Fricke's assumption, that the dielectric constant of the erythrocyte wall is 3, is discussed. The assumption is approximately correct in the case of a solid layer of any thickness, and in the case of a liquid layer of not more than bimolecular thickness. For liquid layers of greater thickness the dielectric constant may be several times greater than 3. Calculated values based on experimental determinations are given of the dielectric constants of the polar groups of unimolecular films.
弗里克的假设,即红细胞壁的介电常数为 3,对此进行了讨论。对于任何厚度的固体层,以及不超过双分子厚度的液体层,这种假设是近似正确的。对于较厚的液体层,介电常数可能是 3 的几倍以上。根据实验测定,给出了单分子膜的极性基团的介电常数的计算值。
