在匹配两组儿章非语言智龄(以知觉—操作分量表的得分标示)的基础上，比较了两组儿童被试在语言障碍评量表、听力短时记忆测试、视觉短时记忆测试中的表现，并对男、女唐氏儿章在语言障碍评量表的得分情况进行了分析，经过统计分析得出了下列5个结论：Ⅰ。

The results showed that PPC was a thermotropic liquid crystal and displayed the cholesteric banded texture. The reaction conditions had the distinct effects on the propoxy content and liquid crystal property of PPC, with the reaction temperature and content of propionyl chloride increased, the degree of substitution of propoxy increased at the beginning, then trended to steady. The transition temperature and range of liquid crystalline phase were changed with the DS of propoxy, as the DS of propoxy increased, the melt point decreased, and the liquid crystalline phase transition temperature range of PPC get wider.
