- lated (p < 0.05) or extremely significantly correlated (p < 0.01) with air temperatures and ground surface temperatures, but the correlativity with the soil temperature at 5 and 10 cm depths is relatively weak; multiple regression analysis indicates that about 80% of the difference in daily respiration of the undisturbed community among different phenological phases is induced by the variation of the aboveground biomass, while the variations of the remaining factors can jointly explain around 20% of the daily respiration variations of the whole grassland ecosystem; about 83% of the soil daily respiration variation of the different phenological phases is caused by 0―20 cm underground biomass. Besides, surface soil water content is also an important environmental factor affecting soil daily respiration variations of the Aneurolepidium chinense steppe, but its partial correlation coefficient with soil daily respiration amount does not reach the significance level of 0.05. | QI Yuchun DONG Yunshe LIU Jiyuan GENG Yuanbo LI Mingfeng YANG Xiaohong LIU Lixin | 2005 | Science China Earth Sciences2005，48，7： | 11 |
| 8 | Estimating survival benefit of adjuvant therapy based on a Bayesian network prediction model in curatively resected advanced gallbladder adenocarcinoma显示文摘BACKGROUND The factors affecting the prognosis and role of adjuvant therapy in advanced gallbladder carcinoma(GBC)after curative resection remain unclear.AIM To provide a survival prediction model to patients with GBC as well as to identify the role of adjuvant therapy.METHODS Patients with curatively resected advanced gallbladder adenocarcinoma(T3 and T4)were selected from the Surveillance,Epidemiology,and End Results database between 2004 and 2015.A survival prediction model based on Bayesian network(BN)was constructed using the tree-augmented na?ve Bayes algorithm,and composite importance measures were applied to rank the influence of factors on survival.The dataset was divided into a training dataset to establish the BN model and a testing dataset to test the model randomly at a ratio of 7:3.The confusion matrix and receiver operating characteristic curve were used to evaluate the model accuracy.RESULTS A total of 818 patients met the inclusion criteria.The median survival time was 9.0 mo.The accuracy of BN model was 69.67%,and the area under the curve value for the testing dataset was 77.72%.Adjuvant radiation,adjuvant chemotherapy(CTx),T stage,scope of regional lymph node surgery,and radiation sequence were ranked as the top five prognostic factors.A survival prediction table was established based on T stage,N stage,adjuvant radiotherapy(XRT),and CTx.The distribution of the survival time(>9.0 mo)was affected by different treatments with the order of adjuvant chemoradiotherapy(cXRT)>adjuvant radiation>adjuvant chemotherapy>surgery alone.For patients with node-positive disease,the larger benefit predicted by the model is adjuvant chemoradiotherapy.The survival analysis showed that there was a significant difference among the different adjuvant therapy groups(log rank,surgery alone vs CTx,P<0.001;surgery alone vs XRT,P=0.014;surgery alone vs cXRT,P<0.001).CONCLUSION The BN-based survival prediction model can be used as a decision-making support tool for advanced GBC patients.Adjuvant chemoradiotherapy is expected to improve the survival significantly for patients with node-positive disease. | Zhi-Min Geng Zhi-Qiang Cai Zhen Zhang Zhao-Hui Tang Feng Xue Chen Chen Dong Zhang Qi Li Rui Zhang Wen-Zhi Li Lin Wang Shu-Bin Si | 2019 | World Journal of Gastroenterology2019，25，37： | 9 |
