Then , we discuss the influences that the ground screen acts on the equispaced linear array and the circular array respectively 然后我们分别讨论地网对于等间距线性阵列和圆阵列的影响。
2.
For the instrument system , we introduce effective steps and technique of screen or grounding screen that can restrain the great mass of interference 针对仪表系统，介绍了能有效抑制绝大部分类型干扰的屏蔽和屏蔽接地措施和技术。
3.
To prove the result , we simulate the coupling currents of the ground screen with supernec , and analyze the effects of coupling currents on pattern in quantity 为此我们使用supernec电磁仿真软件计算出了地网的耦合电流,验证了这一结论。
4.
The ground screen is utilized to obtain enhanced mirror affect , yet due to the disequilibrium of the electricity feeding , the coupling loses balance , which results in a shift of zero point of the vertical pattern 地网的作用是使地面能够起到更好的镜像作用,但是由于线性阵列相对于地网结构而言馈电不均衡,导致了耦合的不均衡,结果是使得线性阵列的垂直面方向图零点产生了偏移。
