一)测量高速高温气流的温度所存在的几个问题 目前喷气发动机一般采用炭氢化合物作力燃料(个别也有用硼氢化合物),燃烧室中最大燃气温度约在2000°K到2500°K范围之内,而且燃气的流速也相当大,其M数大约是0.5到1.0。在进行燃烧试验时,还要求测量出口截面上各点的局部温度,以判 A) Several problems in measuring the temperature of high-temperature and high-temperature gas Currently, jet engines generally use carbon-hydrogen compounds for fuel (some useful borohydrides as well). The maximum gas temperature in the combustion chamber is about 2000 ° K to 2500 ° K , And gas flow rate is also quite large, the M number is about 0.5 to 1.0. In the combustion test, it is also required to measure the exit section of the local temperature of each point to determine
