AbstractA long-term monitoring of 13 Be/X-ray binaries and 34 Be stars have been carried out with the 1.26 m reflector and the 2.16 m telescope at Xinglong Station. The observations cover the period of about 13 years in the optical spectroscopy and about 5 years in the near-infrared photometry. We present the monitoring results of two sources, X Persei and LSI +65 degrees 010, in the program. We detect changes of H alpha EWs and JHK magnitudes in X Persei which reflect the formation of the extensive and dense envelope. The JHK magnitudes increase and decay rapidly while the variation of the H alpha is wild. The behavior is suggestive of the envelope with different optical depth. The red-shift component in LSI +65 degrees 010 have been found in the monitoring program. The component may be brought from the neutron star with the movement in the line of sight.
