1) batch extraction
间隙萃取
2) extraction time
萃取时间
1.
Using selective extraction procedure,hydride generation atomic absorption spectrophotometry coupled with flow injection analysis system and corn pot experiment,five different extractants,including HCl,HOAc,EDTA,NH4OAc and MgCl2 were chosen,and the effects of extraction time,ratio of soil to solution on the extraction of bio-available Hg were investigated.
利用玉米盆栽实验,通过单一选择性萃取法和流动注射氢化物发生原子吸收光谱法测定,研究了HCl、HOAc、EDTA、NH4OAc、MgCl25种萃取剂在不同萃取时间、不同土液比下对土壤中有效态汞的萃取效果。
2.
Further discussion indicates desorption amount increases with the increase of microwave power and extraction time.
研究结果表明,微波场使目标成分获得可观的非热效应能是微波强化萃取解吸的本质原因,解吸量随微波功率或萃取时间的增加而增加,在位移极化相同或位移极化相对转向极化忽略不计条件下,微波场中极性物质比非极性物质获得更多的能量,微波对极性物质的萃取更有效。

补充资料：闭锁间隙
闭锁间隙----又叫弹低间隙。武器闭锁后，当枪机与机匣上的闭锁支撑面紧贴，枪弹以斜肩或底沿与枪管紧贴时，枪弹底面与枪机弹底窝平面之间的距离称为弹底间隙。若枪弹底平面与枪机弹底窝平面紧贴，则枪机匣上的闭锁支撑面之间的距离称为闭锁间隙。
