of Sciences, Shenyang 110016, China) Abstract: A theoretical model was established for the degassing of magnesium alloy by a spinning spray based on the analysis of the mass transformation of hydrogen... rotation speed from 230 r/min to 330 r/min. As a result, the diffusion content of hydrogen increases with rotation speed increasing, and the degassing efficiency increases. Verification experiment......

of PdCl2 and CuCl2, pH value, oxygen content, temperature, flow rate, PH3 concentration and catalyst amount on the purification efficiency of PH3 were explored. The results show that the optimal.../L, the purification efficiency of PH3 can reach 100% within 850 min. There are three oxidation-reduction reactions that can purify PH3 and regenerate the catalyst, and two complex reaction, which can......
