Abstract: Based on Moliere expansion potential, the equation of particle motion has been reduced to the nonlinear differential equation and looked for the solution of the equation by PLK method. Nonlinear properties of this system are discussed and the space dstribution and the momentum distribution of channeling particle are denied.

摘要： 本文利用Moliere展开势,将粒子运动方程化为非线性微分方程;并用PLK方法找到了该方程的近似解析解;进一步讨论了系统的非线性特征,导出了沟道粒子的空间分布和动量分布。
