摘　　要：提出了一种双热偶加热补偿式高温气流温度的测量方法,可以克服以往各种常用方法的弊端,有效地直接测出气流的温度,且测量的精度很高,为航空航天、能源动力及化学工程等领域提供了重要的测试手段。This paper gives a new compensative method of high gas temperature measurement. When the compensative conditions are satisfied, the real gas temperature is the indicated value of each thermal-couple. The method presented in this paper, compared with other general methods used before, has many advantages. It can overcome the deficiencies in other general methods used before. Through heating, the effect of radiant heat rejection can be effectively compensated for and the real temperature of high temperature flow gas can be measured directly, precisely and quickly. Its construction is often simple. Therefore it might be useful in aeronautical spaceflighl. chemical and power engineering research fields.
