摘要
能量色散的X射线散射(EDXRS)技术是一种识别液体种类的有效方法。实验用毛细管X光半透镜代替狭缝,用能量色散的X射线散射技术进行液体种类的识别研究。实验结果表明,两个毛细管X光半透镜组成的准直系统,能显著地提高光源的X射线利用效率,提高散射能谱的分辨率等;毛细管半透镜组成的能量色散X射线散射方法是一种良好的液体种类和含量的识别技术,在液体的种类和含量的识别领域有广泛的应用前景。
Energy dispersive X-ray scattering （EDXRS） technique is an effective method for identification of sorts of liquids. In this experiment, the polycapillary X-ray half optics is used to replace the slits of the EDXRS to identify the sorts of the liquid samples. The experimental results show that alignment system consisting of the two polycapillary X-ray half optics can improve the efficiency of X-ray source and the resolution of the scattering spectrum. The EDXRS with polycapillary X-ray half optics is an appropriate method to identify the sorts and concentrations of liquids, and has a widely applications for the identification of sorts of liquids.
