Equivalence zone in the precipitation test was characterized by the fact that the number of the antigen determinants was equal to the number of active antibodies centres, irrespective of the heterogeneity of the latter. This permits to assess the antibody concentration in the values of the antigen valency. The new method of determination of the antibody heterogeneity index is based on recording the titre of the antigen and antibodies in the equivalence zone.
沉淀试验中的等价带的特征在于，抗原决定簇的数量等于活性抗体中心的数量，而与后者的异质性无关。这使得可以根据抗原价的值来评估抗体浓度。抗体异质性指数的新测定方法基于对等值带中抗原和抗体效价的记录。
