Roger T. Ames, who teaches at the University of Hawai＇i at Manoa, is beyond any doubt one of the most prominent and original voices in current discourse on Chinese philosophy. For decades he has been extremely active in advocating an understanding of ancient Chinese texts that is explicitly philosophical, that is, it speaks directly to the philosophically minded （and not primarily to the philologically oriented sinologist）. Despite this clearly confined group of addressees, he speaks decidedly not in the terminology most familiar to practitioners of dominant or mainstream Westem philosophy. Although he frequently draws contrasts and analogies with more familiar figures and more general features of Western philosophy, his favorite approach makes it a point--in fact, the central point--to give Chinese philosophy a voice of its own and thus to read its texts ＂on their own terms＂（to be understood in its double meaning as conditions and vocabulary）. But, as Ames is very much aware, translating these texts on these terms still requires a vocabulary that is not their ＂own＂-and he has thus chosen dominantly the vocabulary of early American pragmatism as the most useful in articulating what he perceives are the sensibilities of Chinese philosophy. With his many interpretative studies and philosophical translations （often co-authored with David L. Hall and Henry Rosemont Jr.）, he has pushed the frontiers of Chinese philosophy as much as of philosophy in China in various ways and into various directions--something that has found an impressive echo both in terms of followers （many relate a story that they initially became interested in Chinese philosophy by having read, say, Hall and -Ames＇s Thinking Through Confucius） and in terms of critics, who have taken issue with particular translations, the overall approach, or with both.

Analysis of the role of branching angle in the dynamic rupture process on a 3-D branching fault system

引用

Earth and Planetary Physics 2020年第5期4卷 523-531页

作者： JingXing Fang Feng Qian haiming zhang School of Earth and Space Sciences Peking UniversityBeijing 100871China

The fault branching phenomenon,which may heavily influence the patterns of rupture propagation in fault systems,is one of the geometric complexities of fault systems that is widely observed in *** this study,we investigate the effect of the branching angle on the rupture inclination and the interaction between branch planes in two-fork branching fault systems by numerical simulation and theoretical analysis based on Mohr’s circle.A friction law dependent on normal stress is used,and special attention is paid to studying how ruptures on the upper and lower branch planes affect the stress and rupture on each other *** results show that the two branch planes affect each other in different patterns and that the intensity of the effect changes with the branching *** rupture of the lower branch plane has a negative effect on the rupture of the upper branch plane in the case of a small branching angle but has almost no negative effect in the case of a large branching *** rupture of the upper branch plane,however,suppresses the rupture of the lower branch plane regardless of whether the branching angle is large or small.

In recent years, clinical studies have found that acetone concentration in exhaled breath can be taken as a characteristic marker of diabetes. Metal-oxide-semiconductor (MOS) materials are widely used in acetone gas sensors due to their low cost, high sensitivity, fast response/recovery time, and easy integration. This paper reviews recent progress in acetone sensors based on MOS materials for diabetes diagnosis. The methods of improving the performance of acetone sensor have been explored for comparison, especially in high humidity conditions. We summarize the current excellent methods of preparations of sensors based on MOSs and hope to provide some help for the progress of acetone sensors in the diagnosis of diabetes.

Synthetic seismograms for finite sources in spherically symmetric Earth using normal-mode summation

引用

Earthquake Science 2017年第3期30卷 125-133页

作者： Tianshi Liu haiming zhang Department of Geophysics School of Earth and Space SciencesPeking University

Normal-mode summation is the most rapidly used method in calculating synthetic seismograms. How- ever, normal-mode summation is mostly applied to point sources. For earthquakes triggered by faults extending for as long as several 100 km, the seismic waves are usually simulated by point source summation. In this paper, we attempt to follow a different route, i.e., directly calculate the excitation of each mode, and use normal-mode sum- mation to obtain the seismogram. Furthermore, we assume the finite source to be a ＂line source＂ and numerically calculate the transverse component of synthetic seismo- grams for vertical strike-slip faults. Finally, we analyze the features in the Love waves excited by finite faults.

Review on modeling and simulation of microstructure evolution during dynamic recrystallization using cellular automaton method

引用

Science China(Technological Sciences) 2020年第3期63卷 357-396页

作者： ZHU HuaJia CHEN Fei zhang haiming CUI ZhenShan Department of Plasticity Technology Shanghai Jiao Tong University

The macro-mechanical properties of metal and alloy are largely depended on their chemical composition and microstructures resulting from the complicated processing and heat treatment history in industrial production. During these thermoplastic processes, dynamic recovery, dynamic recrystallization, static recovery and static recrystallization are the key microstructural evolution mechanisms. Accurate prediction and precise control of the microstructural evolution are of great importance for designers to achieve excellent mechanical properties for metals and alloys through hot working. Up to date, dynamic recrystallization has been recognized as a powerful mechanism for grain refinement. In-depth understanding of the microstructural evolution of dynamic recrystallization and furthermore to accurately predict and control the microstructure evolution during dynamic recrystallization process has become a research focus in the field of plastic processing. Cellular automaton(CA) method has been commonly employed to simulate the microstructure evolution of dynamic recrystallization due to its unique advantages,for example, it is easier to represent topological features and more realistically reflect the grain boundary migration process. In this paper, the basic ideas and characteristics of the CA method are briefly introduced. The physical mechanisms of dynamic recrystallization are summarized. Meanwhile, the state-of-the-art overview of the CA method of simulating the DRX process is introduced. Furthermore, this paper points out several problems that need to be solved urgently and prospects the development trend of the CA method for simulating the microstructure evolution in dynamic recrystallization.

