In chapter four, we study the second isoperimetric connectivity of line graphs and line digraphs. For line digraphs, we show that the second isoperimetric connectivity of strongly connected line digraphs with δ≥ 2 equals its connectivity. For line graphs, we give a sufficient and necessary condition for the existence of the second isoperimetric connectivity, and we show that under the condition that the second isoperimetric connectivity exists, the second isoperimetric con

第四章研究线图和有向线图的第二等周点连通度，得到了如下结果：(1)最小度大于等于2的强连通有向线图的第二等周点连通度等于它的点连通度；(2)对于无向线图，我们给出了第二等周点连通度存在的充要条件；(3)对于第二等周点连通度存在的无向线图，它的第二等周点连通度或者等于限制点连通度或者等于最小度和次最小度的和。

And adsorption of jack bean proteins onto the amphoteric resin was studied in this paper. The amphoteric resin was in innersalt form. The results of adsorption experiments show that when the proteins are adsorpted into the amphoteric resin in the neutral phosphate buffer solution, the diffusion coefficient of protein is near twofold in 0.4 mol/L NaCl phosphate buffer solution than that in solution without salt, and the adsorption capacity of protein also rises at the same ti...

通过盐浓度对吸附的动力学和热力学影响的研究，结果表明，在中性磷酸盐缓冲液中，两性树脂吸附刀豆蛋白，有盐( 0 。4mol/L Na Cl)的比无盐的扩散系数提高将近一半，且吸附量增加，其吸附等温线的效率在最初始部分高于无 Na Cl时的；随着盐浓度( 0～ 1 mol/L Na Cl)的提高，树脂对蛋白的吸附量也变大，盐浓度提高时树脂膨胀体积的增大与蛋白吸附量的增加呈线性关系，内盐型两性树脂对大分子蛋白质的吸附作用与小分子高价离子的相似，同样是通过内盐键破裂吸附。
