Changshagou adakite, an outcrop in the middle segment of the South Altyn Tagh ultra-high pressure metamorphism(UHPM) terrane, contains medium-K cal-alkaline and weakly peraluminous compositions(Si O2 = 66.79% to 68.65%, Al2O3 = 17.48% to 18.31%, K2 O + Na2 O = 6.32% to 6.88%, K...
通过配合法合成了铌酸盐K4Nb6O17,采用X-射线衍射,扫描电镜等对K4Nb6O17进行了结构和形貌表征.在I-为电子给体,RuO2为助催化剂的情况下,研究RuO3-K4Nb6O17在波长约为360 nm紫外辐射下分解水的产氢活性,讨论了制备温度和I-离子浓度对K4Nb6O17光催化分解水产氢活性的影响,且对配合法与高温固相法制得的K...
钝化剂对自行研制的火电厂锅炉酸洗用的H2O2—LP—1新型复合型钝化剂,从电化学的角度探讨了可行性.结果表明,复合型钝化剂的钝化效果可与NaNO2相媲美,而且可实现钝化液的无污染排放,这与作者所做的工业试验及实验室挂片试验的结果完全一致.杨昌柱华中科技大学环境科学与工程学院濮文虹...
晶体结构在晶体[Yb(H2O)(acac)2(Ac)]2的结构研究中,应用了晶胞空间和倒易空间等效点的矩阵表示与系统消光规律的统一代数公式,确定了其空间群为Pbcn,并用空间群Pbcn验证了系统消光规律的统一代数公式.申成长沙电力学院化学系钟敦南长沙水电师院学报:自然科学版...
