摘要
按拉格朗日函数L =-g(λR +αRμνRμν +βR2 -Lm)的高导数引力理论研究力学系统的引力波问题 .在α>0 ,α +3 β <0的条件下 ,求出了双星和线性四极振子激发的引力辐射波 ,其结果当耦合常数α→ 0 ,β→ 0 时 ,与Einstein引力理论的结果相同 .
The problems of the gravitational waves for the dynamic systems are studied in the higher-order theories of gravitation with Lagrangian L=-g(λR+αR μν R μν +βR 2+L m). In the case of α>0 and α+3β<0, the gravity radiating waves of the binary stars and the linear quadrupole oscillator are found. The results are the same as that of the Einstein theory of gravitation when α→0 and β→0.
