| Abstract: | The model of multicenter extraction was brought forward on the base of Fick law.A mapping model of extraction time and concentration were set up according to the experiment.The extraction mechanism by the high intensity pulsed electric fields(HPEF) was discussed.The advantage of short extraction by the HPEF was explained in the abstract though the mathematics and geometry model of extraction.An effective theoretics analysis tool was supplied to extraction of solid and liquid matter though this model. |
