各向同性的材料 meaning in Chinese

isotropic material

But the precondition of this method is that the material must be the elastic isotropy . for the elastic anisotropy , because of the difference in the each direction of mechanical properties , actually , the result of the nanoidentation load - displacement data is the synthesis of the mechanical properties in every direction
但是这种方法的一个前提是各向同性的材料，对于各向异性的材料，因为机械性质在各个方向上不同，所以在一个方向上的压痕试验结果实际上是各个方向不同材料性质的一个综合值。
