目前为止，对PSR1913+16致密双星辐射阻尼效应的观测，仍然是引力波存在性的唯一间接证据。
At present, the observation of PSR1913+16 is the only available proof of gravitational wave, even though merely an indirect evidence it is.
结果表明圆柱壳部分覆盖阻尼层后，由于声漏效应，壳体声辐射与光壳相比会增强。
Numerical results showed that if the shell was partially covered wi th a damping layer, its sound radiation would be greater than that of the ba re shell due to leak effect.
