摘　　要：给出了在中能区(≤250 MeV)多次粒子发射过程中计算6种出射轻粒子(n,p,α,d,t,~3He)及各种反冲核之能谱和双微分截面的方法.对p+^(208)Pb反应给出了发射中子能谱和双微分截面的部分计算结果与实验数据的比较.The methods to calculate the energy spectra of six kinds of emitting light particles （n, p, a, d, t, ^3He） and all kinds of recoil nuclei as well as the double differential cross sections of these six kinds of particles for medium-heavy nuclei with the same six kinds of particles as projectiles in the energy region up to 250 MeV are given in this work. And parts of the calculated results of energy spectra and double differential cross sections of emitting neutrons for p＋^208 Pb in comparison with experimental data are also given.
