求翻译：岩石中自然存在着微空隙和微裂纹，因此，岩石是一种自然损伤的材料。受载岩石在超过弹性极限后表现出非弹性变形。造成岩石非弹性变形的主要或者直接因素有：是什么意思？

There is a natural rock micro-gaps and micro-cracks, thus, damage the rock is a natural material. Set by the elastic limit of rock over the performance of a non-elastic deformation. Non-elastic deformation caused by the major rock or direct factors are:

There is a natural rock in micro-gaps and micro-cracks, and therefore, the rock is a natural material injury. Rocks are contained in more than elastic limit performance after the non-elastic deformation. Non-elastic deformation of rocks caused major or direct factors are:

In the rock has the micro crevice and the micro crack naturally, therefore, the rock is one kind of nature damage material.Is carried the rock after to surpass the limit of elasticity to display the inelastic distortion.Creates the rock inelasticity to distort primary or the direct factor includes:

Naturally there is micro-gaps and micro-cracks in the rock, so damage of rock is a natural material. Loaded beyond the elastic limit performance of rock out non-elastic deformation. Inelastic deformation of rocks caused major or direct factors are:

Naturally there is micro-gaps and micro-cracks in the rock, so damage of rock is a natural material. Loaded beyond the elastic limit performance of rock out non-elastic deformation. Inelastic deformation of rocks caused major or direct factors are:
