[交流] 翻译求助

Ionic liquid 1-butyl-3-methylimidazolium chloride ([C4mim]Cl) was used as a dissolution medium and water as a extraction medium for extraction of Paeonol from dried root of Cynanchun paniculatum(Bye.)Kitag by microwave-assisted extraction. The conditions of MAE including the size of sample, solvent, ionic liquid/solid ratio, extraction power and time were optimized. Under appropriate MAE conditions, the extraction yield can reach high in a short time. The extraction yield by MAE was the same or even higher than conventional extraction methods. MAE only needs 8 min, but Soxhlet extraction extraction at room temperature, heat reflux extraction, ultrasonic extraction and need 24 h, 45 min, 75 min and 90 min, respectively. MAE was also available in pilot plant form for larger scale extraction.

大侠们，帮忙看一下有什么不妥之处

如果我儿子长大当军人，我会告诉他，做为军人，不仅要服从命令，还要服从真理和正义，生你的是父母，养你的是百姓，所以你所做的，必须对人民有利，永远记住，.

Ionic liquid 1-butyl-3-methylimidazolium chloride ([C4mim]Cl) was used as a (a在这里可以不要吧)dissolution medium and water as a(同上) extraction medium for extraction of Paeonol(改为extractinng Paeonol会不会好点,要不和后面的of有点重复) from dried root of Cynanchun paniculatum(Bye.)Kitag by microwave-assisted extraction. The conditions of MAE including the size of (different sizes of)sample, solvent, ionic liquid/solid ratio, extraction power and time were optimized.(头太大了,建议改为The conditions of MAE were optimized which included the different sizes of sample, solvent, ionic liquid/solid ratio, extraction power and time ) Under appropriate MAE conditions, the extraction yield can(时态一致could) reach high(少名词,加个level?) in a short time. The extraction yield by MAE was the same or even higher than conventional extraction methods. MAE only needs(needed) 8 min, but Soxhlet extraction extraction(多了一个?) at room temperature, heat reflux extraction, ultrasonic extraction and need(and 不要,needed) 24 h, 45 min, 75 min and 90 min, respectively. MAE was also available in pilot plant form for larger scale extraction.
不知道能不能帮上楼主
