1Progress in the biological function of alpha-enolase显示文摘Alpha-enolase(ENO1), also known as 2-phospho-D-glycerate hydrolase, is a metalloenzyme that catalyzes the conversion of 2-phosphoglyceric acid to phosphoenolpyruvic acid in the glycolytic pathway. It is a multifunctional glycolytic enzyme involved in cellular stress, bacterial and fungal infections, autoantigen activities, the occurrence and metastasis of cancer, parasitic infections, and the growth, development and reproduction of organisms. This article mainly reviews the basic characteristics and biological functions of ENO1.Hong Ji Jianfa Wang Jingru Guo Yue Li Shuai Lian Wenjin Guo Huanmin Yang Fanzhi Kong Li Zhen Li Guo Yanzhi Liu 2016Animal Nutrition2016,,1:9
2Early warning for geo-hazards based on the weather condition in China显示文摘According to national early warning practice for geo-hazards from 2003 to 2005,it is systematically concluded that the basic characteristics of geo-hazards,early warning method and forecast result based on the geological maps of China in a scale 1∶6 000 000.With the contrast of different characters between sustained rainfall and typhoon rainfall inducing geo-hazards,the disaster reduction result and some problems are preliminarily analyzed.Some basic recognition is that early warning to geo-hazards is feasible,national scale forecast is only to call attention,but can't immediately be used to disaster reduction decision-making.And,the future direction is to build a united disaster reduction framework of early warning system including national,provincial and county levels based on weather factors in different scale of area.Chuanzheng LIU Yanhui LIU Mingsheng WEN Can TANG Tiefeng LI Jianfa LIAN 2006Global Geology2006,9,2:9
3Depositional architecture of the late Ordovician drowned carbonate platform margin and its responses to sea-level fluctuation in the northern slope of the Tazhong region, Tarim Basin显示文摘The Tazhong Uplift of the late Ordovician is a drowned rimmed carbonate platform. The carbonate rock of the late Ordovician Lianglitage Formation in the northern slope of the Tazhong region is one of the significant petroliferous intervals. Based on petrofacies, depositional cycles, natural gammaray spectrometry and carbon/oxygen isotope data from the Lianglitage Formation, one 2nd-order, three 3rd-order and several 4th-order sequences have been recognized, and the late Ordovician relative sealevel fluctuation curve has been established. The sequences O 3 l-1 and O 3 l-2 on the platform are composed of highstand and transgressive systems tracts, but lack the lowstand systems tract. The sequence O 3 l-3 is a drowning sequence. The sequence O 3 l-1 overlapped the eroded slope and pinched out to the northwest and landward. The highstand systems tract in the sequence O 3 l-2 consists of low-angle sigmoid and high-angle shingled progradation configuration. Major sedimentary facies of the Lianglitage Formation include reef and shoal in the platform margin and lagoon, which can be subdivided into coral-sponge-stromatoporoid reef complex, sand shoal, lime mud mound, and intershoal sea. Reefs, sand shoals and their complex are potential reservoir facies. The reefs and sand shoals in the sequence O 3 l-1 developed in the upper of its highstand systems tract. In the sequence O 3 l-2, the highstand systems tract with an internal prograding configuration is a response to the lateral shifting of the complex of reef and sand shoal. The transgressive systems tract, in particular the sand shoals, developed widely on the slope of the platform margin and interior. The reefs in the sequence O 3 l-3 migrated towards high positions and formed retrograding reefs in the western platform and low relief in the platform interior. Basinward lateral migration of the reefs and pure carbonate rock both characterize highstand systems tract and show that the rise of the relative sea-level was very slow. Shingled prograding stacking pattern of the 4th-order sequences and reefs grow horizontally, which represents the late stage of highstand systems tract and implies relative sealevel stillstand. Reefs migrating towards high land and impure carbonate rock both indicate