| 9 | Prevention and control of HIV/AIDS in China:lessons from the past three decades显示文摘In the past 37 years,human immunodeficiency virus/acquired immunodeficiency syndrome(HIV/AIDS)has undergone various major transmission routes in China,with the world most complex co-circulating HIV-1 subtypes,even the prevalence is still low.In response to the first epidemic outbreak of HIV in injecting drug users and the second one by illegal commercial blood collection,China issued the Anti-Drug Law and launched the Blood Donation Act and nationwide nucleic acid testing,which has avoided 98,232 to 211,200 estimated infections and almost ended the blood product-related infection.China has been providing free antiretroviral therapy(ART)since 2003,which covered>80%of the identified patients and achieved a viral suppression rate of 91%.To bend the curve of increasing the disease burden of HIV and finally end the epidemic,China should consider constraining HIV spread through sexual transmission,narrowing the gaps in identifying HIV cases,and the long-term effectiveness and safety of ART in the future. | Jun-Jie Xu Meng-Jie Han Yong-Jun Jiang Hai-Bo Ding Xi Li Xiao-Xu Han Fan Lv Qing-Feng Chen Zi-Ning Zhang Hua-Lu Cui Wen-Qing Geng Jing Zhang Qi Wang Jing Kang Xiao-Lin Li Hong Sun Ya-Jing Fu Ming-Hui An Qing-Hai Hu Zhen-Xing Chu Ying-Jie Liu Hong Shang | 2021 | Chinese Medical Journal2021，，23： | 9 |

| 11 | Pancreatogastrostomy vs pancreatojejunostomy after pancreaticoduodenectomy: An updated meta-analysis of RCTs and our experience显示文摘BACKGROUND Pancreatoduodenectomy(PD)is one of the most important operations in hepatobiliary and pancreatic surgery.AIM To evaluate the advantages and disadvantages of pancreaticojejunostomy(PJ)and pancreaticogastrostomy(PG).METHODS This meta-analysis was performed using Review Manager 5.3.All clinical randomized controlled trials,in which patients underwent PD with pancreaticodigestive tract reconstruction via PJ or PG,were included.RESULTS The search of PubMed,Wanfang Data,EMBASE,and the Cochrane Library provided 125 citations.After further analysis,11 trials were included from nine counties.In all,909 patients underwent PG and 856 underwent PJ.Meta-analysis showed that pancreatic fistula(PF)was a significantly lower morbidity in the PG group than in the PJ group(odds ratio[OR]=0.67,95%confidence interval[CI]:0.53-0.86,P=0.002);however,grades B and C PF was not significantly different between the two groups(OR=0.61,95%CI:0.34-1.09,P=0.09).Postoperative hemorrhage showed a significantly lower morbidity in the PJ group than in the PG group(OR=1.47,95%CI:1.05-2.06,P=0.03).Delayed gastric emptying was not significantly different between the two groups(OR=1.09,95%CI:0.83-1.41,P=0.54).CONCLUSION There is no difference in the incidence of grades B and C PF between the two groups.However,postoperative bleeding is significantly higher in PG than in PJ.Binding PJ or binding PG is a safe and secure technique according to our decades of experience. | Yun Jin Yang-Yang Feng Xiao-Gang Qi Geng Hao Yuan-Quan Yu Jiang-Tao Li Shu-You Peng | 2019 | World Journal of Gastrointestinal Surgery2019，11，7： | 7 |
| 12 | Oxyvanite V3O5:A new intercalation-type anode for lithium-ion battery显示文摘In the present study,V3O5 microcrystals that synthesized via vacuum calcination are employed as anodes for lithium-ion batteries(LIBs)for the first time.Despite the widely observed sluggish reaction kinetics and poor cycling stability in most microsized transition metal oxides,the V3O5 microcrystals exhibit excellent rate capability(specific capacities of 144 and 125 mAh g^−1 are achieved at extremely high current densities of 20 and 50 A g^−1,respectively)and long-term cycling performance(specific capacity of 117 mAh g^−1 is sustained over 2000 cycles at 50 A g^−1).It is ascribed to the three-dimensional open-framework structure of the V3O5 microcrystals as a major factor in dictating the fast reaction kinetics(lithium diffusion coefficient:~10−9 cm^2 s^−1).In addition,significant insight into the reaction mechanism of the V3O5 microcrystals in concomitant its phase evolution are obtained from ex-situ XRD study,revealing that the V3O5 microcrystals undergo intercalation reaction with insignificant structural change in response to lithiation/delithiation. | Dong Chen Huiteng Tan Xianhong Rui Qi Zhang Yuezhan Feng Hongbo Geng Chengchao Li Shaoming Huang Yan Yu | 2019 | InfoMat2019，1，2： | 6 |
