induced fission meaning in English

强迫分裂
诱导裂变
诱发裂变
诱生裂变

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
后极可能产生裂变的核素，铀- 238则是可裂变的核素。铀- 238在吸收高能量的中子快中子后，会形成- 239 pu - 239 。
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 simulation can be divided into three processes sequentially : calculating the induced fission neutron rate of uranium and space distribution by mam - li neutron source , computing the total uranium fission neutron count rate and time distributions of 42 3he tubes , and calculating the neutron coincidence counting rate
第一步，以ain ? li源为中子源，计算铀的诱发裂变中子产生二率及空间分布；第二步，以铀的诱发裂变中子为中子源，计算化根’ ne管的总中子计数率及时间分布；第三步，计算中子符合计数率。
