Faults , breakpoints , and the triassic reflection configurations are readily recognized 断层、断点可靠,并有清楚的三叠系反射结构。
To broaden the antenna ' s impedance bandwidth and its radiation pattern , a novel printed dipole antenna with reflecting structure of v - shaped ground plane was proposed 摘要为了扩展天线的阻抗带宽和改善天线的方向性,提出一种采用了地平面反射结构的新型印制偶极子天线。
The general thickening from the southwest towards the northeast and north , combined with increasing of fine clastic to the northeast and north , indicate principle source of the upper kongdian formation from the southwest and south 自南而北地层逐渐加厚、细粒沉积物含量以及地层内部反射结构表明孔店组沉积时期物源来自研究区南部。
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 结果表明,与没有地平面反射结构的天线相比,该印制偶极子天线增加了抗带宽,提高了前向辐射增益,抑制了后向辐射。
Based on the enlarged waveguide y - branch , we introduced the sheared y - branch tir structure . after analyzing the structure parameters of the sheared asymmetrical y - branch , the extinction ratio of the tir optical switch can be more than 40db in theory . by wet erode , we finished photon - induce total internal reflection y branch optical switch with gaas material 在展宽型y分叉的基础上,提出了隔离型非对称y分叉全内反射结构,通过对隔离型非对称y分叉的结构参数的分析,在理论上可以设计出消光比达到40db以上的全内反射型光开光。
