摘　　要：基于人工肾透析过程的一维非稳态微Krogh模型,考察了人工肾透析过程中,三种血液循环模式下人工肾的传质情况,模拟了各种血液循环模式下可渗透溶质的清除率随时间的变化趋势以及透析时间随血液量的变化曲线,从而得出了一种最优的血液循环模式.本文模拟结果对临床提高人工肾的透析效率有重要意义.Based on the one-dimensional and unsteady-state Krogh model, this paper investigates mass transfer of artificial kidney with three blood cycle modes during the course of hemodialysis. The variations of the permeable solute clearance with increasing time and the dialysis time with increasing blood flux are simulated in detail,and then one optimal blood cycle mode is acquired. The results are very important to improve the clinical efficiency of artificial kidney.
