At first the research current situation of the flash temperature field of rough surface and the algorithm of contact problems with friction were reviewed in this paper 本文评述了粗糙表面的闪温以及摩擦接触算法的研究现状;建立粗糙表面接触模型并对其滑动摩擦界面的传热规律进行了研究。
Astronomers have long come to a similar conclusion : that the earth will be obliterated by a giant fireball as the sun burns up and expands so that its surface touches the planet 天文学家们也得出了相似的结论:由于太阳不断燃烧和膨胀,终有一天太阳表面会与地球表面接触,我们的地球会以此而被太阳这个巨大的火球所湮没。

Based on g - w contact model , two rough surfaces in contact were simplified to a smooth one and a rough one which has regular rectangular asperities , and a three - dimensional transient thermal and stress coupled fem model was established using thermal - structure sequential coupling . the course of the sliding with friction was simulated using the nonlinear multiphysics field fem , meanwhile considering thermal - elastic problems of the two bodies , to calculate and analyze the temperature , contact pressure and stress of the sliding contact surfaces with frictional heating 基于g - w接触模型,将两个粗糙表面简化为一个有规则排列的长方体微凸体的粗糙表面与一光滑表面,利用热结构顺序耦合建立三维瞬态有限元计算模型,考虑两个物体摩擦接触的热弹性问题,采用非线性有限元多物理场来实现,对粗糙表面接触模型的瞬时摩擦温度场、压力场和应力场进行了计算分析。
It was showed that sp method was easier than iesp method being used to prepare ms - smips , but sp method did n ' t suitable for high viscosity monomers to be used to prepare ms - smips . the compatibility of fe3o4 particles with monomers and polymers was solved through pre - encapsulation of fe3o4 particles by inverse emulsion in iesp method , the difficulty for sp method to disperse high viscosity monomers to turn into droplets was overcome as well , and precipitation did n ' t occur easily in aqueous recognition system , for the resulting ms - smips had a large quantity of air cores inside , hence had low density themselves . the 所制备的ms - pigms形态也为较好的球形,湿态时粒子表面具有大量分布较为均匀的孔穴,干态时因粒子收缩表面孔穴闭合;分散剂、引发剂、 fe3o4用量等均对ms - pigms形态有明显的影响;所制备的ms - pigms具有一定的磁响应性,并具有较好的分子识别性能,其对模板的识别主要靠印迹孔穴与模板蛋白质分子因非常近的表面接触而产生的众多氢键的协同作用。
