The application of polar coordinates system in the CNC LATHE-MILLING;2. A fast particle-moving algorithm for particle-in-cell simulation of plasmas in polar coordinates system was proposed, in which the local rectangular coordinates approximation was used in the area near the position of the charged particle at every time step.

提出了一种在极坐标系下快速推进带电粒子的等离子体粒子模拟算法，该算法在每个时间步长内对带电粒子位置附近的区域采用局部直角坐标系近似，并通过坐标变换，得到粒子运动方程求解的显式格式，从而避免了极坐标系下隐式格式直接迭代求解所带来的容许误差，并提高了计算效率。
