裂变中子 meaning in Chinese

fission neutrion
fission neutrons
fission-neutron

In addition, somewhat less than 1 percent of the fission neutrons, called the "delayed" neutrons, are emitted subsequently .
此外，还有一些约少于1的叫做“缓发”中子的裂变中子，随后被发射出来。
The total shielding effects of the materials with certain thickness for fission neutron and - ray are all much better than iron , and the equivalent masses are lower than iron at same shielding effect
结果表明：在达到一定厚度后，这些材料对裂变中子、的总屏蔽效果均超过铁，且相同屏蔽效果下的铁质量当量显著下降。
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。
