(1)在单次散射近似下，成功地实现了计算有机薄膜光电子角分布的理论方法。(2)成功地分析了有机分子束外延制备的各种薄膜的光电子角分布，给出了定量的分子取向角。(3)将上述分析方法应用于聚合物表面的研究，通过对光电子角分布的定量分析，确定了侧基聚合物表面的侧基取向。(4)角度分辨紫外光电子能谱结合理论强度分析得到的结果与其他表面敏感光谱的结果一致。

(1) A theoretical method for the calculation of photoelectron angular distributions from organic thin films was successfully performed in the single scattering approximation.(2) The photoelectron angular distributions from various thin films prepared by organic molecular beam epitaxy were successfully analyzed to give quantitative molecular orientation angles.(3) The above analysis method was applied to investigate polymer surfaces.The orientation of pendant groups at the surfaces of pendant group polymers was determined by the quantitative analysis of the photoelectron angular distributions.(4) It was shown that the results obtained by angle-resolved ultraviolet photoelectron spectroscopy combined with theoretical intensity analysis were consistent with those obtained by other surface sensitive spectroscopies.
