摘　　要：介绍了用于柴油机缸内燃烧的几种光学测试方法 ,对其中技术上较为成熟的两种方法——透射光衰减法和双色法的基本原理以及优缺点进行了讨论 ,指出光学测试方法的优越性在于 ,通过图像分析可以得到燃烧场的二维或三维信息 。Several optical methods for detecting particulate in the combustion chamber of diesel engines are introduced,specially,two of them,Two-Color Method,Transmitted Light-Attenuation Method which are feasible in technology are discussed in detail. The advantage of the optical detecting methods is pointed out, a two-dimension(or three-dimension) information rather than the information of a few dots in the combustion field can be obtained by means of the technique of the picture analysis.
