Experimental And Theoretical Research On Abnormal Phenomenon By Triggering In D(H)/Pd(Ni) Gas-Solid Systems

A new designed and built heat-flow calorimeter was introduced in the D/Pd gas-loading system and a series of experiments triggering by electrical current were made under some different pressure conditions. The calorimeter was calibrated in nitrogen atmosphere and the results between the input power?P? and the exothermal electromotive force?V? could be simulated by a quadratic equation: P =?15.356 ± 0.068? V –?0.014 ±0.039? V². When deuterium pressure(P_D2) was 3×10⁴Pa, excess energy of 0.70 ± 0.02 MJ was detected within 40 hours, which is corresponded to?1.6 ± 0.1? ×10³ eV for each palladium atom. If the loading ratio of deuterium was considered as 0.1, the magnitude order of excess heat would be four times higher than that in chemical reaction energy level to each deuterium atom. The input electrical power appeared a positive correlation trend to the excess heat, in which the maximum excess power of 6.398 ± 0.191 W was obtained when the input current was 8.47 A. In a related experiments for discussing the relationship between deuterium pressure and excess heat, the results showed a maximum excess power of 10.284 ± 3.402 W when P_D2 is 220 Pa. The total reproducibility of excess heat measurement was 10/10. In order to confirm the reliability and accuracy of the excess heat triggered by current in the previous work, a H/Pd gas-loading system had been calibrated accurately in the conditions of P=1atm N2, H2 and low vacuum?⁵Pa?, the results showed that the excess heat power was only about 0.6W when input power of 320 W. The experiments of H/Ni gas-loading system had been conducted in an isoperibolic calorimeter.According to the results of the speculation of calibration curve, if we chosen Ar to do the calibration experiment, the results showed that the excess heat power would be 25.478 W and 23.646 W when PH2 is 1×10⁴Pa, 3×10⁴Pa, and the input power was 318.89 W. If we chosen N2 to do the calibration experiment, the results showed that the excess heat power would be 19.268 W and 17.908 W when PH2 is 1×10⁴Pa, 3×10⁴Pa, and the input power was318.89 W. The experimental results show that the excess heat effect of calibration with Ar was obviously higher than that of N2. Because nearly all of triggering experiments in gas-soild systems were used currently Ar or N2 as a control in the Condensed Matter Nuclear Science, and the excess heat appeared in these experiments when the input power was more than 500 W. So we need to discuss in depth whether the excess heat has any correlation on these two calibration gases.
