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。

The authors performed 3D photographic measurement on the technical moves of ZHANG Wen-xiu as an excellent female hammer thrower in China to get relatively comprehensive body movement data by using two JVC3000 high-speed cameras, screened and analyzed the data by using SPSS software, and revealed the following findings: in terms of such technical parameters as spinning time, spinning track and spinning speed, there were some problems with this player, which restricted the enhancement of her performance, such as the double leg supporting time was shorter than the single leg supporting time; the angle of inclination of the track of various swirls (espe-cially the first swirl) was somewhat too big; the accelerating process was too short; too much attention was paid to acceleration at the single leg supporting stage; the spinning at the double leg supporting stage was too fast; the sus-tainable accelerating power was not high.

摘 要：采用两台JVC3000高速摄像机对中国女子链球优秀运动员张文秀的技术动作进行三维摄影测量，获得较为全面的人体运动学数据；运用SPSS软件对数据进行筛选和相关分析，发现该运动员在旋转时间、轨迹和速度等技术参数方面存在着一些制约成绩提高的问题，诸如双支撑时间短于单支撑时间、各圈(尤其第1圈)的轨迹倾角偏大、加速过程太短、单支撑阶段过于强调加速及双支撑阶段旋转过快、持续加速能力不强等。