| 13 | Expression of SNC73, a transcript of the immunoglobulin α-1 gene, in human epithelial carcinomas显示文摘AIM: To investigate the expression of SNC73, a trans- cript of the immunoglobulin α-1 gene (IgA1-H chain), in human epithelia-derived tumor cells. METHODS: Total RNAs and cell lysates were prepared from five different human epithelial cell lines derived from lung, stomach, liver, skin, and breast, respectively. RT-PCR and immunoblot analysis of these five cell lines were done. Both RT-PCR and immunochemistry were used to detect the expression of SNC73 in these cell lines. We also examined the expression of SNC73 in normal epithelial cells of colon mucosa by in situ hybridization. RT-PCR and immunoblot analysis were used to determine whether the recombination activating gene1/2 (RAG1 and RAG2) is present. The expression of three immunoglobulin transcription factors, EBF, E2A and Pax5, and the heavy chain of IgA1 and two types of light chains of immunoglobulin (κ and λ) in the aforementioned cell lines were analyzed by RT-PCR and immunochemistry, respectively. All the RT-PCR products were analyzed by sequencing. RESULTS: The results of RT-PCR and immunochemistry showed that both mRNA and protein of SNC73 were expressed in five human epithelia-derived cancer cell lines. These data were further confirmed in the normal epithelial cells of colon mucosa by in situ hybridization. Also, the heavy chain of IgA1 and κ light chain were detected in these cells, but no λ light chain was obse- rved. Both RAG1 and RAG2 were expressed in these human epithelia-derived cancer cell lines and the sequence was identical to that expressed in pre-B and pre-T cells. In addition to RAG1 and RAG2, the mRNA in one of the immunoglobulin transcription factors, EBF, was also detected in these cell lines, and Pax5 was onlyexpressed in SW480 cells, but no expression of E2A was observed in all the five cell lines. CONCLUSION: Immunoglobulin A1 is originally expressed and V(D)J recombination machine is also present in non-lymphoid cells, suggesting that V(D)J recombination machine mediates the assembly of immunoglobulin A1 in non-lymphoid cells as in pre- lymphocytes. | Li-Yi Geng Zheng-Zhen Shi Qi Dong Xin-Han Cai Yan-Ming Zhang Wei Cao Jia-Ping Peng Yong-Ming Fang Lei Zheng Shu Zheng | 2007 | World Journal of Gastroenterology2007，13，16： | 6 |
| 14 | XELOX doublet regimen versus EOX triplet regimen as first-line treatment for advanced gastric cancer:An open-labeled,multicenter,randomized,prospective phase III trial(EXELOX)显示文摘Background:There is no consensus on whether triplet regimen is better than doublet regimen in the first-line treatment of advanced gastric cancer(AGC).We aimed to compare the efficacy and safety of oxaliplatin plus capecitabine(XELOX)and epirubicin,oxaliplatin,plus capecitabine(EOX)regimens in treating AGC.Methods:This phase III trial enrolled previously untreated patients with AGC whowere randomly assigned to receive the XELOXor EOXregimen.The primary endpoint was non-inferiority in progression-free survival(PFS)for XELOX as compared with EOX on an intention-to-treat basis.Results:Between April 10,2015 andAugust 20,2020,448AGCpatientswere randomized to receive XELOX(n=222)or EOX(n=226).The median PFS(mPFS)was 5.0 months(95%confidence interval[CI]=4.5-6.0 months)in the XELOX arm and 5.5 months(95%CI=5.0-6.0 months)in the EOX arm(hazard ratio[HR]=0.989,95%CI=0.812-1.203;P_(non-inferiority)=0.003).There was no significant difference inmedian overall survival(mOS)(12.0 vs.12.0months,P=0.384)or objective response rate(37.4%vs.45.1%,P=0.291)between the two groups.In patients with poorly differentiated adenocarcinoma and liver metastasis,the EOX arm had a significantly longer mOS(P=0.021)and a trend of longer mPFS(P=0.073)than the XELOX arm.The rate of grade 3/4 adverse events(AEs)was 42.2%(90/213)in the XELOX arm and 72.5%(156/215)in the EOX arm(P=0.001).The global health-related quality of life(QoL)score was significantly higher in the XELOX arm than in the EOX arm during chemotherapy.Conclusions:This non-inferiority trial demonstrated that the doublet regimen was as effective as the triplet regimen and had a better safety profile and QoL as a first-line treatment for AGC patients.However,the triplet regimen might have a survival advantage in patients with poorly differentiated adenocarcinoma and liver metastasis. | Xiao-Dong Zhu Ming-Zhu Huang Yu-Sheng Wang Wan-Jing Feng Zhi-Yu Chen Yi-Fu He Xiao-Wei Zhang Xin Liu Chen-Chen Wang Wen Zhang Jie-Er Ying Jun Wu Lei Yang Yan-Ru Qin Jian-Feng Luo Xiao-Ying Zhao Wen-Hua Li Zhe Zhang Li-Xin Qiu Qi-Rong Geng Jian-Ling Zou Jie-Yun Zhang Hong Zheng Xue-Feng Song Shu-Sheng Wu Cheng-Yan Zhang Zhe Gong Qin-Qin Liu Xiao-Feng Wang Qi Xu Qi Wang Jian-Mei Ji Jian Zhao Wei-Jian Guo | 2022 | Cancer Communications2022，42，4： | 6 |
