threshold energy造句
例句与造句
- If the incident proton collides with a proton bound in a nucleus, the threshold energy is lower because the target proton is bound .
如果入射质子是与束缚在原子核内的质子相碰撞，那么阈能会低一些，因为作为靶的质子是束缚着的。 - It was found that the simple triangular shape distribution would cause " two - peaked " energy distribution near the threshold energy , which must affect the group transfer matrix
阈能处三角形能谱分布的近似描述，导致产生了群散射矩阵的“双峰”现象，而阈能处矩形能谱分布使平均次级中子能量( - The relative momentum of two final particles and the cross section are zero at the threshold energy for an endothermic reaction , while the relative momentum of two initial particles is zero and the cross section at the threshold energy for an exothermic reaction is infinite
