Which is the steady state approximation, where one rate, the rate to go into the intermediate is very slow, or the rate to get out of the intermediate is very fast.
它是稳态近似，其中一个速率，生成中间产物的速率十分缓慢，或用掉中间产物的速率十分快。

In the framework of the distorted wave approximation, we discuss the differential cross section and polarization of antiproton-nucleus inelastic scatterings at intermediate energies.
