| 摘 要： | 科研和生产中需要在小空间条件下进行高温透明气流的温度测量,现有的高温测量方法不能很好地满足其要求。这里提出对三热电偶组合式高温测量加以扩展的方法——四热电偶法。此法避开了须先求测量环境常数的困难,克服了求解方程可能存在的发散问题,使即时显示和输出测量结果成为可能。

| Abstract: | There is the need for measuring temperature of gas flow at high temperature within narrow spaces for purposes of scientific research and production, while current methods can not meet the need satisfactorily. A new method, 4 - thermocouple method for high temperature measurement is given in the paper, developed from the principle of 3 - thermocouple method. The new method makes it possible to display and transmit temperature readings instantly, avoiding the troubles determining the environmental factor in advance and diverging of equation solutions from each other. |
