孔隙指数 meaning in Chinese

void index

The sedimentation compression lines , intrinsic compression lines can be normalized by a void index , then the difference of the structural clays and reconstituted clays are showed
天然粘土的沉积压缩曲线、重塑土的压缩曲线可以用孔隙指数来归一化，它清晰地显示出结构性土和重塑土的内在差别。
The sedimentation compression lines of natural clays , intrinsic compression lines of reconstituted clays and oedometer compression curves can be normalized by a void index , then the difference of the structural clays and reconstituted clays as well as the gradual damage course of soil structure are showed apparently
用孔隙指数来归一化天然粘土的沉积压缩曲线、重塑土的压缩曲线和固结仪压缩曲线，可以很清晰地揭示出结构性土与重塑土的内在差别、固结仪试验中土体结构性的渐进破坏过程。
