The Indirect Effect of the Internal Forces on the Linear Angular Momentum of A System of Particles

It is demonstrated that if the vector sum of the external forces and the total external torque are functions of all the positions and the velocities of the particles, the internal forces will affect indirectly the linear momentum and the angular momentum of a system of the particles through the and. In order to ensure that the internal forces have no effect on the and of the system, the external forces must be restricted to a linear function of and. Some examples which show that internal forces do affect the motion of the center of mass and the angular momentum of the system were discussed.     

A Tentative Interpretation of the Picture of Dorian Gray with Psychoanalytical Method

This paper applies Freudian psychoanalytical method to interpreting the characteristics of the three heroes in the Picture of Dorian Gray. Based on Freud＇s theory of psychoanalysis, the paper presents that the harmony of the tripartite personality is the underlying highlight of the novel and concludes that the concepts of the id, the ego, and the superego correspond with the images of Lord Henry, Dorian Gray and Basil Hallward respectively. And this paper claims that Dorian Gray＇s self - destruction is the most extreme development of the imbalance between the superego and the id.     

On Strategies in English Listening at Junior Middle Schools in Rural Areas

It is so disappointed that at present, the students’ listening ability is extremely poor, especially that of the middle school students in rural area. There are plenty of factors that cause this problem, among which there are three major reasons. They are the insufficient equipment in the school, the lacking of interest of the students and the difficulty in the listening study.     

Environmental effects induced by excavation

Based on 3D Biot＇s consolidation theory and nonlinear Duncan-Chang＇s model, a 3D FEM （finite element method） program is developed considering the coupling of groundwater seepage and soil skeleton deformation during excavation. The comparison between the analysis result considering the variation of water head difference and that without considering it shows that the porewater pressure distribution of the former is distinctly different from that of the latter and that the foundation pit deformations of the former are larger than those of the latter, so that the result without considering the variation of water head difference is unreliable. The distribution rules of soil horizontal and vertical displacements around the pit and excess porewater pressure are analyzed in detail in time and space, which is very significant for guiding underground engineering construction and ensuring environment safety around the pit.     

有序无序转变对金属间化合物环境氢脆敏感性的影响

The mechanism involving the effect of disorder/order transformation on the environmental embrittlement in gaseous H2 is summarized. It is shown that there is no hydrogen embrittlement in disordered state of Kurnakov type intermetallics in gaseous H2. However, the H2-induced environmental embrittlement for the ordered alloy having identical chemical composition becomes severer as the degree of the order increases. The results of testing on the ion gage turned on and off during tensile testing show that the more sensitive to H2-induced hydrogen embrittlement for ordered alloy than disordered one is attributed to the fact that atomic ordering may accelerate the kinetics of the catalytic reaction to produce more atomic hydrogen. The results on simultaneous hydrogen charging show that disordered alloys embrittled as hydrogen atoms are forced into the material implying that the embrittlement of ordered alloy in gaseous H2 is also due to the acceleration of the kinetics of catalytic reaction. The above suggestion was further verified by the adsorption tests of Ni3Fe intermetallics powder. It is shown that the amount of chemically adsorbed hydrogen in ordered state is significantly larger than that adsorbed by the disordered alloy, indicating that the more sensitive to H2-induced embrittlement in the ordered state of alloy is essentially due to the accelerated catalytic reaction.     

Analysis and simulation of molecular dynamics of lysozyme in water cluster system

The influence of water on protein conformation was investigated by simulating the molecular dynamics of a model protein lysozyme in different water systems.The lysozyme-water system with TIP3P water model and lysozyme-water cluster system with six-ring water model were evaluated.In addition,the radial distribution function of solvent around lysozyme was calculated.It is found that the distribution of water molecules around lysozyme is similar to that of water clusters.The analyses of dihedral angles and disulfide bonds of lysozyme show that the conformation of lysozyme is severely damaged in the lysozyme-water cluster system compared with that in the lysozyme-water system.This difference can be attributed to the formation of larger number of intermolecular hydrogen bonds between lysozyme and water cluster.It is in agreement with the analysis that water clusters can change the degree of denaturation in the process of heat denaturation of lysozyme.     

硼对金属间化合物Ni_3Fe氢气诱发环境氢脆的影响(英文)

In this paper the tensile properties of both ordered and disordered Ni-24Fe and Ni-24Fe-0.03%B(wt%)alloys in gaseous hydrogen was investigated.The result shows that the ductility of the disordered Ni_3Fe is significantly larger than that of ordered material in gaseous hydrogen.However,the ductility of ordered Ni3Fe doped with 0.03%B is nearly the same as that of disordered one indicating the obvious suppressing effect of boron on the H_2-induced embrittlement.Based on the segregation behavior of boron in Ni_3Al,it is proposed that the suppressing effect of boron in Ni_3Fe on the H_2-induced embrittlement is attributed to the segregation of boron on grain boundaries,thereby reducing the hydrogen diffusivity along the grain boundaries.
