一、前言在工业生产和科学研究中,经常需要准确地测量高温气流的温度。采用热电偶直接和高温气流接触使之热交换达到平衡进行温度测量,由于测量方法十分简单,得到了广泛的应用。但是这种平衡法由于热电偶材料的限制,不能测量较高的气流温度,
I. Preface In industrial production and scientific research, it is often necessary to accurately measure the temperature of a hot gas stream. The use of thermocouple direct contact with high temperature air flow so that the heat exchange to balance the temperature measurement, the measurement method is very simple and has been widely used. However, this balance method due to the limitations of the thermocouple material, can not measure the higher temperature of the gas flow,
