In order to set up the technical system of transplanting and taming prawn into alkaline waters in northeast China,to make growth experiment of juvenile Litopenaeus vannamei by way of semi-saltwater from prawn pond and the water of alkaline lake,researching the relativity between the growth of juvenile shrimp and 10 kinds of environmental factors.

Correlation between growth rate of prawn in body weight and Ca~(2+) and Mg~(2+) in alkaline waters to the Songnen Plain in China;

In order to research the techniques of prawn culture in alkaline waters,it\'s needed to study the relativity between the survival and growth of prawn and the mass concentration of K+,Ca2+ and Mg2+,Na+/K+ and M/D ratio(ionic coefficient) in alkaline water environment,by means of growth test of Litopenaeus vannamei with the water of saline-alkali lake and pond.

To understand the feasibility of transplanting prawn in carbonate saline-alkali waters,acute toxicity of the alkalinity to desalination larval Penaeus vannamei was determined in wild by one-way toxicity test,and to survey the live ability of desalination larval P.

It was proved that alkali wastewater can be treated by microelectrolysis.

Synthesis of glycolic acid monomer by chloroacetic acid alkaline hydrolysis method;

Studies on kinetics of alkaline hydrolysis of PNPA catalyzed by micelles;

Effects of micelles of the cationic surfactantCTAB,the animic surfactant LAS and the nonionic surfactant Tween80 on the alkaline hydrolysis of iso-amyl acetate have been studied at 35℃and 45℃.
