摘　　要：给出了一个包含89个B lazar的样本,用O rig in 7.0研究了样本源γ射线流量密度在高态、平均态、态及高态减之间的线性相关.结果显示,它们之间都有较好的线性相关(p<0.01),并且显示出一定的相关强弱的顺序规律.最大值与最大值减最小值差的线性关系最好,相关系数为0.936.最小值与最大值减最小值差的线性相关最弱,相关系数为0.471.对所得结果做了合理的解释,得出了如下结论:B lazarγ射线辐射由多部分构成,各部分有不同的辐射机制.A sample including 89 Blazars was presented by using Origin7.0,the correlations among γ-ray flux density in high state ,average state ,low state and the difference of high state subtracting low state were investigated. The results showed that there were good correlations among them,and their chance probability were all less than 10^-4 ,and those relations were regular. The correlation between maximum data and the difference of maximum data subtracting minimum data was the best（p（0. 01 ,r=0. 936）. The correlation between minimum data and the difference of maximum data subtracting minimum data was the worst ,and the correlation coefficient was 0. 471. There were conclusions that γ-ray emission of Blazar consists of many components, and there were different emission mechanism in different components.
