摘要：

The effect of pressure up to about 2 kbar on the dielectric properties of Ice I at - 23.4 degrees has been measured. The static dielectric constant increases with increasing pressure by about the amount predicted by the Kirkwood theory. The increase in relaxation time yields a volume of activation for the relaxation process of 2.9 +/- 0.2 cm(3) mole(-1) which supports current views that dielectric relaxation occurs by rotation at orientational defects. The volume of activation given by the rapid rise of dc conductivity with increasing pressure is -11 +/-similar to 3 cm(3) mole(-1) which is consistent with the proton-transfer mechanism.
