- mechanical contact arc 机械接触弧
- The results show that the plastic flow of the metal material nearby contact arc area towards free surface of workpiece becomes the burr under the coupling actions of the thermal and mechanics. 结果表明，在磨削淬硬加工中的热和机械复合作用下，磨削弧区附近金属向工件两侧无约束自由表面塑性流动形成了两侧方向毛刺；
- The effects of cutting area,contact arc length,the geometry of cutting face,back dip angle of PDC cutter and rock performance on force of PDC cutter breaking rock were simulated experimentally. 试验模拟了切削面积、接触弧长、切削面形状、切削齿后倾角和岩石性能对PDC切削齿破岩受力的影响。
- Based in simulation, the results of the roll force in the contact arc, the friction force in the contact arc, and the relation of the contact friction and the roll force are gained. 得出了轧制力沿接触弧的分布、摩擦力沿接触弧的分布及接触摩擦与轧制力的关系等一些有意义的结果。
- This paper presents the original well bottom model and PDC bits model, and two concepts are defined: contacting arc length and threshold WOB. 为方便分析,假设了原井底模型和PDC钻头模型,定义了接触弧长和门限钻压两个概念。
- In the hardware world, controls like pushbuttons that have mechanical contacts can exhibit what engineers call bounce, which means that the tiny metal contacts of the switch literally bounce when someone presses them. 在硬件方面，像按钮那样的控件有机械接触时就会表现出工程师称之为“颤动”的特性。 即当有人按压开关的小金属触点，它们就会颤动。
