Using the observation data of ¹²CO(1-0), ¹³CO(1-0) and C¹⁸O(1-0) lines, and combined with the observation results of ATLASGAL (The APEX (Atacama Pathfinder Experiment) Telescope Large Area Survey of the Galaxy) dust continuum survey, the physical properties and kinematic characteristics of clumps have been studied in nine infrared dark clouds (IRDCs) in detail. Velocity range of infrared dark clouds are given. It is showed that the Spitzer 8μm radiation background corresponding to the infrared dark cloud is superimposed with the ¹³CO(1-0) and C¹⁸O(1-0) integral intensity distribution map basically consistent with the outline of the infrared dark cloud. Eight of the nine IRDCs present the filamentary structure. Totally, with 51 identified dense clumps in these infrared dark clouds, most of these clumps with large masses gather at the hub of infrared dark clouds. The obvious bimodal structure is shown in the mass statistical histogram, which further confirms the picture of matter transport in a fibrous molecular cloud. The typical excitation temperature distribution of CO in these clumps is between 10 K and 15 K. We find three clumps with blue profiles and five clumps with red profiles. There are 17 in different evolution stages associated with outflow candidates, so outflow should be common in clumps. The higher detection rate of outflow in MSF (Massive Star-Forming) and YSO (Young Stellar Object) clumps may indicate that the accretion in the process of star formation may increase with the evolution stage of star formation in the clumps. All of these clumps are gravitationally bound and tend to collapse. All clumps meet the basic physical conditions for the formation of massive stars. These early stage massive star-forming clumps at different evolution stages are ideal targets to study the massive star formation.
