各向同性弹性介质 meaning in Chinese

isotropic elastic medium

The paper consider bone tissue as an biphasic porous medium , which is composed of solid bone matrix and liquids as extracellular fluid . on the other hand , bone tissue can produce electric potential when it is subjected to outside force . so dynamic governing equations can be established through combining the biphasic porous medium model and the streaming potential model , which describe the coupling between the distortion and fluid flow as well as the streaming potential
论文首先考察了骨组织的生理形态结构及其组成，据此将骨组织模型化为一种由固体骨基质和由细胞外液和血液等组成的液体所构成的两相饱和多孔介质，并进一步假设固体骨质为各向同性弹性介质，而孔间流体为理想流体；另一方面，骨组织在受到应力作用变形后能够产生电位。
