对双元氧化剂引起二元固溶合金在无外氧化膜条件下，发生两氧化剂分立内氧化层的现象作了重新审视，在摒弃前人某些假设并考虑可能出现的各种氧化膜结构的上，提出了理论模型可描述同时发生双元氧化与两者各自单独氧化时各氧化膜厚度之间的关系，双元氧化两内氧化层厚度比与它们的扩散系统系以及最活泼组元在界面富集的程序等，藉所提理论还讨论了迄今已报道的有关研究结果。
By remx.ing me appmximations used in previous theories, a new theoretical &el was developed for treating the simultaneous internal oxidation of binary solid-solution alloys by twoxidants, which induced fomtion of subsequent LMCI internal oxidation regions corresponding separately to the twoxidants but without forming external scales of the mt-noble cchnponent. ?he new theory is able to describe the main phenanena related with this kind of internal oxidation such as: the relation between the overall thickness of internal oxidation simultaneously by twoxidants and those produced by the twoxidants singularly; the ratio between the thickness of the twregions depends critically on the ratio between diffusion coefficients of the LMCI oxidants and the enricht degree of the mt reactive canponent in the internal oxidation by LMCI oxidants etc. Sane experimental results reported in the literature so far are also canmented in tern of the present theory.