| 15 | Emission characteristics of carbon dioxide in the semiarid Stipa grandis steppe in Inner Mongolia, China显示文摘Using the static opaque chamber method, the soil respiration rates (SR ) were measured through the continuous experiments in situ in semiarid Stipa gra ndis steppe in Xilin River Basin of Inner Mongolia, China from June 2001 to June 2003, in parallel, the difference between the SR and the ecosystem respiration rates (TER) were compared. The results indicated that the seasonal variations of the SR and TER were obvious with higher emissions in growing season and a relat ively low efflux level in non-growing season, furthermore, the negative effluxes were found in the observation site in winter; the annual CO2 efflux of total ec osystem ranged from 160.5 gC/(m2·a) to 162.8 gC/(m2·a) and that of soil ranged from 118.7 gC/(m2·a) to 152.3 gC/(m2·a). The annual SR accounted for about 74.0% to 93.5% of the annual TER, but the results of Analysis of Var iance (ANOVA) indicated that the difference between the annual average TER and S R did not reach the significance level of 0.05. The TER was under similar enviro nmental controls as SR, in growing seasons of drought years, the variations of s oil moisture at 0—10 cm and 10—20 cm depth could account for 79.1%—95.6% of t he changes of the SR and TER, but in non-growing season, more than 75% of the va riations of the SR and TER could be explained by the changes of the ground tempe rature of soil surface layers. | LIU Xing-ren QI Yu-chun LIU Ji-yuan Manfred Domroes LIU Li-xin GENG Yuan-bo YANG Xiao-hong LI Ming-feng | 2006 | Journal of Environmental Sciences2006，18，3： | 5 |

| 17 | Geospatial Service Web:towards integrated cyberinfrastructure for GIScience显示文摘A geospatial cyberinfrastructure is needed to support advanced GIScience research and education activities.However,the heterogeneous and distributed nature of geospatial resources creates enormous obstacles for building a unified and interoperable geospatial cyberinfrastructure.In this paper,we propose the Geospatial Service Web(GSW)to underpin the development of a future geospatial cyberinfrastructure.The GSW excels over the traditional spatial data infrastructure by providing a highly intelligent geospatial middleware to integrate various geospatial resources through the Internet based on interoperable Web service technologies.The development of the GSW focuses on the establishment of a platform where data,information,and knowledge can be shared and exchanged in an interoperable manner.Theoretically,we describe the conceptual framework and research challenges for GSW,and then introduce our recent research toward building a GSW.A research agenda for building a GSW is also presented in the paper. | GONG Jianya WU Huayi ZHANG Tong GUI Zhipeng LI Zhenlong YOU Lan SHEN Shengyu ZHENG Jie GENG Jing QI Kunlun YANG Wenjing LI Zhenqiang YU Jingmin | 2012 | Geo-Spatial Information Science2012，15，2： | 5 |
| 18 | Liquid biopsy for esophageal cancer: Is detection of circulating cell-free DNA as a biomarker feasible?显示文摘Esophageal cancer(EC)is a common cancer and is histopathologically classified into esophageal squamous cell carcinoma and esophageal adenocarcinoma.EC is a worldwide public health issue because of late diagnosis and lack of effective therapy.In contrast to standard tumor biopsies,liquid biopsies are emerging as a tool which is minimally invasive that can complement or even substitute more classical approaches.Specifically,cell-free DNA(cfDNA)has shown promise in cancer-related clinical applications.Indeed,cfDNA has been shown to be an effective circulating biomarker for non-invasive cancer diagnosis and monitoring of cancer patients.Although the clinical application of cfDNA has been reported on other cancers,few studies have evaluated its use in EC.Here,we review this relevant literature and discuss limitations and advantages of its application in the diagnosis and monitoring of EC. | Zuyang Yuan Xinfeng Wang Xiao Geng Yin Li Juwei Mu Fengwei Tan Qi Xue Shugeng Gao Jie He | 2021 | Cancer Communications2021，41，1： | 4 |
