摘　　要：本文从理论上建立了近似的量热计热传导方程,推导出目前普遍采用的外推法理论依据,并对量热计温升曲线结果作了讨论和分析。用自制的自动测温仪表实现了盒式水量热计在加速器照射过程中温升的在线测量,进行了量热计热学特性实验。测量结果表明,热传导效应对量热计的影响是可以修正的。An approximate heat-conduction formula of the water calorimeter is theoretically estabilshed and the basis of the extrapolation method now in common use is deduced. By using a self-made automatic temperature measuring system, the on-line measurement of temperature rise of water in the calorimeter irradiated by an electron accelerator is realized. Experiments of heat characteristics of the water calorimeter are carried out, experimental results are discussed and analysed. The data leads to a conclusion that the effect of heat conduction to water calorimeter may be corrected.
