接触

The results show that the contact resistance is greatly affected by the polymer content and the hydrophobic degree of carbon paper.

根据接触理论，运用非线性有限元方法对运载火箭的级间分离面进行了三种载荷工况作用下的接触分析。

The Catskill Mountains Many people see UFOs and report alien encounters in the Catskills. Silent Invasion 1991 - a book by Ellen Crystall - discusses over 100 UFO sightings and encounters in the Pine Bush area - over a 10 year period.

许多人们在Catskills中看见不明飞行物和报告不同的飞碟接触案例。1991的《无声的入侵》-亚伦克里斯托尔的一本书–在Pine Bush区域持续10年时间100以上的不明飞行物目击接触案例和相会中讨论。

Individuals on how to prevent sexually transmitted diseases: sexual contact, primarily through the spread of sexually transmitted diseases, such as the condyloma viral, bacterial of gonorrhea and non-gonococcal urethritis, chancroid, such as, first of all, should be avoided in patients with or suspected carriers with the occurrence of sexual contact.

个人如何预防性病：对于主要通过性接触而传播的性病，如病毒性的尖锐湿疣、细菌性的淋病以及非淋病性尿道炎、软下疳等，首先应避免与患者或可疑带菌者发生性接触。

Rotating speed of rotating machinery is a very important characteristic parameter.

旋转机械的转速是非常重要的特征参数，转速的计算主要有接触式和非接触式两种方式。

Avoid touching your face, and if you do, be sure your hands are clean.

避免接触脸，或者接触脸前，要确保你的手是干净的。

The corrosion rate of plain carbon steel contacted with higher coalification such as anthracite coal is 2 to 3 times larger than that in brown coal .

在相同的其它条件下，碳钢的腐蚀速率随接触的煤的煤化度提高而增加，与发育良好的无烟煤接触的碳钢的腐蚀速率是在煤化度相对较低的褐煤中的2～3倍以上。

The classical Hertz and JKR elastic contact theory is successfully applied to the plastic collision of cohesive particles. And the coefficient of restitution is then defined from the consideration of energy.

在经典Hertz弹性接触理论和JKR粘弹性接触理论的基础上，本文从理论上将其推广应用至粘附性颗粒塑性碰撞的情形，并从能量的角度定义了能够更加合理反映碰撞规律的弹性回复系数。

Statistic analysis result shows that the time step is the most important influence factor of simulation precision, and there is relation between simulation error and the setup value of restitution coefficient which the greater the setup value is, the less the simulation error is. Although there is no effect to the total contact time in the course of collision, the value of the time step decides the total contact step, and there is a logarithmic linear correlativity between them.

统计分析结果表明：计算时步是影响模拟精度最重要的因素；模拟误差还同恢复系数的设定值有关，设定值越大，模拟误差就越小；计算时步的大小虽然对碰撞过程的总接触时间影响不大，但是却决定了碰撞过程的总接触时步数，二者之间存在对数线性相关关系

Further study of this paper has shown that reason for"camel peak"phenomenon in the adhesion-creep test curves is difference between sliding-and static coefficient of friction and discussed the analytic formulae for line contact as well as one direction slip and special correction Lemk's method for point contact when their change is considered as stage jump function.

通过进一步的理论研究指出造成轮/轨粘着率与弹性滑移率实验曲线呈"驼峰"状的原因是滑动区和粘着区的动、静摩擦系数变化，给出了当它们为阶跃变化时线接触条件下的解析解和对点接触情况的独特的"修正"Lemke算法。
