The misshapen cells lack plasticity and can block small blood vessels, impairing blood flow.
畸形细胞缺乏可塑性，会阻塞毛细血管，阻碍血液流动。

Based on the crystal plasticity theory and mathematical theory of statistics, the relation of flow stress fluctuation quantity to grain dimension as well as billet dimensions was built.
基于晶体塑性理论及数理统计理论，建立了流动应力波动幅度与晶粒尺寸和坯料几何尺寸间的关系。

We discuss the dynamics problems of ideal rigid-plastic material in the flow theory of plasticity in this paper.
