frictional coefficient

常见例句

Below 417℃, cobalt is in dense-hexagonal structure, it has lower frictional coefficient and sound wear resistance.
钴在417℃温度以下，为密排六方结构，具有低的摩擦系数，而具有很好的耐磨性。
The results showed that surface of different materials have obvious influence on the frictional coefficient while direction has no significant effect on it.
结果表明：摩擦方向对摩擦系数的影响不大，实际生产中主要需考虑摩擦基材面对摩擦系数的影响。
Modified factor of frictional coefficient of different sections of designed path of one field or area is obtained by statistical computing and analysis of more wells.
由多口井数据的统计计算和分析，可得某一油田或区块的水平井设计轨道各井段的摩阻因数放大因数。
