The four single errors exist in joint B in crank.rocker mechanism. The result indicates that the theory analysis is correct. In order to analyze the distribution of contact stress in joints, the ANSYS finite element tool is used. The situation of four single errors in joint B is analyzed. The distribution of contact stress is actually reflected. The microcosmic stress analysis is referred.

And I followed a simple strategy: to outwork my opponents, do my job, and continue to preach new ideas, including college scholarships for all high school students with a B average or better; and a plant the future initiative to plant ten million more trees a year for a decade to do our part to reduce greenhouse gases and global warming.

我则采取了一套简单的策略：比我的对手的工作更努力，做好我的本职工作，继续宣扬新的理念，包括向成绩为B及B以上的高中学生提供大学奖学金，提交一个"为未来植树"的提案，用十年时间，每年再种植一千万棵树，为减少温室效应产生的气体和减缓全球气候变暖，尽我们的努力。

Furthermore, we believe that the general rules for understanding the superstructures formed within boundary areas are correlated directly with different overlapping or connecting operation with respect to building units of flattened hexagons and P-B polygons. These rules are as following:I The adjoined domains at least have their basic structural units a side-shared (that is, sharing two column clustersП) The basic structural units in both domains have overlapping area as large as possible.3 For theξ-Al-Ni-Rh phase formed in the as-cast Al75Ni15Rh10 alloy, phase transition processes induced by electron beam irradiation with different amount of dose were studied by in-situ observations in an electron microscope.

本论文提出了畴界的通用模型：各种畴界及其畴界处超结构都可以用一个通用的叠加覆盖模型去表示，覆盖的基本单元为扁六边形或P-B多边形，连接与覆盖规则如下：I相邻畴中的基本单元至少有一个共用边相邻畴中的基本单元重叠时沿b方向有最大重叠面积。3研究了Al75Ni15Rh10合金中ξ-Al-Ni-Rh相在透射电镜电镜中经不同剂量电子束辐照后引起的辐照损伤和相变过程。

Producing PHAs,and then were orientationally inserted into a prokaryotic expression vector pBV220. By analyzing the bioactibity and function of their products, the biological function of phaA, phaB and phaC was confirmed. These have been done in our laboratory. To make better use of the three genes by plant bioreactor, two groups of different plant expression vectors that can be used to produce PHAs in different plants were constructed, and the transformation of PHA in Oxalis triangnlaris has been preliminarily reseached.The following is the main results:Three plant expression vectors pBI121-A,pBI121-B and ubquiting-C, which can be used to be transformed into Oxalis triangularis were respectively constructed by using the phaA, phaB and phaC.
