模耦合理论比较成功地解释了微波不稳定性的发生 ,其理论基础是Vlasov方程 .Fokker Planck方程包含了束团的辐射阻尼效应和量子激发效应 ,是比较完备地描述粒子运动状态的束团分布方程 .比较了Fokker Planck方程和Vlasov方程在来源、意义和解法方面的关联和不同 ,同时介绍了一种多项式展开束团耦合模式来求解Fokker Planck方程的方法 ,并在静态分布中包含了势阱畸变的效应
The theory of mode coupling successfully explains the microwave instability, the theoretical basis of which is the Vlasov equation. The Fokker Planck equation contains the radiation damping effect and the quantum excitation effect of the bunched mass. It is a relatively complete description of the bunched mass distribution The relationship between the Fokker Planck equation and the Vlasov equation in terms of source, meaning and solution is compared, and a polynomial method for solving the Fokker Planck equation is introduced, and the potential distribution is also included in the static distribution Distortion effect
