最近发现的脉冲双星系统的引力辐射将导致其轨道周期P以一个速率减小，现在可以预测为P −1dP/dt= −（3 ± 2）× 10− 9 yr −1，如果唯一的轨道扰动是广义相对论性的起源。它表明，其他来源的周期变化可能不太重要。这一预测的准确性及其验证的可能性将在未来几年内大大提高。这是第一个可以检验广义相对论超越后牛顿近似的观测结果。
The emission of gravitational radiation by the recently discovered binary pulsar system will cause its orbital periodP to decrease at a rate which can now be predicted to beP−1dP/dt= −(3 ± 2) × 10−9yr−1 if the only orbital perturbations are of general-relativistic origin. It is shown that other sources of period change are probably less important. The accuracy of this prediction as well as the possibility of its verification will improve greatly over the next few years. This is the first observation that can test general relativity beyond the post-Newtonian approximation.
