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。

The experiment studied the effects of applying different amount of B and Zn to peanuts growth, development and yield. The results showed that by supplying rational micro-fertilizer of Boron and zinc, the growth and development of the first pair cotyledonary branch, root nodules leaves and pods could be promoted, the yield was significantly increased on the basis of supplying rational Nitrogen, Phosphorus and Potassium. In this experiment, supplying Boron 7.5 kg/hm^2 and 11.25 kg/hm^2 could increase by 6.87% and 8.19% in comparison with CK, supplying Zinc 7.5 kg/hm^2 and 11.25 kg/hm^2 could increase by 7.17% and 5.20% in comparison with CK.
