摘要
本文使用ED-XRF荧光能谱仪。利用金原子在X射线激发下所发射的L_β线和L_∞线的强度比值来识别样品是镀金的还是K金。同时,利用这个比值的大小来测定镀金层的厚度。可测镀金层厚度0～5μm。最大相对标准偏差15％。
The li fi intensity ratio method of ED-XRF is applied list inpxiish the plated gold from the karat gold and to nitirk; the thickness of the gold coating. The Interfere of Zn unrated.The ineasuring rang is between 0 . 5um.The RSD is
