neutron detection meaning in Chinese
中子探测
Examples
- 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
计算表明用天然铀替代高浓铀作的假弹头，它们的出壳缓发中子数相差约3倍，需在一定条件下，才可对真伪核弹头做出判断。 - In numeral simulation of passive neutron detection , it is proposed to use the iterative calculation in analyzing the neutron multiplication in nuclear warhead . on this basis , the mass of the plutonium pit could be obtained under some conditions
在被动中子探测数值模拟中，提出在确定了核弹头的泄漏中子计数后，采用迭代方法计算中子在核弹头模型中的增殖，由此在一定条件下可实施核弹头质量属性的反演。 - The method of numeral simulating the coincidence neutron detection is proposed with combining the neutron transportation and probabilistic calculation . the method is introduced and used to simulate the nuclear warhead induced fission by source neutrons with energy below 1 mev
推导并提出用中子输运计算与概率方法结合计算符合中子计数，对能量低于1mev的外源中子照射核弹头诱发裂变的符合中子测量作了数值模拟。 - The results show that coincidence detection method has obvious benefit in detecting nuclear warheads . for the same type warhead , the coincidence counts rates of the model of warhead of heu pit is 10 times as big as that of fake warhead of natural uranium pit . if we know the nuclear warheads configuration by other methods , the method of coincidence neutron detection could be used to distinguis h the fake nuclear warheads from the reals
计算表明用探测符合中子的方法探测核弹头对区分真假核弹头有明显的优点，对于同一核弹头模型，裂变弹芯是高浓铀和用天然铀替代高浓铀时，符合中子计数相差1个量级，如通过其他途径了解核弹头的大致结构，符合测量的方法就可以有较高的置信度分辨真假核弹头。
