- All elements are radiating in phase, and the resultant wave front is perpendicular to the axis of the element array.
所有单元发射相位一致，合成的波前垂直于单元阵列轴线。
- This voltage must be in phase with the primary voltage.
这一电压必须同原电压同相。
- Each small peak in the carrier would travel to the right with the usual phase velocity.
载波中的每个小峰都以通常的同相速度向右方运动。
