摘　　要：结合GB/T 213—2008要求和实例分析可知:在确定热量计热容量有效工作范围时,热容量值与温升若有明显的相关性即可根据其温升确定相应的热容量值;若连续5次热容量试验结果的相对标准差不超过0.20%,则其平均值可作热容量值,但不可视仪器的热容量为常数。According to the demand of GB/T 213—2008 and examples analysis,it is indicated that when determining effective working range of calorimeter,heat capacity may be determined based on temperature rise if there is correlation between heat capacity and temperature rise;and if relative standard deviation of five successive heat capacity results does not exceed 0.20%,its average may be considered as heat capacity value,yet heat capacity of instrument can not be regarded as constant.
