摘要
本文对赤纬负10°以北的所有11颗硅酸盐碳星进行了近红外JHK观测．结合可见波段及红外天文卫星的观测结果，讨论了它们的红外双色图及能谱分布，并将其与正常碳星的结果相比较，进而讨论了它们的演化状态．
The JHK photometric observations of all silicate carbon stars with declinations > -10 °are presented in this paper. Combined with some observational results in the visible and IRAS regions, the two color diagrams and energy distributions of the silicate carbon stars observed are discussed. Furthermore, their evolutionary chalacteristics are also discussed.
