This thesis discusses the following. First, we use the condition of inference and the concept of wildhabor cone to design the addendum circle. Second, we use TCA technique to obtain the relationship between the slip track and the angle of action, which then leads to the calculation of contact ratios. We can then design the tooth face width and the numbers of teeth based on contact ratios.

本文一开始先对空间渐开线齿轮之齿冠圆范围使用齿轮干涉条件与Phillips提出的Wildhabor Cone进行设定，再利用Litvin提出的齿面接触分析方法，得到空间渐开线齿轮对在啮合过程中作用角与滑动轨迹之间的关系，藉由此关系可以建立一套设计流程来调整齿面宽以及齿数等参数，使其能符合设计需求。

Now, spurred by increasing numbers of international adoptions, greater acceptance of adoption by single parents and gays/lesbians, and the efforts of the late Dave Thomas, founder of Wendy's and himself an adoptee, more companies are offering benefits to adoptive parents.

In this paper, major agronomic traits and grain quality traits affecting rice yield and grain quality were investigated in seven aromatic rice maintainer lines bred in Sichuan and one variety introduced from America. It was aimed at estimating the numbers of gene controlling aroma, the allelism of aroma genes, location of aroma gene on the chromosome, and molecular tagging of aroma gene.

本研究利用四川新育成的七个香稻保持系(D香1B、D香2B、内香2B、内香4B、绵香2B、绵香3B、宜香1B)、一个香稻引进改良品种(泸香90)和一个非香型保持系为材料，研究了香稻保持系主要农艺性状和品质性状对品质、产量的影响，并且通过杂交群体构建对香稻香味性状进行了遗传分析。

It will lead to the apriorism if we introduce the mode of the US Securities Class Action as the civil compensation mechanism of solving the securities dishonesty only because the mode of the US Securities Class Action has a series of advantages compared with the representative action with uncertain numbers of people in our country.

如果仅仅因为美国证券集团诉讼模式比我国的人数不确定的代表人诉讼具有一系列的优势，即要引入此模式作为解决证券欺诈民事赔偿机制，容易出现先验主义的错误，我们必须注意到两国在法律传统、法律体制和法律文化基础等方面的差别。