Earthquake Science 2017年第3期30卷 115-123页

作者： Xi Feng haiming zhang Department of Geophysics School of Earth and Space SciencesPeking University

We present an equivalent form of the expres- sions first obtained by Tada （Geophys J Int 164：653-669, 2006. doi： 10.1111/j. 1365-246X.2006.03868.x）, which rep- resents the transient stress response of an infinite, homo- geneous and isotropic medium to a constant slip rate on a triangular fault that continues perpetually after the slip onset. Our results are simpler than Tada＇s, and the corre- sponding codes have a higher running speed.

Theoretical prediction on the stability, electronic structure, room and elevated temperature properties of a new MAB phase Mo2AlB2

引用

Journal of Materials Science & Technology 2019年第12期35卷 2926-2934页

作者： Yanchun Zhou Huimin Xiang haiming zhang Fu-Zhi Dai Science and Technofogy on Advanced Functional Composite Laboratory Aerospace Research institute of Maferids Processing Technofogy.No.1 South Dahongmen RoadBeijing 100076China School of Mechanical Electronic and Control EngineeringBeijing Jiaotong UniversityBeijing 100044China

Mo2AlB2 is a new MAB phase that has been observed in thin foils of Mo Al B during TEM observation and in Na OH etched Mo Al B samples. However, the structural characteristics, chemical bonding and properties of this new compound have not been investigated. In this work, geometry optimized crystal structure of Mo2AlB2 is obtained and its stability, elastic and thermal dynamic properties are investigated. Mo2AlB2 is stable in Al lean conditions, which is consistent with the exiting experimental results. It is also gauged as a damage tolerant or quasi-ductile ceramic based on the low Pugh’s shear to bulk modulus ratio(G/B = 0.544) and positive Cauchy pressure in all three crystallographic directions, which is underpinned by the metallic bonding. Mo2AlB2 also exhibits high stiffness which is attributed to the strong B–B covalent bond chains within its crystal structure. Due to the anisotropic chemical bonding, Mo2AlB2 has anisotropic thermal expansion coefficients αa= 6.19 × 10^–6 K1, αb= 12.13 × 10^-6 K^–1, αc= 6.66 × 10^-6 K^–1,respectively, along a, b and c directions in the temperature range between 300 and 1500 K. The heat capacity from 300 to 1500 K can be described as Cp= 120.32 + 0.01648 T-2.597 × 10^6 T^-2(J·mol^–1·K^–1).The elastic constants decrease almost linearly with temperature. The elastic constants representing the resistance to principle deformation(c11, c22 and c33) decrease in faster rates than those representing shear deformation resistance(c44, c55 and c66). Correspondingly, bulk and Young’s modulus decrease in faster rates than shear modulus. In light of the structure-property relations of Mo2AlB2, it is suggested that future damage tolerant ceramics can be designed by putting stiff covalent bonding units into soft metallic bonding box to obtain both high stiffness and quasi-ductility.

Increased Uterine NK-Derived IFN-γand TNF-αin C57BL/6J Mice during Early Gestation

引用

Cellular & Molecular Immunology 2006年第2期3卷 131-137页

作者： Xiaoyan WU haiming Wei Jianhong zhang Zhigang Tian Hefei National Laboratory for Physical Sciences at Microscale School of Life Sciences University of Science and Technology of China Hefei 230027 Anhui China

Natural killer （NK） cells are bone marrow-derived lymphocytes. They produce cytokines that regulate the development of acquired immunity. In view of their accumulation at the maternal-fetal interface, uterine natural killer （uNK） cells are also thought to play essential roles during pregnancy. Our results compared the differences of cytokine secretion profile by NK cells in uterine endometrium, liver, spleen and peripheral blood, and focused on the cytokines secretion by uNK cells. It was demonstrated that the expression of IFN-γ and TNF-α in uterine endometrium of pregnant mice are lower than those in liver, but they increase significantly during pregnancy. Our study showed that the number of uNK cells was increased significantly during pregnancy. They produced more IFN-γ and TNF-α than other organ-derived NK cells, and they also secreted minor amount of IL-4 and IL-5. The results indicated that the IFN-γ and TNF-α produced by uNK cells ensured a successful pregnancy progress.

Dynamic rupture process of the 1999 Chi-Chi,Taiwan,earthquake

引用

Earthquake Science 2009年第1期22卷 3-12页

作者： haiming zhang Xiaofei Chen College of Earth Sciences Graduate University of Chinese Academy of Sciences Beijing 100049 China School of Earth and Space Sciences University of Science and Technology of China Hefei 230026 China

In this study, we preliminarily investigated the dynamic rupture process of the 1999 Chi-Chi, Taiwan, earthquake by using an extended boundary integral equation method, in which the effect of ground surface can be exactly included. Parameters for numerical modeling were carefully assigned based on previous studies. Numerical results indicated that, although many simplifications are assumed, such as the fault plane is planar and all heterogeneities are neglected, distribution of slip is still consistent roughly with the results of kinematic inversion, implying that for earthquakes in which ruptures run up directly to the ground surface, the dynamic processes are controlled by geometry of the fault to a great extent. By taking the common feature inferred by various kinematic inversion studies as a restriction, we found that the critical slip-weakening distance Dc should locate in a narrow region [60 cm, 70 cm], and supershear rupture might occur during this earthquake, if the initial shear stress before the mainshock is close to the local shear strength.
