In this thesis, cascaded electromagnetic band-gap structure is presented to broaden the bandwidth or achieve dual band operation. The structure is applied to antenna in order to restrain the backward radiation, decrease mutual coupling between units and eliminate scan blindness of phased array antenna.
本文提出级联型的电磁带隙结构,用以展宽其带宽或实现双带工作,并将其应用于天线,抑制天线的后向辐射,减小单元之间的互耦,消除相控阵天线的扫描盲区。
Scan the exposure X-ray images with UVP gel imaging analytic system to calculate the respective optical density ratio of bands represent objective proteins to band of GAPDH. Then we can get the variation tendency of each proteins. 5.
将曝光后X-ray照片用UVP凝胶成像分析系统进行扫描,计算各基因蛋白条带与内参GAPDH蛋白条带的光密度比值,推算各凋亡因子表达的变化趋势。
