The determination of atmospheric phosphine in Ny-Ålesund

Phoshpine (PH3), a volatile and toxic gas, has been proved to commonly exist in the environment. The determination of gaseous phosphine and its emission fluxes in Ny-Ålesund is reported in this paper. Results showed that gaseous phosphine exist in Arctic atmosphere commonly and the concentration of phosphine ranged from 16.3–600.2 ng/m³, with the maximum concentration of phosphine in tundra areas and the minimum in surface air of ocean. The concentration of phosphine ranged from 65.79–1259 ng/m³ in colliery atmosphere at different altitudes and the maximum was found in the center of colliery. Emission fluxes of phosphine were different in various Arctic areas. Emission fluxes of phosphine from protected areas, with average concentration of 32.13±5.353 ng m^–2 h^–1, were higher than from other areas. And the flux of phosphine from ocean was lower.     

粒度组成对KR搅拌头用浇注料性能的影响

以Andreassen颗粒紧密堆积理论为基础,研究KR搅拌头外衬莫来石浇注料临界粒度和粒度组成对其密度、强度和热震稳定性的影响.结果表明,随着临界粒度的增大,浇注料干燥和烧结后冷态密度与强度均明显提高;临界粒度一定时,粒度组成对浇注料冷态密度、强度以及热震稳定性的影响基本一致,但临界粒度不同的浇注料试样达到最佳性能所对应的粒度组成并不完全相同;与冷态性能相比,浇注料热震稳定性受临界粒度的影响较小.

Research on catalysis of sodium-metallochlorophylls in Ni/MH battery

The effects of sodium-metallochlorophylls including sodium-iron chlorophyllin, sodium-copper chlorophyllin and sodium-magnesium chlorophyllin on performance of Ni/MH battery were investigated. The results show that sodium-iron chlorophyllin can effectively activate the gases produced during charge in Ni/MH battery, therefore reducing the reduction potential of oxygen and the oxidation potential of hydrogen, and the increased speed of inner pressure of battery is decreased significantly. With the aid of DMol3 software, the activation process of oxygen and hydrogen by sodiummetallochlorophylls was simulated and analyzed. It was found that the catalysis behavior is in agreement with the experimental results, and the activation process also gets a reasonable explanation from the calculated results.
