轨道半径 meaning in English
orbit radius
orbital radius
Examples
- The roche limit for the earth is a small fraction of the radius of the moon's orbit .
地球的洛希极限相当于月球轨道半径的一小部分。 - The acceleration may in turn be obtained from the velocity of the satellite and the radius of the orbit .
这个加速度又可根据卫星的速度和它的轨道半径来求得。 - Later simulations show that even a companion with an orbit as wide as neptune ' s could scoop up an accretion disk
后来的数值模拟结果显示出，即使伴星的轨道半径大如海王星的轨道，它仍可汲取物质而形成吸积盘。 - Roughly a sixth are “ hot jupiters ” surprisingly near their stars , all closer than mercury is to our sun
其中大概有1 / 6属于热木星型的行星，它们非常接近所绕转的恒星，其轨道半径也都小于水星到太阳的距离。 - For example , if there is a planet orbiting around the neutron star , it will wobble a little and the pulses will come a little early or late . we can then deduce the mass and the radius of the orbit of the planet from the arrival time of the pulses . this is how the first extrasolar planet is discovered
例如假若有一颗行星围绕一颗中子星运行，它会令中子星出现摇动，引致脉冲的间隔变长或短，由此我们根据脉冲周期的变化，可推断出行星的质量和轨道半径，这亦是天文学家找出第一颗地外行星时所用的方法。
