摘　　要：本文介绍了自行研制的高精度X荧光分析仪的具体设计及其在考古中的应用。此仪器采用新型电致冷Si-PIN半导体探测器和放射性同位素源，在无液氮冷却条件下能够实现对样品的现场测量。通过对考古现场（金沙遗址）的实际应用发现，仪器一次可以同时完成5种元素以上，甚至多达十余种元素的定性、定量测定，其分析结果清楚明了，分析精度可达2％～10％。In this article the concrete design of self-developed high-accuracy X fluorogenic analysis instrument and its application in the archaeological studies has been introduced. The instrument has adopted new electric refrigeration Si-PIN semiconductor detector and radioisotope source. Without having liquid nitric cooling condition, it can realize the on-the-spot measurement to the sample, and the measurement can finish at least 5 kinds even reach more than ten kinds of elements＇ qualitative and quantitative determination at the same time. Its analysis result is clear and the precision of its analysis can be up to 2 %-10%.
