radial velocity信息详情
[天]径向速度
radial───n.子午线轮胎;辐射道路;鳍辐骨;星形发动机;adj.辐射状的;(身体)中心区域的;桡骨的
velocity───n.【物】速度
velocity profile───速度剖面(图),速度分布图,速度变化图
radial symmetry───径向对称,放射对称;辐射对称;[数]径向对称;放射对称
muzzle velocity───初速;出口速度;初速度(弹出膛时的速度)
radial tubeless───径向无内胎
constant velocity───常速度,等速度; 恒速;匀速;等速度;恒速度
angular velocity───[力]角速度
secondarily radial───二次径向
this component, v cosine theta - which we call the radial velocity-- that is minus 100 kilometers per second.───这个成分,是vcosθ,我们叫做径向速度-,等于-100,公里每秒。
Finally, scientists measure the star's wobble due to the planet's gravitational tug, known as the radial velocity.───最后,科学家测量了由于行星的引力拖拉而产生的恒星摆动,这就是径向速度。
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.───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。
Only 9 other red dwarfs are known to have planetary companions, and these were all discovered through the radial velocity technique.───只有其他9个红矮星已知拥有行星伙伴,并且都是通过视向速度技术发现的。
So by detecting the change in frequency between the transmitted and the received , the radial velocity of the target can be calculated.───因此,通过检测之间的传输和接收频率的变化,可以计算出目标径向速度。
Earth-sized worlds in Earth-sized orbits aren't massive enough to make a radial velocity signal that's detectable with present technology.───在地球轨道大小的轨道上运行的地球大小的行星,其质量不足以产生当今技术可以检测的径向速度信号。
No proper motion and radial velocity determinations are available up to date.───目前尚无自行或视线速度的测定。
the thickness of jet flow along the wall is thinner and the radial velocity increases continually.───附壁射流区厚度变薄,附壁射流区内的径向速度持续增加。
Synchronously, a numerical method is proposed for computing the precise radial velocity of the mover simply but effectively.───同时,提出一种数值计算方法可以简单有效地计算出目标不模糊径向速度。
