A general neutron breeder formula considering one group delayed neutron;

考慮單群緩發(fā)中子時(shí)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(zhǎng)計(jì)數(shù)器測(cè)量已知裂變率的緩發(fā)中子計(jì)數(shù)率,然后用同一探測(cè)系統(tǒng)測(cè)量脈沖后的緩發(fā)中子計(jì)數(shù)率,探測(cè)系統(tǒng)的探測(cè)效率、緩發(fā)中子份額和緩發(fā)中子先驅(qū)核半衰期等參數(shù)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(shù)的方法。

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

通過對(duì)14 1MeV脈沖中子源和產(chǎn)生的緩發(fā)中子在模型中的輸運(yùn)計(jì)算,分析了用脈沖外中子源產(chǎn)生的緩發(fā)中子探測(cè)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(nèi)翻畸形動(dòng)物模型。
