scattering angular distribution造句

All cross sections of neutron induced reaction , elastic scattering angular distribution , neutron energy spectrum and double differential cross sections were calculated by using optical model and the semi - classical model of multi - step nuclear reaction processes based on the hauser - feshbach and exciton model in the energy region up to 20mev
应用光学模型和以复合核平衡态理论( hauser ? feshbach理论)及激子模型为基础的核反应多步过程的半经典理论，计算了当中子入射能量低于20mev时n + ~ ( 112120 ) sn反应的所有中子入射截面、弹性散射角分布、出射中子能谱以及出射中子双微分截面。
