| 1 | Geochemical features and genesis of the natural gas and bitumen in paleo-oil reservoirs of Nanpanjiang Basin, China显示文摘Bitumen from the Nanpanjiang Basin occurs mainly in the Middle Devonian and Upper Permian reef limestone paleo-oil reservoirs and reserves primarily in holes and fractures and secondarily in minor matrix pores and bio-cavities. N2 is the main component of the natural gas and is often associated with pyrobitumen in paleo-oil reservoirs. The present study shows that the bitumen in paleo-oil reservoirs was sourced from the Middle Devonian argillaceous source rock and belongs to pyrobitumen by crude oil cracking under high temperature and pressure. But the natural gas with high content of N2 is neither an oil-cracked gas nor a coal-formed gas generated from the Upper Permian Longtan Formation source rock, instead it is a kerogen-cracked gas generated at the late stage from the Middle Devonian argilla- ceous source rock. The crude oil in paleo-oil reservoirs completely cracked into pyrobitumen and methane gas by the agency of hugely thick Triassic deposits. After that, the abnormal high pressure of methane gas reservoirs was completely destroyed due to the erosion of 2000--4500-m-thick Triassic strata. But the kerogen-cracked gas with normal pressure was preserved under the relatively sealed condition and became the main body of the gas shows. | ZHAO MengJun ZHANG ShuiChang ZHAO Lin DA Jiang | 2007 | Science China Earth Sciences2007，50，5： | 11 |
| 2 | AFF3-DNA methylation interplay in maintaining the mono-allelic expression pattern of XIST in terminally differentiated cells显示文摘X chromosome inactivation and genomic imprinting are two classic epigenetic regulatory processes that cause mono-allelic gene expression.In female mammals,mono-allelic expression of the long non-coding RNA gene X-inactive specific transcript(XIST)is essential for initiation of X chromosome inactivation upon differentiation.We have previously demonstrated that the central factor of super elongation complex-like 3(SEC-L3),AFF3,is enriched at gamete differentially methylated regions(DMRs)of the imprinted loci and regulates the imprinted gene expression.Here,we found that AFF3 can also bind to the DMR downstream of the XIST promoter.Knockdown of AFF3 leads to de-repression of the inactive allele of X IST in terminally differentiated cells.In addition,the binding of AFF3 to the XIST DMR relies on DNA methylation and also regulates DNA methylation level at DMR region.However,the KAP1-H3K9 methylation machineries,which regulate the imprinted loci,might not play major roles in maintaining the mono-aUelic expression pattern of XIST in these cells.Thus,our results suggest that the differential mechanisms involved in the X IST DMR and gDMR regulation,which both require AFF3 and DNA methylation. | Yue Zhang Chao Wang Xiaoxu Liu Qian Yang Hongliang Ji Mengjun Yang Manman Xu Yunyan Zhou Wei Xie Zhuojuan Luo Chengqi Lin | 2019 | Journal of Molecular Cell Biology2019，11，9： | 3 |
| 3 | Life Prediction Based on Transient Dynamics Analysis of Van Semi-trailer with Air Suspension System显示文摘The early fatigue damage in the van-body of the semi-trailer is often caused by the unique mechanical characteristics and the dynamic impact of the loads.The traditional finite element method with static strength analysis cannot support the fatigue design of van-body;thus,the dynamics analysis should be adopted for the endurance performance.The accurate dynamics model to describe the transient impacts of all kinds of uneven road and the proper system transfer functions to calculate the load transfer effects from tire to van-body are two critical factors for transient dynamics analysis.In order to evaluate the dynamic performance,the dynamics model of the trailer with the air suspension is brought forward.Then the analysis method of the power spectral density (PSD) is set up to study the transient responses of the road dynamic impacts.The transient responses transferred from axles to van-body are calculated,such as dynamic stress,dynamic RMS acceleration,and dynamic load factors.Based on the above dynamic responses,the fatigue life of van-body is predicted with the finite element analysis (FEA) method.Applying the test parameters of the trailer with air suspension,the simulation system with Matlab/Simulink is constructed to describe the dynamic responses of the impacts of the tested PSD of the vehicle axles,and then the fatigue life is predicted with FEA method.The simulated results show that the vibration level of the van-body with air suspension is reduced and the fatigue life is improved.The real vehicle tests on different roads are carried out,and the test results validate the accuracy of the simulation system.The proposed fatigue life prediction method is effective for the virtual design of auto-body. | LI Liang SONG Jian HE Lin ZHANG Mengjun LI Hongzhi | 2011 | Chinese Journal of Mechanical Engineering2011，24，3： | 3 |
| 4 | The key stage and moment of coalbed gas reservior evolution in the Qinshui Basin,China显示文摘The evolution of coalbed gas reservoir is characterized by coalbed gas geochemistry and gas content. On the basis of burial history and thermal history, the forming process of coalbed gas reservoir and the gas accumulative history in the Qinshui Basin are discussed in this paper. The difference of the thermal history, geochemistry characteristic, and gas accumulative history between Yangcheng and Huozhou areas shows that the formation of coalbed gas reservoir in the Qinshui Basin is controlled by the geological process in the critical stage and the critical moment. The components and isotopes of coalbed methane are determined by the stage at which the coal maturation reaches its maximum rank. The coalbed methane accumulative history is related to the temperature and pressure of the coal burial history, because the coalbed gas is mainly in adsorptive state. It is stated that the gas content in the coal seam is controlled by the moment when the coal seam is uplifted to the shallowest position. | ZHAO Mengjun SONG Yan SU Xianbo LIU Shaobo QIN Shengfei HONG Feng LIN Xiaoying | 2005 | Chinese Science Bulletin2005，50，S1： | 2 |
