ＳｒＴｉＯ４电容基本上不受磁场影响，但是它的灵敏度和使用温区有限，更大的缺点是测量时必须等半个多小时才能稳定，给实验带来不便．渗碳玻璃电阻温度计（ＣＧＲＴ）受磁场的影响比较小，其磁阻值可以精确计算．本文介绍了用在磁场中测量到的ＣＧＲＴ的电阻值，计算出磁阻造成温度误差，从而得到温度的精确值．为了使用方便，本文给出了磁阻造成温度误差的修正表，从而较方便地基本上消除了磁场造成的误差．在温度为４．２－８８Ｋ，磁场为０－１９Ｔ时，磁场造成误差小于０．ｌ％；在８８－３０６Ｋ，０－１９Ｔ时，误差小于０．２％．本文还介绍了用ＣＧＲＴ在强磁场中精确控温的方法．
SrTiO4 capacitance is basically not affected by the magnetic field, but its sensitivity and the use of temperature is limited, the greater disadvantage is that the measurement must wait for more than half an hour to be stable, to the inconvenience of the experiment. Carburized glass resistance thermometer (CGRT) by the magnetic field is relatively small, the magnetoresistive value can be accurately calculated. This article describes the resistance of a CGRT measured in a magnetic field and calculates the temperature error caused by the reluctance to find the exact temperature. For ease of use, this paper gives a correction table of the temperature error caused by magnetoresistive, so that the error caused by the magnetic field can be basically eliminated easily. At a temperature of 4.2-88K, a magnetic field of 0-19T, the magnetic field caused by less than 0 error. l%; at 88-306K, 0-19T, the error is less than 0.2%. This article also describes how to use CGRT to precisely control temperature in a strong magnetic field.
