波整形电路从核心电路的锯齿波得到其他想要的波形——方波，脉冲波，三角波。

Wave shaping circuits derive the other desired waveforms — square, pulse, triangle, etc. — from the sawtooth output by the core circuit.

莱吉尔波是一名有经验的记者兼前五角大楼官员，他建议道，大众更加相信共和党的政客发布清晰的命令，在战争变得令人失望时会坚持到底。

Les Gelb, a veteran journalist and former Pentagon official, suggests that the generals have more faith in Republican politicians to issue clear orders and stay the course when wars turn sour.

so, remember we can break up the total wave function into the radial part and the angular part.

记住我们可以把整体波函数,分解成径向部分和角向部分。

No matter where you specify your electron is in terms of those two angles, it doesn't matter the angular part of your wave function is going to be the same.

不论你将，这两个角度,取成什么值，波函数的角向部分,都是，相同的。

So, you remember from last time radial nodes are values of r at which the wave function and wave function squared are zero, so the difference is now we're just talking about the angular part of the wave function.

你们记得上次说径向节点在,波函数和波函数的平方,等于零的ｒ的处，现在的区别是我们讨论的是,角向波函数。
