In the ecliptic course of 32 Cyg in 1981 the authors took its spectra in both red and blue spectral regions by means of a grating spectrograph on the Cassegrain focus of the one meter reflector of Yunnan Observatory. They selected 20 plates, including phases of total eclipse and atmospheric eclipse of 32 Cyg, to determine the radial velocity of the K supergiant component of 32 Cyg. The results are in accordance with the calculated values by using Edward E. Guinan's orbital elements and lower than the calculated values by using K. O. Wright's orbital elements. The radial velocities obtained from different lines at the same multiplet on the same plate are different. It seems that the short period pulsation may exist in the K component of 32 Cyg.
