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.
