验证了体应变对数与压力对数的线性关系是由体应变与压力对数的线性关系导出的（Hashiguchi，1974）的各向同性固结方程与变形梯度的乘法分解完全相容（Lee，1969），这将是描述有限弹塑性变形的本构方程的基本要求之一。另一方面，强调了描述有限变形的本构方程虽然最常用的是孔隙比与压力对数的线性关系，但采用这种线性关系是不恰当的。
It is verified that the linear relation of logarithmic volumetric strain vs. logarithm of pressure derived from the linear relation of both logarithms of volume and pressure (Hashiguchi, 1974) for isotropic consolidation of soils is exactly compatible to the multiplicative decomposition of deformation gradient (Lee, 1969) which would be one of the fundamental requirements for constitutive equations describing the finite elastoplastic deformation. On the other hand, it is emphasized that the adoption of the linear relation of void ratio vs. logarithm of pressure is impertinent for the constitutive equation describing the finite deformation although it is most widely used for constitutive equations of soils.
