In our research on study chemical reaction of active methylene compounds and brom-acetophenone. Because of brom-acetophenone is compound that contain carbonyl and halogen ,which will take place electrophilic substitution and nucleophilic addition. When active methylene compounds are ethyl acetoacetate and β-diketone, controlling reaction condition, we have found that mono-substitution's production and di-substitution's. production is isolated; active methylene compounds are acetoacetanilide and acetoacetanilide derivate, pyrrolidin-2-one derivants were obtained by substitution and close-ring reaction .but there is no report about it.

本文是让活泼亚甲基类化合物与溴代苯乙酮发生化学反应，由于溴代苯乙酮是含有羰基的卤代烃结构，它可以发生亲电取代和亲核加成反应，当活泼亚甲基类化合物为乙酰乙酸乙酯和β-二酮时，控制反应条件可以发生单取代和双取代两种产物；当活泼亚甲基类化合物为乙酰乙酰芳胺类化合物来反应时，溴代苯乙酮中的羰基与氨基会发生分子内的关环反应生成吡咯烷-2-酮衍生物，这在以前的研究中是没有发现的。

The effects of the mechanism on both the efficiency of options investment and on the substitution of the incentive mechanism are analyzed. These substitution effects involve two aspects: the complete substitution to efficiency of investment exercising and the partial substitution to information rents.

重点分析了审核机制对投资期权执行效率的影响以及对激励机制的替代作用，这种替代作用表现为在投资执行效率方面的完全替代和在信息租金方面的部分替代。

It is the most powerful means of eradicating schistosomiasis. Current method of elimination cercaria is mainly the chemical method which has many disadvantages such as drug resistance, drug dilutedness, environmental pollution and poisoning the other biology, etc. For these reasons, this paper poposed a new method of elimination through high-voltage pulsed electric field, discussed the feasibility of the new method, studied the elimination mechanisms of using different forms of electrodes, analyzed various factors which influences the effect of elimination and introduced the structure of high-voltage pulsed electric field system at the stage of laboratory. Moreover, this paper showed the security problems that should be considered during the research and experiment.

针对常用的化学药物杀灭法存在的易使尾蚴产生抗药性、水域宽广致使药效降低、污染环境、毒杀其它生物等弊端，本文提出了一种利用高压脉冲电场杀灭血吸虫尾蚴的新方法，探讨了这种电子杀灭方法的可行性，分别研究了采用锐形电极和平板电极的血吸虫尾蚴杀灭机理，分析了影响尾蚴杀灭效果的各种因素，介绍了实验阶段血吸虫尾蚴高压脉冲电场杀灭系统的构成，指出了系统研制和试验过程中需要充分考虑的安全性问题。
