常見(jiàn)例句雙語(yǔ)例句The frictional force remains constant, dependent on the friction, the kinetic friction coefficient, is always the same...摩擦力不守恒,它取決于摩擦力,動(dòng)能摩擦系數(shù),一直是相同的。It is pointed out that translational kinetic energy and rotational kinetic energy mutually transferred by sliding friction force, but it only has positive acting.討論滑動(dòng)摩擦力作功,說(shuō)明了滑動(dòng)摩擦力可以使剛體的平動(dòng)動(dòng)能和轉(zhuǎn)動(dòng)動(dòng)能之間相互轉(zhuǎn)換,但總是作負(fù)功。Popularization and application of ion nitrided titanium parts have shown that they are suitable for long-term use in harsh environment under kinetic load, friction force and corrosive media.耐磨性能和在還原性介質(zhì)中的耐蝕性能,可使鈦材在高度動(dòng)負(fù)荷、摩擦力和強(qiáng)腐蝕介質(zhì)三者同時(shí)存在的苛刻環(huán)境中長(zhǎng)期使用。 返回 kinetic friction force
