1895年伦琴发现X射线之后不久,人们就开始研究化学元素与X射线的关系。但是,由于X射线萤光强度弱,记录困难,直到近二十年来,X射线萤光分析才得到迅速发展。现在,这种方法已成为一种卓有成效的仪器分析方法,广泛用于冶金、地质、玻璃、水泥、石油产品、环境保护,以及生物学和医学等领域。X射线分析几乎与被分析元素的结合状态 Soon after Roentgen discovered X-rays in 1895, people began to study the relationship between chemical elements and X-rays. However, due to the weak X-ray fluorescence intensity and the difficulty of recording, X-ray fluorescence analysis has not been developed rapidly until nearly two decades ago. Now, this method has become an effective instrumental analysis method widely used in metallurgy, geology, glass, cement, petroleum products, environmental protection, and biology and medicine. X-ray analysis is almost the state of the element to be analyzed
