采用上限方法，给出了多孔粘塑性材料正交流动法则存在的条件。

And, taking terms of an upper bounded approach, the existence condition for a normal flow regulation is obtained for the voided viscoplastic material.

蠕变过程中粘塑性变形占主导，因而其三轴蠕变曲线没有出现渐进流动阶段。

Because of the dominance of viscoplastic deformation in the creep process, creep curves under triaxial compression behave without the third phase of atypical creep curve, viz.

本文对两种情况导出了描述粘塑性流体在旋转圆盘上流动的基本方程。

The equations describing the flow of a viscoplastic fluid on a rotating disk are derived and are solved by perturbation technique and numerical computation respectively for 2 cases.
