摘　　要：通过对机械式表面温度计校准平台的材料、高度进行比较试验,结果表明采用由镍磷合金加工且平台高度至少100mm的校准平台在中心位置实际温度和平台表面的温度均匀性、波动性两方面的试验结果均优于其他两种材料,在试验过程中达到稳定条件的所需时间较短,更有利于开展机械式表面温度计的日常校准工作。By comparing the material and height of the mechanical surface thermometer calibration platform,The results show that the calibration platform made of nickel-phosphorus alloy and the height of the platform should be at least 100mm is superior to the other two materials in terms of the actual temperature at the center position and the temperature uniformity and fluctuation of the platform surface.The time required to achieve stable conditions during the test is shorter,which is more conducive to the daily calibration of mechanical surface thermometer.
