摘　　要：空间太阳能电站的大功率微波波束穿过电离层时可能发生一系列线性和非线性过程。非线性过程往往更为复杂和难以预测,文章主要介绍比较重要的受激Brillouin散射,受激Raman散射和热自聚焦不稳定性等3种非线性作用。结合空间太阳能电站系统参数给出一些计算结果,可以为系统设计提供初步依据。A series of linear and nonlinear process would occur when the high power microwave beam of solar power satellites （SPS） propagates through the ionosphere. The latter may be much more complex and predictable. Three of them, say stimulated Brillouin scattering, stimulated Raman scattering and thermal self-focusing instability, are introduced. Some computed results are presented referring to system parameters of SPS,which may serve as primary principle of system design.
