1SHRIMP U-Pb dating for a K-bentonite bed in the Tieling Formation,North China显示文摘A SHRIMP U-Pb zircon age of 1437±21 Ma was obtained for a recently discovered K-bentonite bed in the Tieling Formation,situated northeast of Beijing at the boundary between Liaoning and Hebei provinces,on the northern margin of the North China Craton(NCC).The SHRIMP U-Pb age places Tieling Formation near the end of the Calymmian Period of the early Mesoproterozoic Era.In addition,a SHRIMP U-Pb zircon date of 1372±18 Ma was acquired for K-bentonite beds in the overlying,dark-shale-dominated Xiamaling Formation from the same location northeast of Beijing.This date assigns a similar Mid-Mesoproterozoic(Ectasian Period) age for the Xiamaling Formation,as have previously determined dates from other sections northwest of Beijing.These dates indicate that the Tieling and Xiamaling formations,as well as the related succession in the eastern part of the Yanshan Mountains,represented by the well-known Meso-to Neoproterozoic standard section in Jixian,can be correlated well with sections northwest of Beijing in the western part of the Yanshan Mountains.In other words,the boundary between the Calymmian and Ectasian periods in the northern parts of the NCC is marked by the unconformity between the Tieling and Xiamaling formations in the northern NCC.This boundary was previously ascribed to the 'Qinyu Orogeny' and thought to be of Grenville age.In this regard,the conventional 'Qinyu Orogeny' should now be regarded as a short-lived regional uplift during Early Mesoproterozoic time,rather than a result from the Grenvillian assembly of the NCC to the Rodinia Supercontinent(~1.0 Ga).SU WenBo LI HuaiKun HUFF W D ETTENSOHN F R ZHANG ShiHong ZHOU HongYing WAN YuSheng 2010Chinese Science Bulletin2010,55,29:30
2ALDH2 protects against stroke by clearing 4-HNE显示文摘(ALDH2 ) 醛脱氢酶 2 是使象 4-hydroxy-2-nonenal (4-HNE ) 那样的乙醇和有毒的醛产生代射变化的 mitochondrial 酶。用不偏的 proteomic 搜索,我们作为与自发地高血压的老鼠(SHR ) 相比在击容易的自发地高血压的老鼠(SHR-SP ) 识别了 ALDH2 缺乏。我们作为 overexpression 在 neuronal 损害结束了 ALDH2 缺乏的原因的角色或 ALDH2 的激活由清除 4-HNE 在授与 neuroprotection 在 vitro 研究。进一步, ALDH2 击倒的老鼠揭示了 PKCε 的 neuroprotective 效果的缺席;。被知道对击施加保护的中等乙醇管理被显示提高 4-HNE 的 detoxification,并且免于 ischemic 通过 PKCε 的服的损害; -ALDH2 小径。在 SHR-SP,浆液 4-HNE 水平固执地与 lifespan 相反地被提高并且相关。在在人的击的 4-HNE 的角色被它的血浆层次的坚持的举起也在击以后建议至少 6 个月。最后,我们观察到发展了的跟随 8 年的 1 242 个题目中的 21 个比没得中风的那些摸有的更高起始的血浆 4-HNE 层次。这些调查结果建议 ALDH2 小径的激活可以在击容易的题目的鉴定用作一个有用索引,并且 ALDH2 小径可以是在击的治疗学的干预的一个潜在的目标。Jin-Min Guo Ai-Jun Liu Pu Zang Wen-Zhe Dong Li Ying Wei W ang Pu Xu Xu-Rui Song Jun Cai She-Qing Zhang Jun-Li Duan Jawahar L Mehta Ding-Feng Su 2013Cell Research2013,23,7:19
3NEW SOLUTION SYSTEM FOR CIRCULAR SECTOR PLATE BENDING AND ITS APPLICATION显示文摘Instead of the biharmonic type equation,a set of new governing equations and solvingmethod for circular sector plate bending is presented based on the analogy between plate bending andplane elasticity problems.So the Hamiltonian system can also be applied to plate bending problems byintroducing bending moment functions.The new method presents the analytical solution for the circu-lar,sector plate.The results show that the new method is effective.Yao, W Zhong, WX Su, B 1999Acta Mechanica Solida Sinica1999,12,4:15
4Investigation on reversible pump turbine flow structures and associated pressure field characteristics under different guide vane openings显示文摘The use of reversible pump turbines(RPT) within pumped storage power plants goes with prolonged periods of off-design operating conditions, which leads to the onset of operating mode-dependent instabilities. In order to decrease the gravity of RPT flow instabilities and associated damages or even completely eliminate them, a deep understanding of its onset and development mechanism is needed. In line with this, the present study seeks to numerically investigate the onset and development mechanism of RPT unsteady flow structures as well as the evolutional characteristics of associated pressure pulsations throughout the RPT complete flow passage, under off-design conditions for three GVOs namely 17, 21, and 25 mm. The study results showed that low torque operating conditions and associated vaneless space back flow structures were the trigger of flow unsteadiness onset within the RPT vaneless space, the instabilities which grew to cause the S-shape characteristics appearance. Moreover, the runner flow unsteadiness was found to decrease with the GVO increase. On the other hand, the GVO increase worsened the pressure pulsation levels within RPT flow zones, where pressure pulsations within the vaneless space and flow zones in its vicinities were found to be the most sensitive to GVO changes.BINAMA Maxime SU WenTao CAI WeiHua LI FengChen WEI XianZhu MUHIRWA Alex GONG RuZhi WEKESA David W 2019Science China(Technological Sciences)2019,62,11:5
5Raman determination on micro-diamond in eclogite from the Dabie Mountains, Eastern China显示文摘THE micro-diamond inclusions in garnet from eclogite in the Dabie Mountains have been reported by the present authors. However, Prof. Liou, J. G. and Dr. Zhang, R. Y. from the Stanford University of USA have expressed their doubts about our discovery of micro-diamond, considering its weak intensity of Raman peak in our determination. Recently, we have determined the micro-diamond inclusion from the same sample 9010574 (fig. 1), testedXu, ST Su, W 1997Chinese Science Bulletin1997,42,1:3
6First-Principles Study of Phase Stability and Mechanical Property of Co_3(Al,W) Precipitates with Different Ratio of Al to W in Co Base Alloys显示文摘The energetics, electronic structure and mechanical property of Co3(Al,W) precipitates with different ratio of Al to W in Co base alloys were investigated by the method of supercell and augmented plane waves plus local orbitals within generalized gradient approximation. The calculated results show that the L12 Co3(Al,W) precipitate is the most stable when the ratio of Al to W is equal to 1. When the content of W is higher than 18.5 at%, the L12 and hexagonal structures co-exist in Co3(Al,W) precipitates at 1173 K. It is also shown that the L12 ordered Co3(Al,W) precipitates have an obvious strengthening effect in the disordered fcc cobalt matrix.Yao Q Su X M Yan Y Zhao L W Sun J 2009稀有金属材料与工程2009,38,A03:3
