Decreasing the consumption of the advection pump, to decrease the pressure, to prolong the using time of the ion chromatographic column was discussed. 摘要通过适当降低往复平流泵的流量,来降低柱压,从而达到延长使用色谱柱的目的。
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. 结论在实验中简易的体位转流可起到稳定的转流作用,血流动力学变化与转流泵转流基本相同。
