摘要：

A mechanism is suggested allowing to understand the observed suppression of small gas bubble‐diffusion mobility in solids. On its basis an expression for the radius dependence of the gas bubble diffusion coefficient is obtained. For small gas bubbles this expression agrees with the values of bubble diffusion coefficients obtained in experiments on copper, gold, and uranium dioxide. For larger bubbles it transforms into the known expression which varies inversely as the fourth power of the radius. Copyright © 1979 WILEY‐VCH Verlag GmbH & Co. KGaA
