1.血液阻力和容量随频率增加的实验值(R(ω))、(C(ω))的变化可用以下公式近似表示：方程式中Ro和Co为血液在低频时的阻力和容量，见PDF为方程式中血液在无限频率时的阻力。公式(1)和(2)是通过将血液等同于图1.2的图(A)中所示的系统来推导的。通过将公式(1)应用于我们的实验数据，可以高精度地外推R(∞)的值。R(∞)表示阻力)，如果小体周围的膜可以被去除，那么在低频率下就会获得阻力。3.利用R(∞)的实验值、血液的体积浓度和血清的比阻，可用公式(5)计算出红细胞内部的比阻。4.小牛红细胞内部的比阻为血清比阻的3.5±10倍。
1. The variation of the experimental values (R (ω)), (C (ω)) of the resistance and capacity of blood for increasing frequencies is approximately represented by the equation: See PDF for Equation in which R o and C o are the resistance and capacity of the blood at low frequency and See PDF for Equation is the resistance of the blood at infinite frequency. Formulæ (1) and (2) are derived by considering the blood as equivalent to the system shown in the diagram (a) of Fig. 1. 2. By the application of formula (1) to our experimental data the value of R(∞) can be extrapolated with high accuracy. R(∞) represents the resistance) which would have been obtained at low frequency, if the membranes around the corpuscles could have been removed. 3. The specific resistance of the corpuscle interior can be calculated by equation (5), using experimental values for R(∞), for the volume concentration of the blood and for the specific resistance of the serum. 4. The specific resistance of the interior of the red corpuscle of the calf is found to be 3.5 ± 10 per cent times the specific resistance of the serum.
