摘      要：We study phase behaviors of mixtures comprising active particles with and without active reorientation by varying mixing *** observe that the order parameter characterizing flocking in the steady state exhibits a linear decrease with an increase in mixing *** the order parameter characterizing clustering in the steady state presents a sharp leap as the mixing ratio ***,we obtain phase diagrams of flocking under different mixing ratios and observe that the domain corresponding to flocking experiences a contraction with the increase of mixing ***,the coordinates of the critical point on the phase boundary between the flocking and the disordered phase decay exponentially with the mixing ratio.
