英文摘要	We propose a scheme to identify the region for the hadron-quark phase transition in cold dense strong interaction matter (neutron star matter) to take place with astronomical observations. To study the property of the first-order phase transition in the matter, we take the sound speed as the interpolation objective to construct the equation of state of the matter involving the hadron and quark coexisting phase. We show the feature of the sound speed in the matter with two conservation charges and a first-order phase transition. With the maximum mass, the tidal deformability and the radius of neutron stars being taken as calibration quantities, the baryon chemical potential region for the phase transition to occur is constrained to a narrow range, and the most probable value of the phase transition chemical potential is found.
