摘要In this paper, we investigate if K-correction has strong impact on the alpha(ro) - alpha(ox) color-color diagram of BL Lacertae objects and obviously affects the classification of the objects. A sample consisting of the three kinds of the objects, those of low energy peaked BL Lacs (LBLs), high energy peaked BL Lacs (HBLs), and intermediate BL Lacs (IBLs), with all the values of radio, optical and X-ray fluxes and redshift available for the sources, is employed. We calculate the indices alpha(ro), alpha(ox) and alpha(rx) in both cases of K-correction and no K-correction and compare the results. The results show that: (1) for dividing BL Lacertae objects into three classes, LBLs, HBLs and IBLs, the effect of K-correction is negligible; (2) for classification, only a few of the objects may be affected by the effect.
