粒子逃逸

在DDPSO算法基础上，基于人工免疫（ArtificalImmune，AI）原理，设计了粒子逃逸算子和群体排斥算子，通过检测粒子个体和群体浓度改变粒子运动轨迹，以保持个体和群体的多样性。

Escape operator and repulsion operator based on artifical immune ( AI ) theory are proposed , which can keep the diversity of particle swarm by checking the density of particle individuals and swarm to change particles tracks .

试验结果表明，外加磁场B制约了带电粒子逃逸出电极空间，提高了反应气体的离化率及等离子体浓度和活性，并使非独立变量Pf和Uz成为独立变量，有利于工艺调节。

The results showed that the introduced magnetic field B restricted the charged particles from escaping from electrode space , so the ionization degree of the reaction gases , the plasma density and the plasma activity were increased .
