By using Morse potential model, we calculate the temperature dependence of critical resolved shear stress (CRSS) of some single crystals. Dislocation-phonon interaction is considered in this paper. Theoretical calculations fit experimental law well. Investigations show: interatomic force is the physical intrinsic that controls the plastic deformation processing of materials, and the temperature dependence of CRSS mainly comes from the temperature dependence of dislocation vibration.

INTRODUCTIONThere is abundant evidence that stressful insults suchas acute pancreatitis may significantly alter themetabolism of the gut mucosa and therefore itsbarrier integrity,resulting in an increase in mucosalpermeability and subsequent translocation of entericbacteria and their *** fact thatmost bacteria associated with acute pancreatic andperipancreatic infections are of enteric originimplies that the gut plays a major role in

Shear velocity is an important index for evaluating soil dynamic properties of the site. In this paper, the statistical relation of shear velocity with soil properties is set up by statistical analysis of shear velocities and relevant soil properties measured in Tianjin and Shanghai. The obtained formula has some referential value for the evaluation and classification of the site in offshore areas of China.

本文对生理载荷条件下(正常步态、爬楼梯和日常活动的混态载荷)骨水泥髋臼假体(牛髋骨试件)的失效机制进行研究。试验中利用髋关节仿真试验机施加生理载荷,利用人工仿真关节液来模拟体内生理环境,以测试髋臼假体的生命周期。在试验中通过微CT扫描仪观测并记载破坏的进程,并在试验结束后使用显微镜进行验证。结果表明,在所有载荷条件下,骨水泥-骨的界面松解是导致假体失效的原因,在体外环境条件下界面松解发生在髋臼窝中心的后上部区域,在体内生理环境下界而松解则发生在髋臼窝的所有区域。因此,模拟人体内部生理条件的试验环境是必需的,同时也确定髋臼假体的失效来自于力学和生物学因素的共同作用。
