A Primer of Diffusion difficulties A Primer of Diffusion difficulties is a concise and energetic creation to diffusion thought in its many guises and to a number of analytical and numerical tools for the answer of diffusion difficulties. It discusses the diffusion equation, the regular country, diffusion below exterior forces, time-dependent diffusion, and similarity, hence bridging mathematical and actual remedies of diffusion. Featured themes contain a cautious improvement of the oxidation concept of silicon, houses of the relations of mistakes capabilities, precipitation and section variations, a concise creation to Laplace transforms, and nonlinear boundary stipulations. workouts are came upon in the course of the textual content, and appendices deal with not often stumbled on complex subject matters.
