摘　　要：采用同一标定过程,同时采集符合GB/T213—2003和GB384—1981中标定恒温氧弹热量计热容量所需的数据,然后采用各自陈述的方法计算。在不同室温下得到的热容量值,除有不具随机特性的负偏差外,还随室温变化;尤其温差较大时,差值具有显著性。认为用热量计测定物质热值时,要用同一方法测量和计算,且环境温度应尽可能接近。Required dates for standardization of thermal capacity of thermostatic oxygen bomb calorimeter were collected at the same time according with GB/T 213-2003 and GB 384-1981 in the same standardization process, and then the data were calculated respectively by their own ways. Besides possessing non-random negative deviation, the thermal capacities obtained at the different room temperatures change with the room temperature. The bias is remarkable when the temperature difference is large especially. It is considered that the same method to measure and calculate the heat value should be adopted in measuring heat value of material by calorimeter and the environment temperatures should be as close to each other as possible.
