给出了掺氢冰介电测量的实验结果。在比本征德拜色散更低的频率侧观察到介电低频色散，并根据弛豫时间和介电强度对温度的依赖关系进行了讨论。在交直流电导率随温度变化出现交叉现象的掺氢冰中，低频色散的弛豫时间在交叉温度以上是恒定的。在交叉温度以下，随温度的降低而增大，但在温度依赖性上，掺氢冰的德拜弛豫时间与低频色散之间没有明显的交叉。
Experimental results for the dielectric measurement of HCl-doped ice are presented. A dielectric low-frequency dispersion was observed at a lower frequency side than the intrinsic Debye dispersion and is discussed on the basis of the temperature dependence of the relaxation time and the dielectric strength. In HCl-doped ice showing crossover phenomena between ac and dc conductivities on temperature dependence, the relaxation time of the low-frequency dispersion is constant above the crossover temperature. It increases with decreasing temperature below the crossover temperature, but HCl-doped ice does not clearly show crossover between relaxation times of the Debye and the low-frequency dispersions on temperature dependence.
