摘　　要：求出了患者～伴有超滤透析器系统两室模型的近似解，与解析解相比，该解形式简单、精度足够。用其拟合了８名患者的ｉｎｖｉｖｏ透析实验数据，对两室模型参数进行辨识，获得了满意的结果。pproximate solution of a two-compartment model for patient-dialy-zer system with ultrafiltration was deriVed. In comparison with the ana-lytical solution,the approximate one was much simple and accuratc enough.The approximate solution wgs used to simulate the in vivo hemodialysisexperimental data in & patients with satisfactory results.
