The results of numerical simulations of particles structure (ordering) and dynamics (diffusion constant) in a 'liquid plasma' state of strongly coupled dusty plasmas are considered. Static and dynamical properties of microparticle systems in the liquid state have been studied in experiments under microgravity conditions. The comparison of the experimental results with the results of numerical simulations of Debye systems was used to estimate the effective coupling parameter which governs particles structural and dynamical properties. This diagnostics tool allows one to estimate particle charge and plasma screening length which are very important characteristics of dusty plasmas.
