We measure the velocity distribution of the strontium atomic beam directly by Zeeman scanning technology. The most probable velocities of atomic beam before and after Zeeman deceleration are 420 m/s and 60 m/s respectively. Zeeman scanning method is much convenient than other detect ways. Because of its direct fluorescence observation, it has a high accuracy relatively.
