Second, because the thoracic duct drainage can be particularly lymphocytes from the large number of T cells in vitro, to reduce its dermal layer deposition, as well as the release of lymphokines, resulting in T-cell subsets change, helper T cells and the inhibition of T-cells ratio decreased the humoral immune function, B cells to produce specific antibodies decreased.

二是因为胸导管引流术可以把淋巴细胞尤其是T细胞大量排出体外，减少其在真皮层内的沉积，以及淋巴因子的释放，从而导致T细胞亚群的改变，辅助性T细胞与抑制性T细胞比值下降，体液免疫功能改变，B细胞产生特异性抗体能力下降。

The flow field in the axisymmetric crenellated radial labyrinth seal is simulated by the present numerical scheme, which emphsizes on examining the influence of relative teeth engaging length τ/T on the sealing property. It is found that the sealing property is firstly improved with the increase of engaging length, and becomes worse as the τ/T further increase, thus an optimal τ/T is existed.
