摘　　要：为了确认由等温式量热法测到过热的可信度和准确度,将热流式量热计引入氘/钯气-固系统。在不同实验条件下,分别讨论了输入功率(电流)和压力对过热的影响。实验结果表明,热流式量热法较等温式量热法具有更高的准确度。当氘气压力为3×104 Pa时,过热功率随输入功率的减少而变小,其中在输入功率为380 W时,得到热功率为(6.398±0.191)W;在讨论压力与过热关系的相关实验中,当氘气压力为220 Pa时,系统产生的过热功率为(10.284±3.402)W。实验中测得的过热远高于化学热,扫描电镜(SEM)及能谱(EDS)分析结果表明,此部分过热可能来自于某些核嬗变过程。A heat-flow calorimeter was introduced into the D/Pd gas-loading system to confirm the reliability and accuracy of the results obtained by isothermal calorimetry in the previous work.The effects of input power(electrical current)and pressure on excess heat were discussed under different experimental conditions.The results showed that the heat-flow calorimetry had higher accuracy than isothermal calorimetry.Under deuterium pressure of 3×104 Pa,the excess heat power decreased with the decrease of the input power,and the maximum excess heat power was(6.398±0.191)W with an input power of 380 W.In the experiments of discussing the relationship between pressure and excess heat,the results showed there was a maximum excess power of(10.284±3.402)W whenthe deuteriumpressure was 220 Pa.The excess heat measured in the system was far more than that in chemical reaction.The results of SEM and EDS implied that excess heat came from nuclear transmutation processes.
