Qualitative Analysis Method of X-Ray Fluorescence Based on Fuzzy Cluster Analysis

Through study of qualitative analysis of X-ray fluorescence,a qualitative analysis method of X-ray fluorescence based on fuzzy comprehensive judgment was proposed. Some key parameters were extracted from theory and experiment and fused by fuzzy comprehensive judgment. On the basis of the result of fuzzy comprehensive judgment,the probability of certain element existing can be gotten. Experiment statistics had proven that it overcomes limitations on judgment of a single parameter and improves the correct rate of qualitative analysis.
