本工作是利用短寿命核素快速分析煤和煤灰中的微量元素。工作中使用双标准方法,选用Au、Mn作标准,数据处理采用自编计算机程序。特点是省时、省力,操作程序简单。辐照中子通量为1×10~(12)n/cm~2·s,样品重量为250mg,煤样辐照5分钟,灰样辐照2分钟,均冷却30分钟,测量6分钟。一个样品,通过一次测量可分析出近20种元素,所用分析周期不到1 This work is the rapid analysis of trace elements in coal and coal ash using short-lived nuclides. Work using double standard methods, the selection of Au, Mn for the standard data processing using self-computer program. Characterized by time-saving, labor-saving, simple operating procedures. The irradiated neutron flux was 1 × 10-12 n / cm ~ 2 · s, the sample weight was 250 mg, the coal sample was irradiated for 5 minutes and the gray sample was irradiated for 2 minutes, both were cooled for 30 minutes and measured for 6 minutes. A sample of nearly 20 elements can be analyzed by a single measurement with less than 1 analysis cycle
