But if we want to make it work normaly and make it work with electronic development to distinguish the neutron ' s inelastic scattering y spectra with the capture spectra , then we can get the element ' s inelastic scattering y spectra , we must research again the controlled circuit of the pulse neutron generator 而要使脉冲中子发生器正常工作并且能于我们自己研制的电控门配合,将中子与物质中所含元素的原子核相互作用的非弹性散射反应和俘获反应区分丌来,从而得到能够较好的表征该元素的非弹性散射谱。
