Through transformation of parameters, the meshing design system among Hy-Vo silent chain, sprocket and hob was built up based on the research of the pitch increment and the equivalent apothem increment of the effects on the common normal line length when the Hy-Vo silent chain was wrapped around and located on the sprocket, with the proper meshing conditions of Hy-Vo silent chain and sprocket into consideration. The design method of common normal line length was put forward that can be used when the value of the sprocket pressure angle was equal or unequal to the value of the Hy-Vo chain plate pressure angle.

Hence, we first analyzed and studied the kinematics and dynamics of PDC bit, and that are utilized to analyzed how to hame cutters by PDC bit whirlpool. Onthe based of this, we do the cutting experiments. With the test, we not only think over the influence to force actting on cutters in rock nature, drilling parameter, cuttersdensity distributed, and also wear state of cutters and PDC bit appearance. Because the PDC bit's cutters are repeaded by polycrystalline-diamand and tungsten carbide, the specific property of PDC wear are not alike that of polycrystalline-diamand and not alike tungsten carbide.

因此，本文首先分析研究了PDC钻头的运动学和动力学，并利用分析的结果对PDC钻头的涡动是如何损坏切削齿的进行了探讨；在此基础上，进行了PDC钻头切削齿的受力实验，在受力实验研究中，不仅考虑了岩性、钻进参数、布齿密度等对切削齿受力的影响，而且考虑了切削齿不同的磨损状态、钻头的冠部形状对切削齿受力的影响；PDC钻头的切削齿是由聚晶金刚石层和碳化钨底层复合而成的，它的磨损特点既不同于金刚石的磨损又不同于碳化钨的磨损，因此，在分析了复合片磨损机理的基础上，进行了PDC钻头切削齿的磨损实验。

Both upper and lower dental study models were collected from 30 boys (12 years old) and 30 girls (12 years old) with acceptable normal occlusion to understand the characteristics of the crown size, dental arch width and length such as (1) mesiodistal diameters of crown size from central incisor to first molar,(2) the width and length of dental arch and basal arch and (3) the morphology of dental arch form. After statistical analysis, data were compared with Japanese, Central and South American Indians and North American Caucasians from papers. The results were:(1) There was no statistical difference in teeth size between males and females, except the upper first molar of males was larger than that of females, lower central incisor of males was smaller than that of females.(2) The dimensions of dental arch of males were larger than that of females in general, especially such items as width and length of basal arch.(3) The crown size of Chinese male was in generally smaller than that of four other races, especially the upper canine, lower central incisor and first molar.

为了解住在台湾的中国人其牙齿的大小，齿列弓幅径及形态，为齿科人类学上的特微，以期能对儿童牙科，齿颚矫正科之临床及齿科基础医学能有所贡献，抽取12岁学童男女各30名共60名，可接受为正常咬合之上下颚齿列模型，测量其上下颚(1)左侧正中门牙到第一大臼齿共计12颗恒牙之牙冠近远心径，(2)齿列弓宽径、长径及齿槽基底宽径、长径，(3)齿列弓之形态，以上资料经统计分析作t-test检定，并与诸学者对日本人、北美白人、中美及南美印第安人人种的研究结果作检讨得知；(1)男女性恒牙的近远心径无明显差异，但男性上颚第大臼齿比女性者大，下颚正中门牙比女性者小；(2)男性的齿列弓幅径比女性者为大，尤以齿槽基底宽径及长径最显著；(3)国人男子的牙齿近远心径比其他四人种者为小，特别是国人的上颚犬齿，下颚正中门牙及第一大臼齿最小。

From the simulations, we can see the distributions and transmission of strain and stress in model under different loadings, and the results explained the fractures very well. 4. Similarly, a axis FEM model was constructed to simulate the axis fracture, emphasized on the odontoid process. Three kind of odontoid process fracture were analysed on this model, which occurred respectively on the tip, the middle and the fundus. The results gave the best angle to fracture the odontoid process of the axis.
