nh4hco3 meaning in Chinese
碳酸氢氨
Examples
- With the proportion does not change at present ( namely ca ( h2po4 ) 2 = 2 : 1 ) , the application rate of each mu slope cultivated land should be rised to 100 kg nh4hco3 + 200 kg ca ( h2po4 ) 2
在目前施肥比例不变的前提下(即碳铵：过磷酸钙= 2 ： 1 ) ，每亩坡耕地施肥量应从50kg碳铵+ 100kg过磷酸钙增加到每亩100kg碳铵+ 200kg过磷酸钙。 - 3 . when apply fertilizer quantity is 1 . 5 to 2 times to the present quantity on bench terrace , wheat output raise obviously . but the best application rate is 1 . 5 times to the present quantity ( namely 75 kg nh4hco3 + 150 kg ca ( h2po4 ) 2 per mu )
在黄?土地区水平梯田上，施肥量达到目前施肥量的1 . 5到2倍时，小麦产量明显提高，但以施肥量为目前1 . 5倍(即每亩施75kg碳铵+ 150kg过磷酸钙)时为最佳。 - Yttrium aluminum garnet ( y3al5o12 , yag ) is not only a very important laser material , but also a high - temperature structural material and a fluorescence material . in this paper , the discussions are mainly focused on the synthesis of yag powders by co - precipitation method , self - propagating high - temperature synthesis and mixed method , powder ' s property , etc . in the co - precipitation method , the precursor was produced by adding a mixed a1 ( no3 ) 3 and y ( no3 ) 3 solution to nh4hco3 solution . yag can be obtained by heating the precursor at looo ' c for 5 hours without the formation of yam and yap transition phase
钇铝石榴石( y _ 3al _ 5o _ 12 ，简称yag )是一种重要的激光基质材料，同时它还作为高温材料和荧光材料得到了广泛的应用，本文主要讨论了化学共沉法、燃烧法制备yag的超微粉的工艺，并对yag超微粉的性能及物相进行了分析；采用固相合成法制备了ca ， ca ： yag系列陶瓷，并对其结构和性能进行了讨论。 - Moreover , the quenching concentration of eu is raised . on the basement of successful synthesis of two - components oxide , edta complexing sol - gel method was expanded and applied to effectively synthesis nanosized muti - components oxide , such as la1 - xsrx fe o3 , lafe1 - xcuxo3 , la1 - xsrx coo3 , laco1 - xcuxo3 because edta can bind with most metallic elements of the periodic table , this technique become a versatile tool in the production and study of new nano materials of multi - component complex oxides . a economic and new process has been studied to synthesis la2o3 nanocrystalline , using nh4hco3 as precipitant
河北大学理学博士学位论文对于单一组份的稀土氧化物，探索出一条更经济、更方便的合成方法，即:用碳酸氢钱做稀土沉淀剂，成功地制备了纳米l匆03 ，并对中间产物碳酸斓及其烧成的氧化斓分别进行了ir 、 tg一dta 、 sem 、 xrd分析研究，确定了碳酸悯的组成，氧化斓的物相、结构，并发现分散剂的种类对微观形貌有一定的影响。
