Abstract
    The theory and methods of the composition dependence on depth of surface by angular-dependent X-ray photoelectron spectroscopy(XPS)have been summarized.The quantitative calculating programs were achieved,which could calculate quickly and reliably chemical compositions and layer thickness of multi-layer structure surface.
