(二)熔鋶与H_2反应对H_2压力的阶次H_2在铜中的溶解速率常数随铜中含硫量增大而减小,但当硫量增加达一定值后,速率常数不再减小。H_2在铜中的溶解度本来就不大,这可由下列公式计算求得:
(Ⅱ) The dissolution rate constant of H_2 pressure in H_2 reaction with H_2 reaction decreases with the increase of sulfur content in copper, but the rate constant no longer decreases when the sulfur content increases by a certain amount . H 2 solubility in copper is not large, which can be calculated by the following formula:
