英文摘要	A set of close binaries was observed using the same instrumental configuration at Kitt Peak National Observatory. The rotational velocities of 99 components in 75 binaries are determined by two methods, including 55 stars for the first time. A list of some main physical parameters of the components is compiled from many sources. On this basis? two rotational parameters, the synchronous rotation velocity (V-e sini)(syn), the instantaneously synchronous velocity at the periastron (V-e sini)(e), are calculated. The statistical relations between the synchronization and the fractional radius, period are presented. For 48 early-type "normal" components of detached binaries which are believed to be the best samples for checking synchronism theories, we estimate their ages. Calculate their synchronization time scales from Zahn's dynamically tidal theory. Basically, we find that the theoretical predications of Zahn's synchronization mechanism are substantially compatible with the observation data.
