摘要
利用WZR-1A型精密微电脑量热计测量8种红酒的恒容燃烧热。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红酒,装入已准确测定热值的燃烧杯中后,将测试数据用自编的计算机处理程序对测试数据处理,从而得到红酒的燃烧热值。此法准确、简便、实用,可用于日常检测工作。
The heat values under constant volume (Qv) of eight kinds of claret were measured by WZR-1A microcomputer calorimetry. After the benchmark substances were accurately quantified and then put into the oxygen bomb and filled in high pressure pure Oxygen, the sample was completely combusted in oxygen bomb and the time and the change of calorimeter temperature were recorded and then the data were analyzed by data treatment software to calculate apparatus heat capacity. Then a given amount of claret was filled in the combustion cup (the heat value of which was accurately measured), and the test data were processed by self-designed software to obtain the heat value of the claret. This method proved to be accurate, simple and convenient and could be used in routine analysis.
