摘　　要：The visible spectroscopic and near infrared photometric data of the Be star γ Cas were obtained on November 5,6 and 9 of 1992. Total of 13 profiles were obtained, with a reciprocal dispersion of 2.7Amm^-1 in H_αand HeI 6678 region. The profiles for H_αand HeI 6678 of γ Cas are shown in figure 1,2 and 3, respectively.The results of the measurement in table 1 and 2 suggest that there are rapid variations in H_α and HeI 6678 emission feature. In figure 2 it is clear that there is a systematic trend indicating a red shift in latter profile relative to early profile.
