| 1 | Theory, technology and prospects of conventional and unconventional natural gas显示文摘The development of natural gas in China has entered a golden and leap-forward stage, which is a necessary bridge to clean energy. This in-depth study on the status quo, theory, technology and prospect of natural gas development shows:(1) The global remaining proven recoverable reserves of natural gas are 186×1012 m3, and the reserves-production ratio is 52.4, indicating a solid resource base for long-term and rapid development.(2) Ten formation and distribution laws of conventional and unconventional natural gas reservoirs have been proposed. In terms of exploration geology, the theory of conventional 'monolithic' giant gas fields with different gas sources, and an unconventional gas accumulation theory with continuous distribution of 'sweet areas' in different lithologic reservoirs have been established; in terms of development geology, a development theory of conventional structural gas reservoirs is oriented to 'controlling water intrusion', while a development theory of unconventional gas is concentrated on man-made gas reservoirs.(3) With the geological resources(excluding hydrates) of 210×1012 m3 and the total proven rate of the resources less than 2% at present, the natural gas in China will see a constant increase in reserve and production; by 2030, the proven geological reserves of natural gas are expected to reach about(6 000-7 000)×108 m3, the production of conventional and unconventional natural gas each will reach about 1 000×108 m3, and the gas consumption will reach 5 500×108 m3. The dependence on imported natural gas may be 64% by 2030, and 70% by 2050.(4) Ten measures for future development of natural gas have been proposed, including strengthening exploration in large-scale resource areas, increasing the development benefits of unconventional gas, and enhancing the peak adjusting capacity of gas storage and scale construction of liquified natural gas. | ZOU Caineng YANG Zhi HE Dongbo WEI Yunsheng LI Jian JIA Ailin CHEN Jianjun ZHAO Qun LI Yilong LI Jun YANG Shen | 2018 | Petroleum Exploration and Development2018，45，4： | 4 |
| 2 | Smart ring resonator–based sensor for multicomponent chemical analysis via machine learning显示文摘We demonstrate a smart sensor for label-free multicomponent chemical analysis using a single label-free ring resonator to acquire the entire resonant spectrum of the mixture and a neural network model to predict the composition for multicomponent analysis. The smart sensor shows a high prediction accuracy with a low rootmean-squared error ranging only from 0.13 to 2.28 mg/m L. The predicted concentrations of each component in the testing dataset almost all fall within the 95% prediction bands. With its simple label-free detection strategy and high accuracy, the smart sensor promises great potential for multicomponent analysis applications in many fields. | ZHENYU LI HUI ZHANG BINH THI THANH NGUYEN SHAOBO LUO PATRICIA YANG LIU JUN ZOU YUZHI SHI HONG CAI ZHENCHUAN YANG YUFENG JIN YILONG HAO YI ZHANG AI-QUN LIU | 2021 | Photonics Research2021，9，2： | 3 |
| 3 | Detrital Zircon U-Pb Ages and Geochemistry of the Silurian to Permian Sedimentary Rocks in Central Inner Mongolia, China: Implications for Closure of the Paleo-Asian Ocean显示文摘The Solonker suture zone has long been considered to mark the location of the final disappearance of the PaleoAsian Ocean in the eastern Central Asian Orogenic Belt(CAOB). However, the time of final suturing is still controversial with two main different proposals of late Permian to early Triassic, and late Devonian. This study reports integrated wholerock geochemistry and LA-ICP-MS zircon U-Pb ages of sedimentary rocks from the Silurian Xuniwusu Formation, the Devonian Xilingol Complex and the Permian Zhesi Formation in the Hegenshan-Xilinhot-Linxi area in central Inner Mongolia, China. The depositional environment, provenance and tectonic setting of the Silurian-Devonian and the Permian sediments are compared to constrain the tectonic evolution of the Solonker suture zone and its neighboring zones. The protoliths of the silty slates from the Xuniwusu Formation in the Baolidao zone belong to wacke and were derived from felsic igneous rocks with steady-state weathering, poor sorting and compositional immaturity. The protoliths of metasedimentary rocks from the Xilingol Complex were wackes and litharenites and were sourced from predominantly felsic igneous rocks with