摘要In this paper, the historic light curves of BL Lacertae in the infrared (JHK) bands have been constructed from the published literature. Maximum variations of Delta J = 2.(m)29, Delta H = 2.(m)42, and Delta K = 2.(m)93 and average color indices of J - H = 0.78 +/- 0.11, H - K = 0.78 +/- 0.12; and J-K = 1.55 +/- 0.13 have been found. The relation between the color index and the brightness of the source and the correlation of color-color indices have been investigated. Our analysis shows that there is no clear correlation between the color index and the brightness, and the emission mechanism is non-thermal in the near-infrared.
