摘要
通过实例计算首次提出点堆中子动力学方程、中子按代倍增公式和三维两群扩散方程在一定的反应性变化下存在反应性大于零时功率减小的现象,并指出该现象的普遍性。根据有效增殖因子的物理意义,指出导致这种不同步现象的根本原因。对点堆方程给出了符合物理意义的有效增殖因子新定义,同时给出了新的点堆中子动力学方程。
The asynchronous phenomenon was shown through examples for the first time.The universality of the asynchronization was pointed out.The basic cause was found to be the improper definition and application of the effective multiplication factor（keff）.The new definition of keff for the point reactor neutron kinetics equation（PRNKE） was given and verified by an example.The new PRNKE was also offered.
