The minimum liquid& vapor ratio and the Height of Mass Transfer Unit "HTU" can be obtained in lack of interphase heat transfer coefficient by the model.

Meanwhile, a correlation of HTU of mesh plate column with the factors such as rotating speed, flow rate, viscosity and holding-up rate is obtained.

并获得网格塔传质单元高度与转速、流率、粘度及滞存率等各因素的关联式。

The correlations of the packing factor of pressure drop, packing factor of flooding point, and HTU of the true liquid phase mass transfer were obtained.

获得了压强降填料因子、泛点填料因子，以及液相真实传质单元高度的关联式。

Objective: Study the reports on the hepatotoxicity ( HTX) of herbs in certain literature and the relation between the HTX and four characters ( FC), five tastes ( FT), channel distributions ( CD) and active components ( AC) of herbs.

目的：研究有关文献资料中中药肝毒性的报告及其与四气、五味、归经、有效成分之间的关系。

Background Heart transplantations ( HTx) have become the effective therapy to sorts of terminal cardiopathy with progress of heart preservation, surgical technique, immunosuppressive and antiseptic drugs.

研究背景随着免疫抑制剂的应用，心脏保存以及心脏外科技术的进步和高效抗感染药物的应用，心脏移植已成为治疗各种终末期心脏疾病的最有效的手段。

Therefore, HTx transplantation ( Hepatocyte transplantation, HTx) that has the advantage of mini invasive and fewer complications has important clinical significance.

因此，开展具有侵入性小，并发症少等特点的肝脏细胞移植（hepatocyte transplantation，HTx）具有重要临床意义。

It can solve the main problems of the HTx, the lack of human liver cells and serious immunological rejection after transplantation, at the same time.

从而可以同时解决移植细胞来源匮乏和移植后免疫排斥这两个肝细胞移植面临的主要问题。

Conclusions: There exists some relation between herbs property and HTX. To study and analyze the harm of herbs with literature statistics method is feasible.

结论：中药药性理论及有效成分均与肝毒性有一定的关系，应用归类分析的方法对文献资料进行分析研究是中药毒性研究中确实可行的方法。

The HGF concentration of rats serum and liver tissue of each group heightened and become obviously on 3d after HTx.

各组HTx后血清和肝组织HGF浓度均有升高，3d时增高最为明显。

Methods: Applying literature statistic method, add up, classify and analyze 55 herbs with HTX.

方法：应用文献研究方法，对55种具有肝毒性的中药进行统计归类分析研究。
