delayed particle

A general neutron breeder formula considering one group delayed neutron;

考虑单群缓发中子时中子增殖的统一公式

Based on the comparison of the delayed neutron counter rate of known fission rate with the delayed neutron counter rate of a burst,a method to determine burst total fission number of burst reactor was built.

用长计数器测量已知裂变率的缓发中子计数率,然后用同一探测系统测量脉冲后的缓发中子计数率,探测系统的探测效率、缓发中子份额和缓发中子先驱核半衰期等参数均不变,从而建立起利用脉冲堆脉冲后的缓发中子衰减曲线确定脉冲裂变总数的方法。

With 141 MeV pulse neutron source,distribution of delayed neutron flow with time is studied.

通过对14 1MeV脉冲中子源和产生的缓发中子在模型中的输运计算,分析了用脉冲外中子源产生的缓发中子探测核弹头的可行性。

S OBJECTIVE:To construct an animal model of delayed cubitus varus.

目的　建立缓发型肘内翻畸形动物模型。
