as the reactant of conversion with respect to time. Assuming that curing of PCS fibers in air is a first-order chemical reaction, the kinetics equation can be written as ..., initial, final concentration of Si─Y, respectively. Because the determination of the concentration of Si─Y is difficult, the mass gain in percentage is used in the kinetics equation. Then the first-order......

, a rate equation is derived to describe the kinetics of internal oxidation of plate: X=k[KF(]t[KF)], where X is the oxidation depth, t is the oxidation time. For the internal oxidation of Cu-Al alloys..., and the research on non-steady-state diffusion rate equation will be necessary in order to better describe the kinetics of internal oxidation. In the present research, the non-steady-state diffusion......
