零件失效 meaning in English

part failure

All machinery motion is relative movement relying on its " spares pairs . abrasion happened with relative movement , and abrasion is the main cause of surface damage , spares invalid , and material friction loss
所有机器的运动都是依赖其零件副的相对运动，有相对运动就有磨损，磨损是导致表面损坏、零件失效和材料损耗的主要原因。
2 , states the complicated relativity in the mechanical system , then bases on the model of stress - strength interference , present that the relativity of between the stress and the strength of the parts is weak and the differences of the relativities of parts and the failure modes of part , and how to compute the related coefficient of parts and the related coefficient of the failure modes of part
2 、阐述了机械系统中复杂的相关性，以应力?强度相干理论模型为基础，指出机械零件的应力和强度之间不完全独立，以及零件失效模式之间的相关系数和机械系统中零件之间的相关系数求解，界定了零件之间的相关性和零件的失效模式相关性的区别。
