“line-of-sight velocity”的概念、定义、习题解题方法及翻译-物理辞典

单词	line-of-sight velocity
释义	line-of-sight velocity(radial velocity) The component of a celestial body's velocity along the line of sight of the observer. It is usually given in relation to the sun to avoid complications arising from the earth's orbital motion. Line-of-sight velocity is normally calculated from the Doppler effect on the body's spectrum, a redshift indicating a receding body (taken as a positive velocity) and a blueshift indicating an approaching body (taken as negative)
