本文中的调查显示，复数的三角形式是学生认知的难点，我从以下四点分析了对学生学习三角形式的影响：（1）三角比、三角公式对复数三角形式认知的影响；（2）复数三角形式的学习是学生对复数认知的重组和深化；（3）老师的信念和高考对学生学习复数三角形式的影响；（4）教材体系的编排对学生学习复数三角形式的影响。

The catalysts such as tetraphenyl tin,aluminium isopropoxide and boron trifluoride etherate complex were used to catalyze the copolymerization.In addition,the copolyester can be given by copolycondensation after monomers were hydrolyzed by phosphoric acid.Boron trifluoride etherate complex was chosen as the catalyst because the catalytic activity was the best among the catalysts.

由于γ-戊内酯为五元环结构，难以进行开环聚合，因此分别考察了四苯基锡、异丙醇铝、三氟化硼乙醚络合物等催化剂，以及以磷酸为催化剂的水解缩聚反应，结果发现三氟化硼乙醚络合物的催化活性最高，因此选择三氟化硼乙醚为本体开环聚合的催化剂。
