緩發中子核 的英文怎麼說
中文拼音 [huǎnfāzhōngzihé]
緩發中子核
英文
delayed neutron kernel-
If using the natural uranium to replace the heu pit in warhead, the delayed neutron counting rate would be about 3 times lower. the coincidence neutron detection is proposed to be used in nuclear warhead detection
計算表明用天然鈾替代高濃鈾作的假彈頭，它們的出殼緩發中子數相差約3倍，需在一定條件下，才可對真偽核彈頭做出判斷。Detecting nuclear warhead by counting delayed neutrons induced by neutron source is studied. the 2 - step calculation method is proposed to resolve the delayed neutron transportation issue. this method can save computer ' s calculation time, and is easy to operate
本文研究了用外中子源照射核彈頭，誘發其裂變材料裂變，探測緩發中子的方法，以此判斷高濃鈾與低濃鈾，從而為核查核彈頭的真偽提供依據。The sutdy on technique of measuring fission, delayed neutrons from uranium materials and the method of distinguished nuclear from non nuclear materials with the active method are described
用主動方法研究了核材料鈾的裂變緩發中子測量技術和區分核與非核材料的方法。
