例句與用法

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
推導并提出用中子輸運計算與概率方法結(jié)合計算符合中子計數(shù)，對能量低于1mev的外源中子照射核彈頭誘發(fā)裂變的符合中子測量作了數(shù)值模擬。
In analyzing the neutron active detection , the neutron multiplication in the nuclear warheads induced by outer neutron source with different neutron energys is studied with numeral simulation , and the feasibility of through counting neutrons to determine the presence of high enrichment uranium ( heu ) in nuclear warhead has been proved . the method of detecting the warhead which contains heu pit by counting the released neut rons whose energy is higher than that of source neutron is studied . the feasibility of this method has been studied
對幾種主動探測核彈頭方法進行的研究中，首先對不同能量各向同性外源中子照射核彈頭的中子增殖行為進行了數(shù)值模擬，檢驗了用外源中子照射核彈頭后，通過測量瞬發(fā)中子在核彈頭中的增殖量，來證明核彈頭中高濃鈾存在的可行性；研究了用能量低于1mev的外中子源照射核彈頭，用測量核彈頭中裂變產(chǎn)生的高于源中子能量中子數(shù)的方法探測核彈頭，通過數(shù)值模擬分析了可行性。
The measurement data is scarce in 8 - 13 mev region due to the lack of mono - energetic neutron sources ( in this region , there are breakup neutrons besides the mono - energetic neutrons in the often used neutron sources such as t ( p , n ) 3 he and d ( d , n ) 3he sources . the secondary neutrons induced by breakup source neutrons will seriously contaminate the secondary neutron spectra induced by mono - energetic source neutrons ) . therefore , precise measurement for some key nuclides is necessary to check the evaluations in this region
但在8 ? 13mev這一能區(qū)，由于沒有合適的單能中子源(因為在這一能區(qū)，對于常規(guī)中子源如t ( p , n ) ~ 3he和d ( d , n ) ~ 3he中子源，除了單能中子以外，還有破裂中子成份，這部分源破裂中子在樣品上引起的次級中子，將嚴重影響測量結(jié)果) ，所以至今在8 ? 13mev能區(qū)這方面的測量數(shù)據(jù)極少。
