radial velocity的意思
radial velocity中文翻譯:
[天]徑向速度
radial───n.子午線輪胎;輻射道路;鰭輻骨;星形發動機;adj.輻射狀的;(身體)中心區域的;橈骨的
velocity───n.【物】速度
velocity profile───速度剖面(圖),速度分布圖,速度變化圖
radial symmetry───徑向對稱,放射對稱;輻射對稱;[數]徑向對稱;放射對稱
muzzle velocity───初速;出口速度;初速度(彈出膛時的速度)
radial tubeless───徑向無內胎
constant velocity───常速度,等速度; 恒速;勻速;等速度;恒速度
angular velocity───[力]角速度
secondarily radial───二次徑向
this component, v cosine theta - which we call the radial velocity-- that is minus 100 kilometers per second.───這個成分,是vcosθ,我們叫做徑向速度-,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,科學家測量了由于行星的引力拖拉而產生的恒星擺動,這就是徑向速度。
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,近年來天文學家通過徑向速度法去發現或證實大量小到只有幾倍的地球質量的行星。
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個紅矮星已知擁有行星伙伴,并且都是通過視向速度技術發現的。
So by detecting the change in frequency between the transmitted and the received , the radial velocity of the target can be calculated.───因此,通過檢測之間的傳輸和接收頻率的變化,可以計算出目標徑向速度。
Earth-sized worlds in Earth-sized orbits aren't massive enough to make a radial velocity signal that's detectable with present technology.───在地球軌道大小的軌道上運行的地球大小的行星,其質量不足以產生當今技術可以檢測的徑向速度信號。
No proper motion and radial velocity determinations are available up to date.───目前尚無自行或視線速度的測定。
the thickness of jet flow along the wall is thinner and the radial velocity increases continually.───附壁射流區厚度變薄,附壁射流區內的徑向速度持續增加。
Synchronously, a numerical method is proposed for computing the precise radial velocity of the mover simply but effectively.───同時,提出一種數值計算方法可以簡單有效地計算出目標不模糊徑向速度。
