随着喷气技术及火箭技术的发展,气流温度测量愈来愈显得重要.采用能以所需准确度直接给出总温的总温热电偶是测量气流温度的有效途径.凭借经验设计的总温热电偶往往难以保证所需的准确度.Haig提出的方法虽然有可能获得所需的准确度,但在分配热电偶误差时仍需凭借经验,很难保证热电偶处于最佳状态.本文介绍的一种按最佳
With the development of jet technology and rocket technology, it is more and more important to measure the airflow temperature.Using the total thermocouple, which gives the total temperature directly with the required accuracy, is an effective way to measure the airflow temperature.According to the total design experience Thermocouples often find it difficult to guarantee the accuracy required, although the method proposed by Haig, though it is possible to obtain the required accuracy, still has to rely on experience in assigning thermocouple errors, making it difficult to keep thermocouples in the best condition. Introduced by a kind of the best
