Calculate on Gravitational Radiation of Compact Binary

With the Landau-Lifshitz' expression of energy-momentum press and the formula of quadrupole,the sources of gravitational radiation of some compact binary systems,were discassed, gravitational radiation of several compact binary systems (e.g. binary PRS1913+16,bi-stars PSRJ0737-3039A/B and binary black holes) were calculated. Comparing with the theoretic results and the that of observation,it is found that there be a agreement between the observed data and theoretic results in accepting precision extent,and it show that the Landau-Lifshitz' expression of energy-momentum press and the formula of quadrupole surely be a good approximate way for research the emission of gravitational waves.13refs.
