摘　　要：为了解决放射性同位素核源的热功率测试需要,进行了同位素核源量热方法的研究,通过搭建热功率测试试验装置,对各种影响量热精度的因素进行了分项试验、计算分析。试验结果表明,基于Gardon型热流传感器原理的量热方法,对于基本测量对象,用厚度为1.0 mm的康铜片作为敏感部件,可以实现在120～130 W热功率范围内测试误差不大于1%,由试验研究分析表明测量原理可行,满足对同位素热源的量热精度要求。A testing method of radioisotope heat power was researched for the radioisotope heat source. A experiment equipment for thermal testing was assembled to calculate and analyze the effect factor of thermal testing precision. The results indicate that taking constantan sheet metal with thickness of 1.0 mm as the sensitive parts, the thermal testing technique based on Gardon type thermal flowage sensor, for the elementary measure objects, the testing error is less than 1% between 120 W and 130 W, and the experimental research indicate that the Gardon type thermal testing theory is feasible and satisfied with the precision need of radioisotope thermal testing.
