也可用作辐射口径，通过改变磁化场方向和强度实现波束扫描或极化变化。
3) multiple-aperture radiation element
多口径辐射单元
1.
The structure of multiple-aperture radiation element is a closed cavity which can t be processed with normal machining method and have to be disparted to several parts.
多口径辐射单元结构是一个封闭的腔体,采用常规的机械加工方法无法实现,必须将其分解成几个结构件分别加工,再将其连接成腔体。
4) transmission aperture
辐射孔径
1.
By changing transmission aperture and adjusting delayed time of electric excitation signal applied to every transmission elements,not only can the variable focal length be obtained,but also the same acoustic power can be kept in every focusing position.
通过改变每个圆环的激励信号延迟时间和辐射孔径,实现动态聚焦,并且保持聚焦处声强度一致。
6) radiation radius
辐射半径
1.
A new strategy is proposed——the radiation radius of nodes in static Ad-hoc network is different, so every node can adjust its radiation radius to construct directional link between nodes, thereby static Ad-hoc network can control the network topology in order to economize energy.
将遗传算法引入到了静态Ad-hoc无线网络的拓扑结构控制中,突破了网络中所有节点辐射半径都相同的固有思路,通过调节各无线节点的辐射半径,在相邻节点对之间形成有向路径,从而达到节省节点能源消耗和网络拓扑结构优化的目的,并取得了较好的实验结果。
