So here we will take the way of the Equal Channel Angular Extrusion (ECAE) to process poly (d, L-lactide) to improve its properties.

本研究采用等通道转角挤压技术对聚(d, L -)乳酸进行自增强研究，并测试其增强后的降解性能。

Fibrous tissue formed by extrusion is the main reason of the anisotropy in L and LT directions.

挤压形成的纤维组织是引起挤压带板L向及LT向各向异性的主要原因。
