元素成份分析在探矿、冶金、公安侦破等领域得到广泛应用。本文介绍一种比较实用的检测分析系统。它是计算机技术与X射线探测技术的结合,理论上比较成熟,技术上容易实现。根据粒子探测理论,物质受一定能量的射线的激发,就会产生与该物质性质有关的X射线——特征X射线。对该特征射线的能量和强度进行测量,便可探知对应物质的名称及其含量。下面给出一套金属含量测试系统框图,见图1。电子束轰击样品,产生的特征射线 Element composition analysis in prospecting, metallurgy, police detection and other fields have been widely used. This article describes a more practical detection and analysis system. It is a combination of computer technology and X-ray detection technology, in theory, more mature, technically easy to achieve. According to the theory of particle detection, the excitation of a substance by a certain amount of energy produces X-ray-characteristic X-rays related to the nature of the substance. By measuring the energy and intensity of this characteristic ray, the name of the corresponding substance and its content can be ascertained. The following gives a set of metal content test system block diagram, shown in Figure 1. E-beam bombardment of the sample, resulting in characteristic rays
