本文从简化Ouano扩散方程出发,选用非均匀圆柱形孔模型和合适的D_s(M)、D_m(M)关系,模拟Ouano、Smit和Tung的数据,得到较好的结果,应用Gram-Charlier级数形式的解析解讨论了V_e(Q)关系,解释了Haller和Yau的实验并评价了后者的KGPC公式,从理论上指出如若单分散标样的V_e符合Benoit普适标定,那么由于峰加宽效应引起的σ_B~2、α_(3B)、α_(4B)和G(v-y)也是可以普适标定的,解释了Tung关于σ_B~2不依赖于试样化学组成的发现,讨论了σ_B~2、α_(3B)、α_(4B)(K_e)对粒子大小、孔径分布、流速和装柱效率的依赖性,应用物料平衡方程的理论解释了Limpert关于细粒子凝胶柱效在某一流速下出现极大值的实验,并指出不应理解为对于高分子试样在该流速下也会有最好的分离,提出了根据色谱柱总柱效估计(?)_n(t)/(?)_n(∞)或(?)_w(t)/(?)_n(∞)的近似公式。
Based on simplifying the Ouano diffusion equation, this paper chooses the non-uniform cylindrical pore model and the suitable D_s (M) and Dm (M) relationships to simulate the data of Ouano, Smit and Tung, and obtains good results. The Gram-Charlier series The form of analytic solution discusses the relationship of V_e (Q), explains the experiment of Haller and Yau and evaluates the KGPC formula of the latter. It is theoretically pointed out that if V_e of monodisperse standard accords with Benoit universal calibration, The effects of σ_B ~ 2, α 3B, α 4B and G vy can also be universally calibrated. The results of Tung’s finding that σ_B ~ 2 does not depend on the chemical composition of the sample are explained, and σ_B ~ 2 , Α_ (3B), α_ (4B) (K_e) on particle size, pore size distribution, flow rate and packing efficiency, the theory of material balance equation is used to explain the effect of Limpert on the effect of fine particle gel at a certain flow rate Maximum value experiment, and pointed out that it should not be understood that the polymer sample will have the best separation at this flow rate. A new method is proposed based on the estimated total column efficiency (?) _n (t) / (?) _n (∞) or (?) _ W (t) / (?) _ N (∞).
