摘　　要：针对空战视景仿真中不规则现象模拟这一难点,依据粒子系统基本原理,定性和定量相结合分析了Vega自定义特殊效果模块参数的数值含义,提出了量化粒子系统参数的方法。以空战视景仿真中常见的燃烧、爆炸效果仿真为例对参数的综合使用进行了系统设置,采用量化参数的方法得到相应模拟效果的参数范围,最后进行仿真模拟逐次逼近得到最优参数,仿真结果证明了量化参数的合理性。In order to solve the problem of anomalous phenomena simulation in the aerial warfare scene simulation, according to the basic principles of Particle System, the meaning of custom parameter′s value in Vega is analyzed in a qualitative and quantitative way. Thereby, the numeric method of setting the parameters for particle system is put forward. Taking burning and exploding effects for example, which is familiar in the aerial warfare scene simulation, the parameters are set synthetically. After getting the range of parameters of simulation effect by the numeric method, the most optimized parameters are gained by simulation time after time. The simulation results prove that the numerical method is reasonable.
