海水与淡水中氰化物光化学降解的对比研究安路阳1,薛文平1,尤飞1,姜雪1(1.辽宁省大连市大连工业大学化工与材料学院)摘 要:氰化物的光化学降解是水中氰化物污染去除的重要途径之一,但在不同水体中氰化物的降解差异较大.文中对含氰海水与淡水进行了不同自然光照条件下的降解模拟试验.试验结果表明,光照越强,温度越高,氰化物降解越快;在相同试验条件下,氰化物在海水中的降解速率高于淡水.同时,还进行了紫外光照射条件下加入光催化剂TiO2的含氰海水降解试验,反应150min即可达到排放标准要求.对降解反应的动力学进行了分析,......
alloy[J]. Rare Metal Materials and Engineering, 2016, 45(8): 2116-2122. Degradation behavior of MgF2/HA composite coating on magnesium alloy in vitro ZHANG Chun-yan1, 2, ZHANG Shi-yu1, LIU Xin-peng1... of the micrograph and chemical composition of the MgF2/HA coating in Hank’s solutions were used to study the degradation process. The results indicate that, during the immersion in Hank’s solutions......
Residual life estimation based on bivariate Wiener degradation process with measurement errorsWANG Xiao-lin(王小林), GUO Bo(郭波), CHENG Zhi-jun(程志君), JIANG Ping(蒋平)(College of Information Systems...) was proposed, which was sharply different from existing work that only utilized one-dimensional degradation data. Once new degradation information was available, the residual life of the product being......
