摘要
用精密自动绝热量热计测定了中原、胜利原油以及二者以１５、１６、１７质量比配制成的混合原油在１０—７０℃温度区间的比热容。并以５℃间隔给出了分度值，列出了详细的数据表。以纯水作为标准物质，在其液相区间进行了比热容测定，确证装置的测试精密度为±０．２％，准确度在±０．
Heat capacities of two kinds of crude oils from Zhongyuan and Shengli Oil Fields and three kinds of mixed oil,prepared by the above two kinds of oil in the ratio of 1∶5,1∶6 and 1∶7,were measured with a precision automatic adiabatic calorimeter in the range 10 70℃.All experimental results are smoothed and tabled at an interval of 5℃. The reliability of the calorimeter was verified by the mesurement on the standard reference material,pure water.The precision and accuracy of the measurements are ±0 2% and ±0 3%,respectively,in the whole experimental temperature range.
