摘　　要：设计了柴油机排气模拟系统 ,利用该系统准确、经济地测试了壁流式蜂窝陶瓷过滤体和泡沫陶瓷过滤体的阻力特性 ,得到了一些定性的规律 ,可为过滤器的过滤材料选型提供参考。A diesel engine exhaust simulating system is designed. The resistance characteristic of ceramic wall-flow filter and ceramic foam filter has economically been measured by using that system with high accuracy. Some qualitative rules of resistance characteristic have been found, which offer evidence of the choice of filter medium.
