英文摘要	The IRAS and 2MASS associations for 193 T Tauri stars are identified in this paper. From the color-color diagrams and spectral index, it is found that the IR excesses for most samples are due to thermal emission from the circumstellar material, as suggested previously. It is also found that the IR excesses at IRAS region for few T Tauri stars and the near-IR excesses for some T Tauri stars are likely attributed to free-free emission or free-bound emission from the circumstellar ionized gas. Moreover, It is found in deredened J-H versus H-K color-color diagram that there is a slight separation in different spectral groups. The T Tauri stars locus equation in J-H versus H-K color-color diagram for our sample is also presented.
