增加三个正弦波可形成一个复合波。

The nonlinear wave shape degenerates to a sinusoidal wave.

所以，在微波和毫米波可逐渐用空间功率合成器来取代传统的集体功率合成器。

Therefore, within the bands of microwave and millimeter wave, the traditional integrated combiner can be gradually replaced by the space power combiner.

So, what this means is that when we're looking at an actual wave function, we're treating it as a wave, right, so waves can have both magnitude, but they can also have a direction, so they can be either positive or negative.

这意味着,当我们看一个波函数时,我们把它看做一个波，波不仅有幅值，还有方向，所以它们可正可负，如果。
