摘要
利用WZR-1A型精密微电脑量热计系统地测量了蜂蜜的恒容燃烧热。准确称取一定量的基准物质,放入氧弹中充入高压纯氧,将测试样品在氧弹中完全燃烧,并记录燃烧前后时间与量热计温度变化数据,运用仪器所带的数据处理软件计算出仪器热容量,然后再准确称取一定量的蜂蜜,装入已准确测定热值的燃烧胶囊中后,将测试数据用自编的计算机处理程序对测试数据处理,从而得到蜂蜜的燃烧热值。此法准确、简便、实用,可用于日常检测工作。
The heat value under constant volume （Qv） of honey were measured with WZR-1 A microcomputer calorimetry. After the benchmark substance were accurately quantified and the heat capable of the calorimetry was determined. The capsule with sample was put into the oxygen bomb, the sample was complete combusted in oxygen bomb with high pressure pure oxygen. These record of time and the change of calorimeter temperature were analyzed with the self-designed data treatment system of oxygen bomb combustion. This method was proved to be accurate, simple and convenient to be used in routine analysis.
