例句與造句

1. The results indicate that compared with the antenna without reflecting structure , the proposed antenna achieves broader impedance bandwidth , increases the forward radiation gain and has stronger backward radiation suppression
   結(jié)果表明，與沒有地平面反射結(jié)構(gòu)的天線相比，該印制偶極子天線增加了抗帶寬，提高了前向輻射增益，抑制了后向輻射。
2. The result shows that the pbg structure has obvious character of forbidden band at the suitable size , and can be designed to good performance microwave filter . the pbg structure have the character of high resistance , that can reinforce the forward radiation , and reduce the backward radiation , increase the directivity , improve the gain and ameliorate the performance of the antenna . in addition , the pbg structure can also greatly increase the isolation and significantly decrease the coupling between the antenna elements
   研究結(jié)果表面，取合適的尺寸時(shí)， pbg結(jié)構(gòu)具有明顯的禁帶特性，可以設(shè)計(jì)成性能良好的微波濾波器； pbg結(jié)構(gòu)具有高阻特性，把這種特性用于微波天線時(shí)， pbg結(jié)構(gòu)可以加強(qiáng)前向輻射，減小后向輻射，增大天線的方向性系數(shù)，從而提高天線的增益，改善天線的性能，另外， pbg結(jié)構(gòu)還可以大大提高天線單元之間的隔離度，顯著減小天線單元間的耦合。
3. It's difficult to find backward radiation in a sentence. 用backward radiation造句挺難的
