| 摘 要： | 采用精密的量热仪测定含虹原油的比热容也会产生较大的偏差，基信要原因在于测试过程中量热容器内存在着两个相变过程，邓气液之间的相变液相析出石蜡结晶的相变，以及随着温度下降试样内传热性能变坏。

| Abstract: | There is a relatively big error in measuring specific heat of waxy crude oil by accuracy calorimeter, the prime cause is two of phase change in process of measurement in calorimeter, i. e. phase change between gas and liquid, and due to wax crystallized out of liquid phase, heat transfer of samples getting worse with the temperature dropping, structure of fin -tube in calorimeter can affect on accuracy of heat metering, the size of gas space in calorimeter on correctness. The paper presents analysis method of optimizing fin -tube number, and discussion of optimal gas space in calorimeter. |
