1. 以太波：ether drift 以太漂移 | ether wave 以太波 | ethoxyline 环氧树脂
2. 电磁波;以太波：ether starting aid 乙醚启动装置 | ether wave 电磁波;以太波 | ether 醚
3. 以太波,电磁波：ether vapor concentration scale ==> 乙醚蒸发浓度计 | ether wave ==> 以太波,电磁波 | ether-air anesthesia apparatus ==> 乙醚空气麻醉机
1. We remember that the velocity of light in vacuo, or in other words, in ether, is 186, 000 miles per second and that light is an electromagnetic wave spreading through the ether.
我们记得在真空中，或者说在以太中，光的速度是3.0×10^5公里每秒，而光就是在以太中传播的电磁波。
