neutron energy group的意思|示意

And you can do it in one-group theory or multi-group theory. One-group theory assumes that the neutron energy and everything is going on at one energy and we have to make some adjustments.

你能够在单群理论或这多群理论里，单群理论假设，中子能量和所有的东西，要达到一个能量，我们必须要做出些调整。

Neutron shielding factors of the foil are calculated for each group in intermediate energy range with detail consideration of cadmium filter and scattering by the foil itself.

考虑镉的屏蔽和探测箔的自身散射影响后的屏蔽，求出每一种探测箔在中能区各群的中子屏蔽因子，从而求得有效活化反应截面。

The spacing of Ir is probably somewhat over estimated since the values of the energy and absorption coefficient of the resonance neutron group, used in the estimation, are not very accurate.

因计算时所用共振中子之能及吸收系数不太准确，估计所得铱之间隔大概过高。
