Decreasing the consumption of the advection pump, to decrease the pressure, to prolong the using time of the ion chromatographic column was discussed. 摘要通過(guò)適當降低往復平流泵的流量，來(lái)降低柱壓，從而達到延長(cháng)使用色譜柱的目的。
Conclusion The postur venovenous bypass method could play a stable part in liver transplantation, its dynamic changes are similar with that of pump venovenous bypass method. 結論在實(shí)驗中簡(jiǎn)易的體位轉流可起到穩定的轉流作用，血流動(dòng)力學(xué)變化與轉流泵轉流基本相同。
