 note = {It has been known that the moisture diffusivity in some solids depends on moisture content.
For one-dimensional diffusion in a rectangular-coordinate and for radial diffusion in a sphere, a finite-diference method was described to obtain the numerical solution of the diffusion equations for moisture-dependent diffusivity, then the accuracy and convergence of the solutions were discussed. It was pointed out that the finite-difference method for the moisture dependent diffusivity had a fear of a contradiction in the light of the stochastic process theory as mentioned previous paper., 固体内の水分拡散係数は含水率に依存することが知られている。含水率依存性の拡散係数の場合の拡散方程式の数値解を得るために直交座標の1次元拡散および球の半径方向拡散に関する階差法が示され，解の精度と収束が検討された。この含水率依存性の拡散係数の場合の階差法は，既報で論じた確率過程論に照らして矛盾の恐れを持つことを指摘した。, Article, 富山大学工学部紀要，47, Page 149-155},
