摘　　要：粒子系统在描述自然景物中具有很大的优势,建立一种简单有效可扩展的粒子系统构造方法是必要的。方法:通过分析北卡罗来纳大学开发的粒子系统API函数库(API for Particle Systems)功能以及接口,在此基础上构造了几种常见的粒子系统。结果:在该函数库基础上进行适当扩展或将其它方法(如纹理贴图)与其相结合构造具有较强真实感与实时性粒子系统是一种简单有效的方法。Purpose： To set up a simple and effective method easy to be extended to construct particle system is necessary, since particle systems have great advantage in describing natural scenery. Methods： The function and interface was analysed for the particle system API library which was developped by the University of North Carolina, and several particle system examples were constructed based on it. Results： This method is a simple and effective method to construct particle system with realistic effect in real-time on basis of the library with appropriate extension or using other methods（for example, texture mapping）.
