This method displays the whole process of the contact between drill stem and casing-pipe wall. Gradual simulation is used to dynamically simulate the best position of appending non-rotating drill stem protector. By this way, we can find out contact points and contact force, then make certain the position and number of installing protector.

并采用逐步模拟法，对钻柱添加非旋转防磨减断保护套的最佳位置进行仿真分析，得到钻柱与套管壁的接触区域及接触力，确定非旋转防磨减断保护套的安装位置以及所需安装的数量，为合理使用非旋转防磨减断保护套提供理论依据和前提。

I n order to celebrate the Olympic Equestrian Event to be held in Hong Kong, our school has arranged an activity "Get in Touch with Equestrianism" for 50 students. In the Hong Kong Equestrian Centre, the participating students have learned the body and habits of horses.

为迎接二零零八年奥运马术比赛项目於香港举行，本校在五月十六日为五十名学生安排一项名为「马术全接触」的活动，让他们有机会近距离接触马儿。

General contact measurement error, the use of non-contact measurement is a better choice.

接触式测量一般误差较大，因此使用非接触式测量是更好的选择。

The company uses the advanced output controllable technology, with the face milling material set the suitable miller, change the traditional surface contact into line contact, make the output granularity evener, high product, widely used in chemical industry, metallurgy, glassed industry, and the high rquirement of the evenness for milling after milling, sand making of building sand in recent years.

公司采用先进的可控进出料技术，结合实际的研磨物料应配用合适的研磨体，以传统的面接触改为线接触，使出料粒度更为均匀，产量更高，广泛使用于耐材、化工、冶金、玻璃等行业对磨后成品均匀度要求比较高的研磨作业，近年来还用于建筑用砂的制砂行业等。