| 19 | Stability Analysis on Rotor Systems Supported by Self-acting Tilting-pad Gas Bearings with Frequency Effects显示文摘The recent research on stability of gas bearing-rotor systems still mostly adopts the same method as in oil-lubricated bearing-rotor systems.The dynamic coefficients of gas bearings in the case that the perturbation frequencies are same as the rotating speed are used to carry out the stability analysis of rotor systems.This method does not contact the frequency characteristics of dynamic stiffness and damping coefficients of gas bearings with the dynamical behaviors of rotor systems.Furthermore,the effects of perturbation frequencies on the stability of systems are not taken into account.In this paper,the dynamic stiffness and damping coefficients of tilting-pad gas bearings are calculated by the partial derivative method.On the base of solution of dynamic coefficients,two computational models are produced for stability analysis on rotor systems supported by tilting-pad gas bearings according to whether the degrees of the freedom of pads tilting motions are included in the equations of motion or not.In the condition of considering the frequency effects of dynamic coefficients of tilting-pad gas bearings,the corresponding eigenvalues of the rigid and first five vibration modes of the system with the working speeds of 8-30 kr/min are computed through iteratively solving the equations of motion of rotor-system by using two computational models,respectively.According to the obtained eigenvalues,the stability of rotor system is analyzed.The results indicate that the eigenvalues and the stability of rotor system obtained by these two computational models are well agreement each other.They all can more accurately analyze the stability of rotor systems supported by tilting-pad gas bearings.This research has important meaning for perfecting the stability analysis method of rotor systems supported by gas bearings. | YANG Lihua QI Shemiao GENG Haipeng YU Lie | 2011 | Chinese Journal of Mechanical Engineering2011，24，3： | 4 |
| 20 | First experimental constraints on WIMP couplings in the effective field theory framework from CDEX显示文摘We present weakly interacting massive particles(WIMPs) search results performed using two approaches of effective field theory from the China Dark Matter Experiment(CDEX), based on the data from both CDEX-1B and CDEX-10 stages. In the nonrelativistic effective field theory approach, both time-integrated and annual modulation analyses were used to set new limits for the coupling of WIMP-nucleon effective operators at 90% confidence level(C.L.) and improve over the current bounds in the low mχregion. In the chiral effective field theory approach, data from CDEX-10 were used to set an upper limit on WIMP-pion coupling at 90% C.L. We for the first time extended the limit to the m_(χ)<6 GeV/c^(2) region. | Yi Wang Zhi Zeng Qian Yue LiTao Yang KeJun Kang YuanJing Li Mehment Agartioglu HaiPeng An JianPing Chang JingHan Chen YunHua Chen JianPing Cheng Cheng Yi Chiang WenHan Dai Zhi Deng ChangHao Fang XinPing Geng Hui Gong QiuJu Guo XuYuan Guo HongJian He Li He ShengMing He JinWei Hu TuChen Huang HanXiong Huang HaiTao Jia LiPing Jia Xi Jiang HauBin Li JianMin Li Jin Li MingXuan Li RenMingJie Li Xia Li YuLan Li Bin Liao FongKay Lin ShinTed Lin ShuKui Liu YanDong Liu Yu Liu YuanYuan Liu ZhongZhi Liu Hao Ma YuCai Mao QiYuan Nie JinHua Ning Hui Pan NingChun Qi Jie Ren XiChao Ruan ChangSong Shang Vivek Sharma Ze She Lakhwinder Singh Monoj Kumar Singh TianXi Sun ChangJian Tang WeiYou Tang Yang Tian GuangFu Wang Li Wang Qing Wang Yu Chen Wang YunXiang Wang Zhen Wang Henry Tsz-King Wong ShiYong Wu YuCheng Wu HaoYang Xing Yin Xu Tao Xue YuLu Yan Nan Yi ChunXu Yu HaiJun Yu JianFeng Yue Ming Zeng BingTao Zhang Lei Zhang FengShou Zhang ZhenYu Zhang KangKang Zhao MingGang Zhao JiFang Zhou ZuYing Zhou JingJun Zhu | 2021 | Science China(Physics,Mechanics & Astronomy)2021，64，8： | 3 |
