A 2-D coded GA is proposed to design the matching network composed of lumped components. The topology and component parameters of the matching network are optimized simultaneously. The network optimized by employing the 2-D coded GA shows better frequency response compared with the network synthesis method and the real frequency method. The thesis also employs the GAs to microwave measurement.

为了解决宽带匹配网络的设计问题，提出了一种二维结构的编码方案，采用这种形式的编码同时对网络结构和元件参数进行优化，成功地设计出性能优良的匹配网络，通过与综合法、实频法的设计结果相比较，表明遗传算法设计出的匹配网络性能更优，特别是在寻找新的网络拓扑结构方面，遗传算法具有更大的优势。

We have no common name for a mime of Sophron or Xenarchus and a Socratic Conversation; and we should still be without one even if the imitation in the two instances were in trimeters or elegiacs or some other kind of verse--though it is the way with people to tack on 'poet' to the name of a metre, and talk of elegiac-poets and epic-poets, thinking that they call them poets not by reason of the imitative nature of their work, but indiscriminately by reason of the metre they write in.

索夫农 、森那库斯和苏格拉底式的对话采用的模仿没有一个公共的名称；三音步诗、挽歌体或其他类型的诗的模仿也没有——人们把&诗人&这一名词和格律名称结合到一起，称之为挽歌体诗人或者史诗诗人，他们被称为诗人，似乎只是因为遵守格律写作，而非他们作品的模仿本质。
