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。By measuring high - fold prompt - ray coincidence events following the spontaneous fission of 252cf, the high spin states in very neutron - rich 113ru nucleus have been studied. furthermore, some isomers in neutron - rich odd - a nuclei 107 ， 109 ， 111 ， 113ru have been analyzed
通過對252cf自發裂變產生的瞬發譜的測量，對極端豐中子核113ru的高自旋態進行了研究，並對豐中子奇a核107 ， 109 ， 111 ， 113ru的低激發態同質異能態進行了分析。The fds ( fusion - driven sub - critical system ) can realize the transmutation of hlw ( high level waste ), fuel production, energy breeding and tritium production by utilizing the external neutron source to make the reactor operated under the sub - critical state
聚變中子源驅動的次臨界核能系統（ fds ）是根據聚變和裂變反應的各自特點，利用外源中子進入包層的次臨界系統，實現增殖燃料、增益能量、產氚和嬗變核廢料等功能。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。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。U - 238 can induce fission after absorbing a high energy neutron fast neutron and then forming the plutonium 239 pu - 239, which is a fissile nuclide
后極可能產生裂變的核素，鈾- 238則是可裂變的核素。鈾- 238在吸收高能量的中子快中子后，會形成- 239 pu - 239 。With the outer neutron source which can only induce 235u fission, it could possibly prove the presence of heu in a warhead by counting the coincidence neutrons. this method possibly provides one of necessary attributions in identifying the real nuclear warheads
本文研究了用中子符合探測方式測量能量低於1mev的外中子源在核彈頭中誘發的裂變數，以判別模型中是否含有高濃鈾，從而作為判斷核彈頭的真偽的可行性。The high energy neutrons released by fission travel at very high speeds fast neutrons and must be slowed down to increase its probability of hitting more uranium atoms and in turn induce more fission in the reactor
核裂變所釋放的高能量中子移動速度極高快中子，因此必須透過減速，以增加其撞擊鈾原子的機會，同時引發更多核裂變。The high energy neutrons released by fission travel at very high speeds ( fast neutrons ) and must be slowed down to increase its probability of hitting more uranium atoms and in turn induce more fission in the reactor
核裂變所釋放的高能量中子移動速度極高（快中子） ，因此必須透過減速，以增加其撞擊鈾原子的機會，同時引發更多核裂變。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
推導並提出用中子輸運計算與概率方法結合計算符合中子計數，對能量低於1mev的外源中子照射核彈頭誘發裂變的符合中子測量作了數值模擬。分享友人
