Two different geometrical patterns of PET fibre were obtained in the x-ray diffraction camera. The isotropic scatting noncrystalline region was first separated. The scattering of the oriented noncrystalline zone was characterized by a selected function. And its extent in terms of whole reflection sphere was then calculated after a multi-peak-resolution process in a microcomputer.

A series of La1-xMxCoO3 (M = Ca,Sr) perovskite oxides have been synthesized and the change of surface states after the substitution of La3+ ion in LaCoO3 with Ca2+ or Sr2+ ion have been investigated by XPS technique. It is shown that the percentage of adsorbed oxygen obtained in the peak fitting of O1s spectra is regularly varied with the substitution content x. The peak fitting of Ca2p, and Sr3d spectra has been performed and Ca(2) and Sr(2) may be assigned to the situation that there exist vacancies of oxygen...

A series of La1-xMxCoO3 (M = Ca,Sr) perovskite oxides have been synthesized and the change of surface states after the substitution of La3+ ion in LaCoO3 with Ca2+ or Sr2+ ion have been investigated by XPS technique. It is shown that the percentage of adsorbed oxygen obtained in the peak fitting of O1s spectra is regularly varied with the substitution content x. The peak fitting of Ca2p, and Sr3d spectra has been performed and Ca(2) and Sr(2) may be assigned to the situation that there exist vacancies of oxygen surrounding them. The relationship between the percentage of Ca(2) or Sr (2) and the percentage of absorbed oxygen can be adoptd to explain the surface state change after substitution. Therefore, we reasonably assume that the substitution of Sr2+ causes an increase in vacancy of oxygen, however, the substitution of Ca2+ causes an opposite result.
