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。

This article has sorted out the data of indefinite integral concept in common use, and has analyzed the features of three methods of indefinite integral in common use: the first substitution method of integration, the second substitution method of integration, and integration by parts.

因为，(x2)′=2x，(x2+1)′=2x，(x2+2)′=2x，(x2+c)′=2x所以x2，x2+1，x2+2，x2+c均为2x的原函数。由此得出：一个函数若有原函数存在则有无数个原函数存在，且任意两个原函数之间相差一个常数。
