摘　　要：Statistics of apparent collimation factors for molecular outflows catalogued is presented.Intrinsic collimation factor is calculated with the project effects removed.There is collimation difference between high and low mass outflows.It may concern the stellar sources in the flow regions,the outflow driving process,and the evolution time.
