本文选用具有不同原始状态的钯棒作为阴极,在自制的循环水冷却式量热计中进行了7次长时间电解重水的量热实验观察,实验过程中仅观察到一次异常温升现象。在理论分析和实验的基础上,排除了化学反应和D-D聚变产生异常温升的可能性,并认为过剩热的产生是由于钯晶体内弹性应变能的释放所引起。
In this paper, palladium rods with different initial states were selected as the cathode. Seven experiments of long-term Electrolyzed heavy water were carried out in a self-made circulating water-cooled calorimeter. Only one abnormal temperature rise was observed during the experiment. On the basis of theoretical analysis and experiment, the possibility of abnormal temperature rise caused by chemical reaction and D-D fusion is ruled out. It is considered that the excess heat is caused by the release of elastic strain energy in palladium crystal.
