摘要
X射线装置已被证实具有揭示物质的分子或原子特性的能力,这种特性对于探测违禁品是相当重要的。尽管X射线探测方法作为一种自动探测违禁品的有效手段已经开始商业化,然而大多数技术还不是很成熟。R是与有效原子序数直接相关的量,通过推证R值算法来获得被检物质属性,进而找出危险品的存在。
X-ray devices have demonstrated the ability to characterize a material at the molecular and atomic level. This ability is particularly important for detecting illicit materials. As X-ray detection methods which have increasingly been as an effective means for automatic detection of illicit materials now commercially available, most of these technologies are not yet mature. The purpose of this research has been to R methods for using X-ray dual-energy transmission technologies more effectively.
