The effect of load on the friction coefficient becomes small during the steadystage of wear.
磨损达到稳态后载荷对复合材料摩擦系数的影响不大。
2
There were drastic increase of true stress, drastic falling of true stress, steadystage and increase of true stress in its true stress-strain curve.
该材料的真应力-真应变曲线由应力激增阶段、应力下降阶段、稳态阶段和应力增加阶段组成;
3
The vibration acceleration signals at initial stage and steadystage in flowing granular media are tested, and the propagation of wave in the flowing field is analyzed.
