Another important kind of interferences in reactor NAA is due to threshold reaction induced by reactor fast neutrons.
在不同实验系统上，测量了铁球壳表面不同位置上中子引起的绝对裂变反应率分布。
In different experiment systems, absolute fission reaction rates, derived from reflection neutrons, at different positions of the surface of an iron spherical shell were measured.
并用MCNP程序模拟了在高压倍加器的实验条件下的散射中子能谱，进而计算了低能散射中子引起的修正量。
The incident neutron spectrum at the experimental condition has been simulated with the code MCNP, and the scattering neutron influence has been calculated with the spectrum.
中子星的大小是受限的——若它们的质量超过了一个特定的界限，重力就会引起进一步的坍塌并形成黑洞。
Neutron stars are restricted in how massive they can be ? if they weigh over a certain limit, then gravity would have collapsed the object further into a black hole.
最终中子恒星中暗物质恒星的质量会超过它的“钱德拉·塞卡极限(Chandrashekar limit)——超过了这个极限值，一个恒星就经受不住引力所引起的压力。”
Eventually, the mass of the dark matter star would exceed its "Chandrashekar limit" - beyond which a star cannot withstand gravitational pressure.
分析表明，中子辐照脆化、腐蚀损伤、疲劳及磨损引起核电厂不可更换部件及更换困难部件的老化、降级是制约或极大程度影响电厂寿命的关键问题。

中子辐照引起的核反应堆压力容器钢中磷的晶间偏析是导致核反应堆压力容器脆性断裂的主要因素之一。
Neutron irradiation-induced phosphorus intergranular segregation in the reactor pressure vessel steels is the one of main reasons resulting in brittle fracture of the nuclear reactor vessel.
按此模型，引起的突然压缩和随后的爆发会把恒量的外部包层吹跑，留下的核成为一颗中子星。
In this model, the resulting implosion and ensuing explosion would blow off the outer envelope of the star and leave behind the core as a neutron star.
