摘　　要：本文叙述了点堆动力学方程的两种改进解法,即反应性限制法和综合法。这两种方法分别比赫米特(Hermite)插值多项式法和国外全尺寸模拟器上所采用的变量隐含积分(Variablelmplicit Integration)法具有更高的精确度和更短的计算时间。Two improved solution methods of point reactor kinetis equations,reactivity confinement method and comprehensive method are described inthis paper.The two methods are more accurate and have less computat-ion time than Hermite Interpolating Multinomial method and variableimplicit integration method which is adopted in full scope simulators ab-road.
