The quantity of propellant flame soot was characterized with the light transmission including the laser transmission and the visible light transmission, the computed temperature in theory was chosen as the relative standard temperature of CARS temperature, and the value of CARS temperautre was compared with that measured by a thermocouple technique.

采用透过率(激光透过率、可见光透过率)表征推进剂火焰烟尘的量,以理论计算温度作为CARS(CoherentAnti-StokesRamanSpectrometry)测温的相对标准温度,并将测得的CARS温度与热电偶温度进行了对比。
