Water will often be pumped from the source to an elevated point to allow gravity-feed distribution. Planning of the site should take this into account.
通常采用的重力给水方式，需要用水泵从水源把水抽取到高处，在规划安置点时应当考虑到这一点。
The single feed point is coupled to a single source and the single feed point provides the signal to both the first conductor 102 and the second conductor 104.
该单一馈送点被耦合到单一源，并且该单一馈送点向第一导体102和第二导体104两者提供信号。
A first quarter wavelength portion extending in one direction from the signal source or feed point and a second quarter wavelength extending in the opposite direction from the signal source.
第一个四分之一波长部分在一个方向上从信号源或馈送点延伸，而第二个四分之一波长在相反的方向上从信号源延伸。
