该仪器使用径向速度法来搜索行星。
The instrument searches for planets using the radial velocity method.
但是，近年来天文学家通过径向速度法去发现或证实大量小到只有几倍的地球质量的行星。
But in recent years astronomers have used radial velocity to find or confirm a number of planets down to a few times Earth's mass.
行星越重，就越容易通过径向速度法侦测（本质上是行星引力对恒星的扰动）。
The more massive a planet, the easier it is to detect using radial velocity measurements (essentially the star's wobble as a planet's gravity tugs it).
径向速度法，即观察某颗行星环绕恒星的轨道所引起的恒星相对地球来往的速度变化。
The radial velocity method, which looks for changes in a star's velocity toward or away from Earth triggered by a planet's orbit around that star.
径向速度法，也被称为多普勒摆动技术，用于搜索恒星光线的摆动，它显示出来自轨道上运行的行星的万有引力。
Radial velocity, also known as the Doppler wobble technique, involves searching for wobbles in a star's light that indicate the gravitational pull of an orbiting planet.
这一行星寻找领域内的常见手段叫做径向速度法，需要极度精确的数据测量才能检测到行星对附近恒星的引力作用。
This common method in the planet-hunting world, called radial velocity, requires extremely precise measurements to detect a planet's gravitational pull on a nearby star.
