delayed particle

A general neutron breeder formula considering one group delayed neutron;

考慮單群緩發中子時中子增殖的統一公式

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.

用長計數器測量已知裂變率的緩發中子計數率,然后用同一探測系統測量脈沖后的緩發中子計數率,探測系統的探測效率、緩發中子份額和緩發中子先驅核半衰期等參數均不變,從而建立起利用脈沖堆脈沖后的緩發中子衰減曲線確定脈沖裂變總數的方法。

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

通過對14 1MeV脈沖中子源和產生的緩發中子在模型中的輸運計算,分析了用脈沖外中子源產生的緩發中子探測核彈頭的可行性。

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

目的　建立緩發型肘內翻畸形動物模型。
