摘　　要：提出了在低温试验条件下较精确的温差测量方法，并举例说明了用温差热电偶测量温差的方法较传统测试方法的精确程度。The paper gives the accurate method for measuring temperature difference of thermocouples at low temperature and its error analysis, and states with an example that the way of using the temperature difference thermocouples to measure temperature differnce is more accurate than that of using traditional methods. Therefore, it is especially suitable for measuring the little temperature differnce in the heat transfer experimant.
