perihelion

1. ( astronomy) position of a planet as defined by its angular distance from its perihelion ( as observed from the sun).
   从太阳观察到的行星距近日点的角度偏差。
2. The point in the orbit nearest the sun is called perihelion, while the point farthest is called aphelion.
   在轨道上最接近太阳的点被称为近日点，而最远离太阳的点被称为远日点。
3. He also figured out the planet goes faster when it's at perihelion, nearer the sun, than when it's at aphelion, its farthest distance.
   他还计算出地球在近日点（即距离太阳最近的点）比在远日点（即距离太远最远的点）运行得更快。
4. The anomalistic year is the time between successive transits of the Earth through the perihelion.
   近点年是地球连续两次通过近日点之间的时间。
5. When perigee and perihelion coincide tidal range is at its greatest.
   当月球与地球到达它们的近地点和近日点的时间恰好重合时，就会引起最大的潮汐。
6. Gravity waves and perihelion deflexion of light
   引力波与光线近日偏折
7. Using these equations of motion, we investigate some classical gravitational effects in dilaton spacetime, such as the bending of light rays, the perihelion advance of planet, the delay of radar echo, and the redshifts.
   利用这些运动方程，具体考察伸缩子时空的一些经典引力效应&比如光线弯曲，行星进动，雷达波的延迟，以及红移。
