hard segment meaning in Chinese

硬链段

The result showed that with increasing of hard segment content , the crystallinity of copolymer increased , thehard se gment content and the molecular weight of polyether were influence on the mechanical properties of copolymers
结果表明，共聚物的结晶度随聚酯硬段含量的增加而增加，而其力学性能则受聚酯硬段含量和聚醚分子量的影响。
It was found that the high , ystallinity of the soft segment regions and the formation of hard segment domains are the necessary conditions for polyurethane with good shape memory behavior . secondly , shape memory polyurethane ionomer was synthesized
并从结构与性能的关系入手，深入探讨了形状记忆聚氨酯的结构对其形状记忆性能的影响，发现软段高度结晶和硬段聚集形成硬段微区是聚氨酯具有较好形状记忆性能的必要条件。
