A study on the structure of calcium nitrate tetrahydrate molten salt 四水硝酸钙熔盐的结构研究
Discussion on crease - resist finish technology of ca 2 to worsted cloth 硝酸钙对精纺毛织物进行抗皱整理的工艺探讨
Bio - remediation can be achieved in different ways , but in the case of the shing mun river , it involved injecting calcium nitrate into the sediment , thus converting anoxic pollutants into odourless gases such as nitrogen or carbon dioxide , and in the process removing offensive odours 生化处理可以多种形式进行,以城门河为例,处理程序是将硝酸钙注入沉积物内,使缺氧的污染物转化为氮或二氧化碳等无臭气体,从而消减臭味。
