For turbulent support, we find the slopes of E_turb_-R_clump_ (turbulent energy and radius of the clump) and P_turb_-R_clump_ (turbulent momentum and radius of the clump) have no difference and are consistent with expected values whether there is outflow feedback in clumps or not. The ratios of the outflow energy and momentum to the turbulence energy and momentum (E_flow_/E_turb_, P_flow_/P_turb_) show that the majority of clumps have not enough energy and momentum to support turbulence. Meanwhile, there is no correlation between the velocity dispersion and radius. For potential disruptive effects, we conclude that it is impossible for the outflow activities to disrupt entire clumps and as the mass of the clumps increases, the clumps becomes harder to destroy. Finally, we do not see evidence that the virial parameter changes significantly whether the clumps have outflow candidates or not. Description: Li+ (2019, J/MNRAS/488/4638) searched for outflows toward 694 star-forming regions and identified 188 high-mass outflow candidates. Those candidates were identified by checking the velocity bulge of HCO+ PV diagram. The bipolar outflow candidates account for 74% of all candidates. The outflow parameters of 105 clumps with suitable bipolar outflows and reliable distances are obtained.
