光速测量 [guāng sù cè liáng]
light velocity measurement
- 光速是测量距离和测量时间的天然连接线。
is the natural link between distance and time measurements. - 例如，地球与月亮之间距离的测量精确度能做到小于一英尺，光速的测量可以精确到每秒小于千分之一英里。
For example, the distance to the moon was measured to within a foot, and the speed of light was measured to within a thousandth of a mile per second. - 对CG-Ⅲ型光速测定仪的测量方法作了改进，通过实际测量的结果表明，该实验方法改进后，光速测量的精度有了很大提高。
The method of velocity of light measuring with the CG-III of light velocity apparatus is improved, the measuring accuracy is increased significantly.
