| 摘 要： | 迄今为止,人们只分别导出了深度次临界、缓发临界附近和瞬发超临界的几个特定条件下的中子增殖公式,各公式都不具有通用性,使用很不便.文中导出了反应性阶跃变化时,只考虑单群缓发中子从深度次临界直到缓发超临界整个区间上的中子增殖统一公式.实例计算表明,该公式计算准确,实用性强,具有重要的理论意义与应用价值.

| Abstract: | At present, the formulas in the deep below critical, near delayed critical and prompt supercritical conditions are developed separately. The calculation is difficult without a general formula. Thus, a general neutron breeder formula which can be applied to all the conditions (from the deep below critical condition to prompt supercritical condition) is developed when the reactivity changes in phase and only one group delayed neutron is considered. At last, the correctness and applicability of the formula are verified by an example. |