transgressive systems tract and suggest that the relative sea-level rose fast. Erosional truncation and epidiagenetic karstification represent a falling relative sea-level. The relative sea-level fluctuation and antecedent palaeotopography control the development and distribution of reef complexes and unconformity karst zones. Currently, the composite zone of epidiagenetic karstic intervals and high-energy complexes of reefs and sand shoals with prograding configuration is an important oil and gas reservoir in the northern slope of the Tazhong carbonate platform.Yang Xiaofa Lin Changsong Yang Haijun Han Jianfa Liu Jingyan Zhang Yanmei Peng Li Jing Bing Tong Jianyu Wang Haiping Li Huanpu 2010Petroleum Science2010,7,3:8

5Relationship between the parent charge transfer gap and maximum transition temperature in cuprates显示文摘One of the biggest puzzles concerning the cuprate high temperature superconductors is what determines the maximum transition temperature(Tc,max), which varies from less than 30 to above 130 K in different compounds.Despite this dramatic variation, a robust trend is that within each family, the double-layer compound always has higher Tc,maxthan the single-layer counterpart. Here we use scanning tunneling microscopy to investigate the electronic structure of four cuprate parent compounds belonging to two different families. We find that within each family, the double layer compound has a much smaller charge transfer gap size(DCT), indicating a clear anticorrelation between DCTand Tc,max. These results suggest that the charge transfer gap plays a key role in the superconducting physics of cuprates, which shed important new light on the high Tc mechanism from doped Mott insulator perspective.Wei Ruan Cheng Hu Jianfa Zhao Peng Cai Yingying Peng Cun Ye Runze Yu Xintong Li Zhenqi Hao Changqing Jin Xingjiang Zhou Zheng-Yu Weng Yayu Wang 2016Science Bulletin2016,61,23:3
6Application of butane geochemistry of natural gas in hydrocarbon exploration显示文摘In order to distinguish the source and migration direction of natural gas by geochemical characteristics of butane,the components and carbon isotopes of natural gas from major hydrocarbonbearing basins in China were analyzed.The results showed that:(1) Oil-type gas has i-C 4 /n-C 4 <0.8,δ 13 C butane <-28‰,δ 13 C i-butane <-27‰,δ 13 C n-butane <-28.5‰,whereas coal-type gas has i-C 4 /n-C 4 >0.8,δ 13 C butane >-25.5‰,δ 13 C i-butane >-24‰,δ 13 C n-butane >-26‰.(2) When δ 13 C i-butane-δ 13 C n-butane is greater than 0,the maturity of oil-type gas is generally more than 2.4% and that of coal-type gas is greater than 1.4%,whereas when the difference is less than 0,the maturity of oil-type gas is generally less than 1.1% and that of coal-type gas is less than 0.8%.(3) When natural gas migrates through dense cap rocks,the value of i-C 4 /n-C 4 increases,whereas when it migrates laterally along a reservoir,the value of i-C 4 /n-C 4 decreases.(4) Sapropelic transition zone gas with composition and carbon isotopic signatures similar to those of oil-type gas in the low thermal evolution stage is found to have a relatively high butane content.(5) The values of i-C 4 /n-C 4 and δ 13 C n-butane δ 13 C i-butane of gas which has suffered biological degradation are significantly higher than those obtained from thermogenic and bio-thermocatalytic transition zone gas.Thus,natural gas of different genetic types can be recognized through component analysis and carbon isotopic signatures of butane,the natural gas maturity can be estimated from the difference in carbon isotopic content between isobutane and n-butane,and the migration direction of natural gas can be determined from i-C 4 /n-C 4 ratios and transport conditions,which can also be used to thermogenic and bio-thermocatalytic transition zone gas.Miao Zhongying Chen Jianfa Wang Jing Wang Guannan ZhangChen Li Wei 2012Petroleum Science2012,9,4:3

