The main contents are presented here:1. The network’s extract method of filter, which has finite attenuation poles in S-plane and Z-plane, are presented in detail.
主要内容有:1.详细研究了滤波器的准确设计理论,提出具有有限衰减极点的滤波器网络在S和Z平面上的提取方法,使每段λ/4传输线的长度所对应的频率都大大高于滤波器通带的中心频率,从而达到滤波器的宽阻带和小型化要求。

Remember, partial f, partial x was obtained by y That means I am slicing the graph of f by a plane that is parallel to the x, z plane.
要记得,在这里的fx中,是作为常量保持不变的。,looking,at,the,situation,where,y,is,held,constant。,这是我用一个平行于xz坐标系的平面,横截了f,所得到的图形。
Yes? Yeah, so I'm saying when you fix theta you get only a half plane, not a full plane I mean, it goes all the way up and down, but it doesn't go back to the other side of the z axis. Why?
请说,所以我说当固定θ时,得到的是半平面,而非全平面,它布满z-轴的一侧,但从不延伸到z-轴的另一侧,为什么?
So PI bonds have electron density both above and below the bond axis, but they actually have a nodal plane at this z, this bond axis here.
键在键轴之上,和之下都有电子密度,但它们在z方向有节面,这是键轴的地方。
Um-hmm. So, it's going to be the y z nodal plane, or in other words, we can say it's any place where phi is equal to 90 degrees.
嗯,是yz平面,换句话说,是在phi等于90度的面。
