Single particle transverse mass spectra and HBT radii of identical pion andidentical kaon are analyzed with a blast-wave parametrization under theassumptions local thermal equilibrium and transverse expansion. Under theassumptions, temperature parameter $T$ and transverse expansion rapidity $\rho$are sensitive to the shapes of transverse mass $m_\text T$ spectrum and HBTradius $R_\text{s}(K_\text T)$. Negative and positive correlations between $T$and $\rho$ are observed by fitting $m_\text{T}$ spectrum and HBT radius$R_\text s (K_\text T)$, respectively. For a Monte Carlo simulation using theblast-wave function, $T$ and $\rho$ are extracted by fitting $m_T$ spectra andHBT radii together utilizing a combined optimization function $\chi^2$. Withthis method, $T$ and $\rho$ of the Monte Carlo sources can be extracted. Usingthis method for A Multi-Phase Transport model (AMPT) at RHIC energy, thedifferences of $T$ and $\rho$ between pion and kaon are observed obviously, andthe tendencies of $T$ and $\rho$ vs collision energy $\sqrt{s_\text{NN}}$ aresimilar with the results extracted directly from the AMPT model.
