And if you scatter you can have an elastic scattering cross section or an inelastic scattering cross section which are combined to the fundamental scattering cross section.

如果你们有一个弹性散射，横截面或非弹性散射横截面，那是结合成基本的散射，横截面。

It is shown that a phase variation of the nucleon-nucleon elastic scattering amplitude leads to a large increase in the calculated differential cross-section and a substantial improvement.

计算结果表明核子-核子弹性散射的位相变化使理论微分截面增大，改进了理论值与实验数据的符合。
