摘要：
铁路的路外交通事故每年都为铁路部门和国家带来很大的损失,非常有必要研制出一套铁路路障视频监测系统,而图像处理和图像的监控技术就是研制这套系统的基础。综述了现有的图像处理和监控技术的主要技术和方法,以及图像检测技术在铁路路障监测系统中的应用和实现。

Abstract: This article introduced an X-ray fluorescence spectrometry method using K2SO4+Na2SO4 as carrier to detect chlorine,bromine and iodine in bittern.Selections of carrier,the analytic condition of element as well as matrix correction were also included.The detection limits of Cl、Br and I were 0.004mg、0.008mg、0.004mg respectively and precision(RSD%) of Cl、Br and I were 1.14、0.89、1.07 respectively.The method is accurate,simple and practical.It is a good method for detection of chlorine,bromine and iodine in bittern.
