- 摘要:
- 利用 WZR-1A 型精密微电脑量热计系统地测量了食用大豆油的恒容燃烧热。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食用大豆油, 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, 从而得到食用大豆油的燃烧热值。此法准确 、简便、实用,可用于日常检测工作 。
- Abstract:
- T he heat values under constant volume (Qv)of edible soya oil were measured with WZR-1Amicrocomputer calorimetry .After the benchmark substance were accurately quantified and the heat capableof the calorimetry was determined.The capsule with sample was put into the oxygen bomb, the sample wascompletely combusted in oxygen bomb with high pressure pure oxygen.These record of time and thechangely of calorimeter temperature were analyzed with the self -designed data treatment system of oxy-gen bomb combustion.This method was proved to be accurate , simple and convenient to be used in routineanalysis.
