The time course of the process consisted of a lag phase, a swelling
phase and a shrinking phase. The temperature dependence of the duration of the lag phase tl was roughly described by the Arrhenius plot, and the slope for the logarithm of the time constant vs. the reciprocal of the absolute temperature was coincident with that of the viscosity coefficient of ethanol, suggesting that the permeation rate of ethanol into the core mainly determines the duration of the lag phase.英語フィールド
