摘　　要：在氧弹式量热器装置中，使用精密温差测量仪替代柏克曼温度计，并和ＰＣ系列微机实施联机测试。用Ｃ语言编制专用程序，实现定时间距采集温度数据同时在屏幕上动态显示升温曲线；实验操作结束，ＰＣ机在数分钟内完成数据处理与结果打印等工作。对比实验证明，联机方式明显地提高了测试精度。The Beckmann Thermometer is replaced by Model JDW-2C instrument of temperature difference in the apparatus of bomb calorimeter which was equipped with a microcomputer for on-line acquiring data and processing. When a special program of C language is used, the time-temperature data can be acquired and the dynamic curve can be displayed. After experimeantl operation was finished, the data processing and printout of results were made by the PC in a few minutes. The precision of determined results for the heats of combustion was apparently improved by this method.
