A general neutron breeder formula considering one group delayed neutron;
考慮單群緩發(fā)中子時中子增殖的統(tǒng)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(fā)中子計數率,然后用同一探測系統(tǒng)測量脈沖后的緩發(fā)中子計數率,探測系統(tǒng)的探測效率、緩發(fā)中子份額和緩發(fā)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(fā)中子衰減曲線確定脈沖裂變總數的方法。
With 141 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(fā)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(fā)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(fā)型肘內翻畸形動物模型。
