1Electrochemistry of samarium in lithium-beryllium fluoride salt mixture显示文摘The electrochemical behaviour of samarium was investigated in LiF-BeF2 system on an inert (Mo) electrode by cyclic voltammetry and chronopotentiometry at 804, 833, 847 and 872 K. Redox process Sm3++e-→Sm2+ was recognized and analysed. Cyclic voltammetry data suggested that at potential sweep rates lower than 0.25 V/s, the reduction was limited by the diffusion of Sm3+ ions. It was not possible to observe reduction process of Sm2++2e-→Sm0 due to insufficient electrochemical stability of LiF-BeF2. Diffusion coefficients of Sm3+ ions in LiF-BeF2 were calculated from voltammetric and chronopotentiometric data in the temperature range 804-872 K. Diffusion coefficient values obeyed Arrhenius law. Activation energy was calculated to be 102.5 kJ/mol.Martin Straka Michal Korenko Frantisek Lisy Lórant Szatmáry 2011Journal of Rare Earths2011,29,8:3
2封冻期高纬度湖泊底层溶解氧浓度的变化特征分析显示文摘溶解氧是评价水质好坏的重要参数,对水中生物的生存状况影响很大,而封冻后的湖泊,水中溶解氧的变化更加值得关注.对于高纬度地区的湖泊冬季封冻时间比较长,光照时间比较短,湖泊中的溶解氧与水温相对封冻前变化比较大.通过对2013—2014冬季芬兰Valkea-Kotinen湖封冻期底层水中的溶解氧浓度与水温数据的研究,讨论了在整个封冻期该湖3-6m深度溶解氧浓度的时空变化情况,其随着封冻时间持续下降,在融化前有比较大的跃升.得到了不同深度的溶解氧浓度与水温变化的回归方程,在最底层溶解氧浓度与水温的拟合优度最差,因此在最底层影响溶解氧浓度的变化因素更为复杂一些,不仅仅受水温变化的影响.通过对溶解氧的功率谱分析,可见在3m深度的周期是24h,但是4-6m深度日变化周期并不明显.通过对底部无氧层的分析,发现在封冻后的第36天,底部6m深度的溶解氧耗尽,得到了底部无氧层厚度随冰封持续时间变化的对数表达式.柏钦玺 李志军 冯恩民 李国玉 Lauri Arvola Matti Lepprant 2018数学的实践与认识2018,48,1:2
