本文介绍了在80～400K 精密自动绝热量热计的基础上引入微机,用于量热试验全过程自动控制的方法。包括温度、电能的自动测试、数据处理及结果打印,也可进行人机对话,选择实验条件和参数调整。经过二年实验考察表明,装置性能稳定可靠,α-Al_2O_3的标定结果表明,其测试精度为±0.34%,准确度为±0.9%。 This paper introduces the introduction of microcomputer in the 80 ~ 400K precision automatic adiabatic calorimeter for the automatic control of the whole process of calorimetry. Including temperature, power automatic test, data processing and result printing, but also for human-computer dialogue, select the experimental conditions and parameters adjustment. After two years of experimental study showed that the device performance is stable and reliable, α-Al_2O_3 calibration results show that the test accuracy of ± 0.34%, accuracy of ± 0.9%.
