＜正＞ The theoretical model of residual stress of ceramics grinding has been established applying thermal elastoplastic mechanics theory. While grinding at the course of grinding wheel moved along workpiece surface the distributing regulation of residual stress can be simplified into thermal elastioplastic mechanical issue, under the action of the both moving centralized force and heat source. Calculating and evaluating of surface residual stress using current procedure of finite element analysis which has been reformed is successful. Comparing with X-ray diffraction experiment method, satisfactory precision has been acquired. The results of experiment show the changing regularity of residual stresses after grinding A12.3 using diamond wheel, on condition that alter grinding parameters. The values of residual compress stress are taken place changing at key certain critical point on their figure as follow: When grinding depth ap is lower than 50 μm, the residual compress stresses are increased with grinding depth increasing, on the contrary as ap＞50 μm. At Vw＜8 m/min, the residual compress stresses increased rapidly with feed speed of work-piece increasing, on the contrary at Vw＞8 m/min. When Vs＜2. m/s the residual stress increased with wheel speed increasing and keep stable in value at Vs＞2. m/s. According to grinding mechanism the cause of residual stress transform has been explained.

盾构管片接头刚度系数一直是影响盾构管片设计计算结果正确性的直接影响因素。通过建立盾构管片及弯曲螺栓的三维非连续介质模型,以及设置合理的管片接头接触模型,消除了接头刚度系数对计算结果的影响。对盾构管片在实际荷载作用下的受力与变形情况进行研究。研究表明:管片拱顶与拱底接头向内侧张开,两侧拱腰接头向外侧张开。非连续介质模型中,盾构管片的分块拼装形式以及管片间连接螺栓单元的设置改变了管片环的整体刚度,管片接头附近出现了不均匀的波浪形云图。相对于惯用法模型,三维非连续介质模型的轴力值在接头处有明显突变,并且其最大正弯矩值小于惯用法模型计算结果。两种计算方法得出的最大负弯矩值相差不大,本次研究取得的成果对盾构管片设计工作有一定的参考价值。

＜正＞ Integrated standardization is one of the fundamental forms of modern standardization. It is the combination of system science and the content of standardization. The development of system science has provided theoretic foundation and precondition for integrated standardization. The relevant research on integrated standardization and system engineering illustrate that integrated standardization is a advanced method which presented with the development of modern science and technology . Integrated standardization treat the relevant factors of standardization as a system, and wholly standarlize the factors in order to reach the best level of technology and *** standardization is a large system engineering. In modern industry the contact among different departments is being constantly enlarged and the complexity of product is being constantly increased. This situation demands strict correspond and united request in all the following aspects;raw material, organs, fittings, technical measures of production, preparation for production, ways of organizing the production. The traditional measure which establish the respective standard separately must be replaced by multi-spetialty standardization in large spectrum. The current situation and the development of system science has provided theoretic foundation and precondition for this kind of standardization. Product or project can be managed with system engineering of project, while the correspond standardization can be managed with system engineering of *** standardization virtually is system engineering of standardization, which use the theory to deal with the problem about standardization . This thesis included 3 chapters;1. the brief summary of integrated standardization and system engineering management in the development of type in foreign countries;2. the current situation and existing problems in the development of products;3. how to organize and actualize integrated standardi

＜正＞ The effects of various content of Al on microstructure and magnetic properties of Nd2.e14B /α-Fe nanocomposite permanent magnets have been investigated in this article. Samples are prepared by melting spinning. The phase composite and magnetic properties have been analyzed and characterized. The changes of magnetic properties by annealing under different tem-perature have been researched. The results reveal that amorphous degree is more obvious and crystallization temperature of Nd2.e14B moves to high temperature with Al increase using a same processing. Compared with samples which contain no Al, ad-dition of Al obviously decreases the coercivity and the saturation magnetization of as-spun materials, but largely improves the properties of annealed samples.