13New equation to decipher the relationship between carbon isotopic composition of methane and maturity of gas source rocks显示文摘The identification of the origin and source of natural gas is always a difficult and hot issue.Hereinto,the maturity identification is one of the most important scientific problems.Many empirical equations have been established to decipher the relationship between the maturity of gas source rocks and the carbon isotopic composition of natural gas.However,these equations proposed often fail to identify the maturity of the source rocks correctly,which in turn prevents the identification of genetic types and source rocks of the natural gas because the petroliferous sedimentary basins in China are complex and diverse,with multiple sets of source rocks and different thermal history.In this paper,the oil-associated gas from the Permian lacustrine source rocks and the coal-derived gas from the Jurassic source rocks in Junggar and Turpan-Hami basins have been investigated to decipher the relationship between the maturity(vitrinite reflectance)of gas source rocks and the carbon isotopic composition of methane.The equations established areδ^(13)C_(1)=25lgR_(o)-42.5 for oil-associated gas,andδ^(13)C_(1)=25lgR_(o)-37.5 for coal-derived gas.These new equations are suitable for the maturity identification of source rocks in most petroliferous basins,and favorable for the identification of the genetic type and source of natural gas,which is very important to improve the geological theory of natural gas.Jianping CHEN Xulong WANG Jianfa CHEN Yunyan NI Baoli XIANG Fengrong LIAO Wenjun HE Limiao YAO Erting LI 2021Science China Earth Sciences2021,64,3:1

15Leakage of mantle helium from the Liaodong Peninsula, China显示文摘The isotopic compositions of helium have been investigated in hot spring gases sampled from the Liaodong Peninsula, China. The 3He/ 4He ratios range from 0.14 Ra (0.14 times the atmospheric 3He/ 4He ratio of 1.40×10 -6) to 0.72 Ra. 3He/ 4He versus 4He/ 20Ne ratios and He contents suggest that a small amount of mantle-derived helium reaches the earth’s surface. Helium isotope ratios of the hot spring gases show a distribution pattern similar to the regional heat flow values, indicating that the positive thermal anomaly occurring in the area is closely associated with the presence of mantle-derived helium. The observations described above provide some significant evidence that the molten magma originating from partial melting of the upper mantle may have intruded into the continental crust along the activity fault. The coupling of the presence of mantle He and heat flow anomalies to seismic activity in studied region seem to imply that there is an internal relationship between mantle degassing and seismicJianguo Ren Xianbin Wang Jianfa Chen Chunyuan Li Hui Yang Ziyuan Ouyang 1998Chinese Science Bulletin1998,43,9:1

17P2 asymmetry of Au's M-band flux and its smoothing effect due to high-Z ablator dopants显示文摘X-ray drive asymmetry is one of the main seeds of low-mode implosion asymmetry that blocks further improvement of the nuclear per-formance of“high-foot”experiments on the National Ignition Facility[Miller et al.,Nucl.Fusion 44,S228(2004)].More particularly,the P2 asymmetry of Au's M-band flux can also severely influence the implosion performance of ignition capsules[Li et al.,Phys.Plasmas 23,072705(2016)].Here we study the smoothing effect of mid-and/or high-Z dopants in ablator on Au's M-band flux asymmetries,by modeling and comparing the implosion processes of a Ge-doped ignition capsule and a Si-doped one driven by X-ray sources with P2 M-band flux asymmetry.As the results,(1)mid-or high-Z dopants absorb hard X-rays(M-band flux)and re-emit isotropically,which helps to smooth the asymmetric M-band flux arriving at the ablation front,therefore reducing the P2 asymmetries of the imploding shell and hot spot;(2)the smoothing effect of Ge-dopant is more remarkable than Si-dopant because its opacity in Au's M-band is higher than the latter's;and(3)placing the doped layer at a larger radius in ablator is more efficient.Applying this effect may not be a main measure to reduce the low-mode implosion asymmetry,but might be of significance in some critical situations such as inertial confinement fusion(ICF)experiments very near the performance cliffs of asymmetric X-ray drives.Yongsheng Li Chuanlei Zhai Guoli Ren Jianfa Gu Wenyi Huo Xujun Meng Wenhua Ye Ke Lan Weiyan Zhang 2017Matter and Radiation at Extremes2017,2,2:1
