摘　　要：通过对机车出现故障前的光谱数据分析,总结和归纳数据异常的特征,并对其进行分类,明确各类型的特征和扣检时机,形成数据分析的参照样本,从而指导数据分析,以减少漏报和误报的发生,是光谱分析标准的细化和重要补充。By analysing,summarizing and classifying the spectral data before the main bearing shell being crushed down,the data distinction,and so the opportunity for detaching for repair have been determined and the reference template for date analysis been developed for guiding fault prediction.The research results are benefical for drawing up the spectral analysis standards.
