  1. 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值模擬，檢驗了用外源中子照射核彈頭后，通過測量瞬發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；研究了用能量低於1mev的外中子源照射核彈頭，用測量核彈頭中裂變產生的高於源中子能量中子數的方法探測核彈頭，通過數值模擬分析了可行性。
  2. None of the xenon isotopes we measured were the direct result of uranium fission

    我們所測量到的氙同位素，根本都不是直接由鈾的核分裂而來。
  3. The author and two colleagues recently used measurements of xenon gas ( a product of uranium fission ) to deduce that one of these ancient reactors must have operated with a duty cycle of about half an hour on and at least two and a half hours off

    作者與兩位同事最近透過氙氣（鈾的核分裂產物）的測量推測，這些遠古反應器其中之一必定曾經以運作半小時、關閉兩小時半的周期進行核反應。
  4. Three decades ago french scientists discovered that parts of a uranium deposit then being mined in gabon had long ago functioned as natural fission reactors

    30年前法國科學家發現，當時正在開採的加彭鈾礦中，有某些部份在很久以前曾經是天然的核分裂反應堆。
  5. In addition to splitting the nucleus into two halves, the process releases two or more neutrons and a large amount of energy in the form of heat. the released neutrons in turn hit more uranium nuclei and release more neutrons to produce a chain reaction

    核裂變過程除了把原子核分裂成兩份外，亦會釋放大量的熱能及同時放出兩個或以上中子，以撞擊更多鈾原子核，再釋放更多中子，產生鏈式裂變反應。
  6. 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

    計算表明用探測符合中子的方法探測核彈頭對區分真假核彈頭有明顯的優點，對于同一核彈頭模型，裂變彈芯是高濃鈾和用天然鈾替代高濃鈾時，符合中子計數相差1個量級，如通過其他途徑了解核彈頭的大致結構，符合測量的方法就可以有較高的置信度分辨真假核彈頭。
  7. Pu - 239 would produce fission in the reactor in the same way as u - 235 and contributes in supplying part of the energy for power generation

    ? - 239亦是易裂變的核素，會像鈾- 235一樣，在反應堆中產生裂變，供應部分能量以供發電。
  8. Kuroda ' s first condition was that the size of the uranium deposit should exceed the average length that fission - inducing neutrons travel, about two thirds of a meter

    黑田和夫推測出的第一個條件是，鈾礦床的大小，必須超過核分裂所產生的中子所移動的平均長度，約為2 / 3公尺。
  9. Nuclear fission is initiated when the nucleus of a uranium atom is hit by a neutron and split into two halves

    鈾原子核被中子撞擊后，會分裂成兩份，產生核裂變。
  10. 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。
