硝酸铈 meaning in Chinese
cerium nitrate
cerous nitrate
Examples
- Effect of ce 3 on seed germination of chinese cabbage under acid rain stress
硝酸铈对酸雨胁迫下白菜种子萌发的影响 - Nanocrystalline ceo2 powders were prepared by sol - gel method using citric acid as complexation
以硝酸铈和柠檬酸为原料，采用溶胶-凝胶法制备了ceo _ 2纳米晶。 - From the experiment , the optimum preparation condition is as follows : ce3 ~ vcitric = 1 : 3 , reaction temperature is 65 ? , ph is 2 - 3 , drying temperature of gel is 80 ? , sintering temperature is 500 ? and sintering time is 2h . crystal grows up in two steps
通过实验得出最佳实验条件，硝酸铈与柠檬酸的摩尔比为1 ： 3 ，在65水浴中反应成胶， 100下烘干， 500焙烧，可得到平均晶粒尺寸为7nm的ceo _ 2纳米晶。 - Secondly , the grafted membranes were prepared by grafting 2 - acrylamido - 2 - methyl propane sulfonic acid ( amps ) on pretreated membranes using cetric ammonium nitrate ( can ) as an initiator in the aqueous medium . the surface compositions of the grafted membranes were determined by fourier transform adsorption spectrum ( ftir ) and x - ray photoelectron spectroscopy ( xps ) . and the morphology of the grafted membranes was studied by scanning electron microscopy ( sem ) and atomic force microscopy ( afm )
然后，选用硝酸铈铵作为引发剂， 2 -丙烯酰胺- 2 -甲基丙磺酸( amps )为接枝单体，在水溶液体系中进行接枝共聚反应制备pvdf ? g ? amps中空纤维膜，并利用傅立叶红外光谱( ftir ) 、 x光电子能谱( xps ) 、扫描电子显微镜( sem )及原子力显微镜( afm )等检测手段证实了接枝共聚物的存在。 - It is significant for reducing the product cost and improving the comprehensive property of the superabsorbent composite . using ammonium eerie nitrate and n , n ' - methylene - bis - acrylamide as an initiator and crosslink agent respectively , a superabsorbent composite is prepared by graft polymerization of acrylamide on starch at the presence of clay suspension , followed by hydrolyzing , washing , drying , grounding and filtering
本文以硝酸铈铵为引发剂， n ， n -亚甲基双丙烯酰胺为交联剂，使淀粉、粘土接枝共聚丙烯酰胺，经过水解，洗涤，干燥，粉碎制得粘土-淀粉接枝共聚丙烯酰胺的超吸水性复合材料。