variable weathering conditions and moderate sorting. The Xuniwusu Formation and Xilingol Complex samples both have two groups of detrital zircon that peak at ca. 0.9-1.0 Ga and ca. 420-440 Ma, with maximum deposition ages of late Silurian and middle Devonian age, respectively. Considering the ca. 484-383 Ma volcanic arc in the Baolidao zone, the Xuxiniwu Formation represents an oceanic trench sediment and is covered by the sedimentary rocks in the Xilingol Complex that represents a continental slope sediment in front of the arc. The middle Permian Zhesi Formation metasandstones were derived from predominantly felsic igneous rocks and are texturally immature with very low degrees of rounding and sorting, indicating short transport and rapid burial. The Zhesi Formation in the Hegenshan zone has a main zircon age peak of 302 Ma and a subordinate peak of 423 Ma and was deposited in a back-arc basin with an early marine transgression during extension and a late marine regression during contraction. The formation also crops out locally in the Baolidao zone with a main zircon age peak of 467 Ma and a minor peak of 359 Ma, and suggests it formed as a marine transgression sedimentary sequence in a restricted extensional basin and followed by a marine regressive event. Two obvious zircon age peaks of 444 Ma and 280 Ma in the Solonker zone and 435 Ma and 274 Ma in Ondor Sum are retrieved from the Zhesi Formation. This suggests as a result of the gradual closure of the Paleo-Asian Ocean a narrow ocean sedimentary environment with marine regressive sedimentary sequences occupied the Solonker and Ondor Sum zones during the middle Permian. A restricted ocean is suggested by the Permian strata in the Bainaimiao zone. Early Paleozoic subduction until ca. 381 Ma and renewed subduction during ca. 310-254 Ma accompanied by the opening and closure of a back-arc basin during ca. 298-269 Ma occurred in the northern accretionary zone. In contrast, the southern accretionary zone documented early Paleozoic subduction until ca. 400 Ma and a renewed subduction during ca. 298-246 Ma. The final closure of the Paleo-Asian ocean therefore lasted at least until the early Triassic and ended with the formation of the Solonker suture zone. | LI Yilong WANG Guoqing XIAO Wenjiao ZOU Jing ZHENG Jianping Fraukje MBROUWER | 2019 | Acta Geologica Sinica(English Edition)2019，93，5： | 2 |
| 4 | Randomized controlled study of a diagnosis and treatment plan for moderate coronavirus disease 2019 that integrates Traditional Chinese and Western Medicine显示文摘OBJECTIVE:To investigate the clinical efficacy and safety of a diagnosis and treatment plan for moderate coronavirus disease 2019(COVID-19)that integrates traditional Chinese(TCM)and western medicine.METHODS:One hundred twenty patients with moderate COVID-19 were randomized 1∶2 to the control group(n=40)and experimental group(n=80).Both groups received conventional western medicine treatment,and the experimental group also received TCM decoction.Over a 2-week period from diagnosis,we observed the time to clinical recovery(TTCR),rate of improvement on lung computed tomography(CT)imaging,time to defervescence,cough remission time,hospital discharge rate,average hospitalization stay,modified Medical Research Council(m MRC)scale score,clinical cure rate,laboratory findings,incidence of progression to severe or critical disease,and adverse events.RESULTS:Among 120 enrolled patients,108 completed the study.The baseline data did not differ between the experimental and control groups(all P>0.05).After treatment,the TTCR,rate of lung CT imaging improvement,time to defervescence,cough remission time,hospital discharge rate,average hospitalization stay(among discharged patients),m MRC scale score,clinical cure rate,and rates of normal values for laboratory findings were better in the experimental group than in the control group(P<0.05 or<0.01).The incidence of progression to severe or critical disease and the incidence of adverse events did not differ between the two groups(P>0.05).CONCLUSION:The diagnosis and treatment plan integrating Chinese and western medicine showed improved clinical efficacy compared with western medicine alone for patients with moderate COVID-19 and is worthy of clinical promotion and application. | XIA Wenguang ZHENG Chanjuan ZHANG Jixian HUANG Min LI Qinglin DUAN Can LI Zhengliang FAN Cunyu ZOU Yilong XU Bo YANG Fengwen LIU Qingquan | 2022 | Journal of Traditional Chinese Medicine2022，42，2： | 2 |
