To understand the tissue forces of the esophagus, it is necessary to know the stress-strain relationships and the zero-stress state that is sensitive to structural and mechanical remodeling.

要明确食管的组织力则必须首先明确食管壁的应力—应变关系和零应力状态，而后者又直接反映了在应力作用下组织机械重建的结果。

And asymptotic state is a more common concept than critical state, which is a particular case when volumetric strain increment equals zero.

渐近状态是比临界状态更为广泛的一个概念，临界状态是渐近状态在体应变增量为零时的特殊情况。
