monolithic system. dissolved active drug in matrix
desorption of drug can be expressed as early time and late time.
desorption from a slab with thickness of l can be expressed by
two series, which is derived in Crank's book "mathematics of diffusion".
现在找不到这本书，下周一需要交推导过程。哪位知道如何从建立模型到推出这
两个series的表达式。
大致为： Mt/Mo=1- infinite

没法表示清楚这个公式。大致意思吧。多谢多谢！ | b**s
