The results indicate that as the value of fractal dimension is increased, the interfacial static friction coefficient first increases and then decreases; the interfacial static friction coefficient decreases as the fractal roughness parameter increases; while the inter-facial static friction coefficient increases as the material property or total normal load increases; the curve of static friction coefficient versus dimensionless total normal load is convex when the fractal dimension becomes smaller or fractal roughness parameter is larger or material property becomes smaller.

研究结果表明：界面的静摩擦因数首先随分形维数的增加而增加，然后随分形维数的增加而减小；界面的静摩擦因数随分形粗糙度参数的增加而减小，但随材料特性的增加而增加，也随总法向载荷的增加而增加；当分形维数较小或分形粗糙度参数较大或材料特性较小时，静摩擦因数－量纲一的总法向载荷曲线为凸弧。

Though it is a long history of the research on static friction, many problems, such as relationship between static friction and static contact time, the relationship between static friction and load, and the prediction of static friction coefficient have not yet fully studied.

虽然静摩擦的研究历史很悠久，但仍有一些问题没有解决，如静摩擦与静止接触时间的关系，静摩擦与载荷的关系，以及静摩擦系数的预测等问题。

Therefore, the torque required to open the gate valve required torque than the closure of large, in addition, for a pair of contact between the sealing surface, the Non Rising Stem Resilient Seated Gate Valves coefficient of static friction between them than the dynamic friction coefficient, to make them from the static state generate the relative movement is required to exert greater force to overcome the static friction; due to temperature changes, so that the sealing surface pressure between the larger, need to overcome the static friction force also will be bigger, so that when you open the valve on the stem nut on the sometimes increase the torque exerted a lot.

所以，开启闸阀所需的力矩比关闭闸阀所需的力矩大，此外，对于一对互相接触的密封面来说，它们之间的静摩擦系数也比动摩擦系数大，要使它们从静止状态产生相对运动，需施加较大的力以克服静摩擦力；由于温度变化，使密封面间的压力变大，需要克服的静摩擦力也随之变大，从而使开启闸阀时，对阀杆螺母上施加的力矩有时会增大很多。" Moment analysis of valve operation "是由中国闸阀网提供的国际阀门新闻，译文仅供参考。另外，中国闸阀网还提供相关产品搜索：闸阀型号、闸阀价格、闸阀技术、闸阀新闻、闸阀生产商等。

The friction performances of carbon face were investigated with an inertia friction tester. The torque curve of carbon face was ideal, the coefficient of static friction was lower than that of dynamic in 0.28 MPa, the friction coefficient of static and dynamic decreased with the braking pressure increasing. To the fiber face, the coefficient of dynamic friction of carbon face was more stable in cycle braking process, the wear rate was lower, and it was efficient to protect the couple plate not to be worn.

结果表明：碳质层的摩擦力矩在制动初期上升较快，中间过渡区平稳，尾部翘起较小；在制动压力小于0.28 MPa时静摩擦系数小于动摩擦系数，且动、静摩擦系数均随制动压力增加而减小；相对纤维层而言，采用碳质层摩擦时摩擦力矩曲线形态更好，连续制动时摩擦系数波动较小，磨损率低且能够有效保护偶件，是1种静/动摩擦系数比较低且适用于高载荷工况条件下使用的摩擦材料。

The law of factors' affecting degree, which influences the parameters between geogrids and soils in the pulling-out procedure, is obtained. With the concept of 'equivalent pull-out displacement' brought forward, the whole process of pull out tests is divided into two process-" main process (when x 1.0)" and "residual process (when x 1.0)", and three stages-static friction resistance stage, slip friction resistance stage, and residual friction resistance stage.2 The value of friction coefficient between reinforcement and soil varies with their definitions of friction, but each factor' s affecting degree influencing friction pa
