本文的目的是研究蛋白质牛血清白蛋白的介电行为。这项研究是为了解决其他工作人员在无线电波和微波频率范围内进行测量时出现的一些问题。为此，在尽可能宽的浓度、温度和pH范围内进行测量。证实了在200-2000 MHz频率范围内存在一个辅助色散，并讨论了这种色散的可能分子解释。可以得出结论，这种分散可能是由于水结合到蛋白质。通过假设一个介电混合物理论的结合水量与浓度和pH值的变化进行了估计。
The purpose of the work described in this paper was to investigate the dielectric behavior of the protein bovine serum albumin. The investigation was made to try and solve some of the problems that had arisen from measurements obtained by other workers in the radiowaveand microwave frequency range. To do this, measurements were made over as wide a concentration, temperature, and pH range as possible. It was con-firmed that there was a subsidiary dispersion in the frequency range 200-2000 MHz, and the possible molecular interpretation of thedispersion is discussed. It can be concluded that this dispersion is probably due to water bound to the protein. By assuming a dielectric mixture theory the variation of the amount of bound water with concentration and pH is estimated.
