视差, 视位移
the apparent displacement or difference in the apparent position of an object when viewed along two different lines of sight, often used in astronomy to measure the distance of nearby stars
- Astronomers use stellar parallax to measure the distances to nearby stars by observing their apparent shift against more distant background stars.
天文学家利用恒星视差，通过观察附近恒星相对于更遥远背景恒星的明显位移来测量它们的距离。
- The parallax of an object viewed with one eye and then the other creates the perception of depth or 3D vision.
用一只眼睛然后另一只眼睛观察物体的视差会产生深度或3D视觉的感知。
- In surveying, the parallax in sighting between two points helps calculate the distance and elevation changes.
在测量中，两点之间视线的视差有助于计算距离和高程变化。
- As a spacecraft moves, the parallax of distant celestial objects helps determine its position and trajectory.
当航天器移动时，遥远天体的视差有助于确定其位置和轨迹。
- Astronomers use the parallax method to estimate the distances to nearby galaxies, enhancing our understanding of the vastness of the universe.
