一、前言荧光 X 射线是由原子内层电子跃迁所产生的,一般固有荧光 X 射线光谱的能量和轮廓随原子序数发生单纯的变化,每个元素均有固定值。但是,当元素的化学结合状态(例如:结合元素的种类,化合价、配位状态、晶形构造等)不同时,由于价电子层的 I. INTRODUCTION Fluorescent X-rays are produced by electronic transitions in the atomic layer. The energy and profile of a common intrinsic fluorescence X-ray spectrum change simply with the atomic number, and each element has a fixed value. However, when the chemical bonding state of an element (for example, the type of bonding element, the valence, the coordination state, the crystal structure, etc.) is different,
