Baryon acoustic oscillations 重子声学振荡
These so-called baryon acoustic oscillations offer another yardstick for measuring the expansion rate of the universe over time and putting limits on the value of dark energy.
这些被称为重子声学振荡的东西为测量随时间变化的宇宙的膨胀速度和对暗能量的值施加限制提供另一尺码。
During the 19th century, the theories of tidal and acoustic gravity oscillations were subjects of great interest.
