[求助] 求一篇实验注意事项的翻译

翻译下文:
“这一过程需要注意以下事项:
1、第一次将支链淀粉-三(苯基氨基甲酸酯)的四氢呋喃溶液加入氨丙基硅胶中要呈稀粥状,磁搅拌子刚好能够自由转动,一次加入过多会导致涂敷不均匀,待溶剂挥发磁搅拌子不能匀速搅拌后,再次加入支链淀粉-三(苯基氨基甲酸酯)的四氢呋喃溶液使氨基硅胶呈稀粥状。这样连续几次,直到溶液加完。
2、溶液加完后,待溶剂挥发致使磁搅拌子不能搅拌时,用药勺进行手工挤压(动作要快,连续挤压,否则结块),直到溶剂完全挥发干,涂敷好的固定相呈原始硅胶的均匀细滑感,如果颗粒大小不一或有沙粒感要进行重新涂敷。
3、重新涂敷首先用异丙醇进行悬浮,将上浮的细小颗粒(合格)转移至另一烧杯中,剩下的颗粒物进行适当的加热(不可过热,保持搅拌),目的是挥发所含的异丙醇溶剂,待到溶剂没有完全挥发,还有一定的潮湿感,加入少量四氢呋喃,呈现粘稠状便可,再进行人工挤压,直到固定相颗粒都分散开。加入异丙醇重新悬浮,将合格品吸出,转移合并到烧杯中。”

支链淀粉-三(苯基氨基甲酸酯) 直接用 ATPC表示

This process needs to note the following:
   1, the first time amylopectin - (phenyl carbamate) THF solution was added to the aminopropyl silica gruel-like, magnetic stir just enough to free rotation, the first by adding too much can cause the coating uneven a magnetic stir bar to be solvent evaporation is not uniform mixing, again by adding a THF solution of branched-chain starch - (phenyl carbamate) was gruel-like amino silicone. This successive solution until end of the increase.
   2. Solution and after until the solvent evaporation resulting magnetic stir bar can not be stirred, medication spoon hand-squeeze (action, continuous extrusion, or agglomeration), the stationary phase until the solvent completely evaporate dry coating good was uniform and smooth sense of the original silica gel, particle sizes or sand a sense to be re-coated.
   3, re-coating First with isopropanol suspension, floating small particles (qualified) to be transferred to another beaker, and the remaining particulate matter to the appropriate heating (not overheating, keep stirring), the volatile contained isopropanol solvent until the solvent not completely volatile, there is still some moisture sense, adding a small amount of THF, showing thick can then manually squeeze, until the stationary phase particles dispersed. Isopropanol to re-suspension, qualified product suction, transfer the merged into the beaker. "
Amylopectin - (phenyl carbamate) using ATPC
楼主你再看看,不行我在帮你修改.
天道酬勤!
