摘　　要：为了在基于PIC方法编制的粒子模拟软件CHIPIC上添加永磁体模拟模块,在永磁体面磁荷模型理论基础上结合磁场边界条件,利用泰勒公式推导出一种关于永磁体计算新的差分格式,用自编制永磁计算模块实现了对永磁体的磁场分布计算。将模拟结果与理论计算值进行对比,其结果表明,模拟计算结果与理论计算结果符合得很好,证明了本数值方法的实现正确性。The simulation module of permanent magnet is added on the particle simulation software CHIPIC,which is based on the PIC method.Combined the surface magnetic charge model with the boundary condition of magnetic field,a new difference scheme about three-dimensional permanent magnet calculation is derived by Taylor formula,and the magnetic field distribution of permanent magnet is calculated.Finally the calculated value and theoretical value are compared,and the result is verified correctly.
