高分子由于分子链比较长，分子运动比较缓慢，常以亚稳态形式存在。近年来随着亚稳态理论［１］在高分子科学中得到不断拓展，已成为高分子物理的一个重要研究方向，最近Ｋｅｌｅｒ［２］发现ＰＥ结晶尺寸厚度对晶体结构有重要影响，在结晶尺寸厚度较小时，ＰＥ以六方晶型...
As the molecular chain longer polymer, molecular movement is relatively slow, often exist in metastable form. In recent years, with metastable state theory [1] in the polymer science has been expanding, has become an important research direction of polymer physics, Keler [2] recently found that PE crystal size and thickness of the crystal structure has an important impact on the crystallization When the size of the smaller thickness, PE hexagonal ...
