随溶质初始浓度的增大，有机相的溶质浓度向饱和萃取量接近；
The acid concentration in organic phase increased and approached the stoichiometric saturating value with the increase of the acid concentration in aqueous phase.
研究了样品萃取量、超声波萃取时间、以及不同萃取溶剂对微量挥发性成分萃取效果的影响。
The effects of sample concentration, ultrasonic extraction time, and different extracting solvent on the extraction of volatile microconstituents were also investigated.
我喝过一些非常棒的espresso是Paul Bassett用这种手法做出来的，但是我个人还是喜欢比较淡一点的，萃取量多一点的方式来呈现我自己的配方。
I have had some great shots made by Paul Bassett where he used this method, but I personally prefer a lighter texture and a longer shot when I use my own blend.
