| 摘 要： | 热电偶是工业温度测量常用的传感器,它具有精度高、经济和温度宽的特点。然而在测量过程中热电偶也会因为测量条件和环境限制而导致出现测量结果的不稳定性。例如:污染、氧化、还原、物理条件、脆裂、照射就是影响热电偶测量结果不稳定性的主要来源。

| Abstract: | Thermocouple is a common used sensor in industrial temperature t, which has characteristics of high accuracy, wide economy and temperature. However, during the measurement, the measurement results of thermocouple will have instability that caused by measurement conditions and environmental restrictions. For example： pollution, oxidation, reduction, physical condition, embrittlement, irradiation are the major sources. |
