阻抗

When heavy hydrocarbon iso-octane was applied as the fuel,the cells with SDC modified anodes showed comparable performance and higher OCVs compared those with Ru as the anode catalyst reported in the literature using the same fuels.

阻抗谱显示在此期间电极界面极化电阻几乎不变，意味着最大功率密度稍微的下降主要来自于OCV的变化。

It is most likely that only a part of the karst caves could be detected if the boundary of the karsts cave has a certain horizontal extension respectively to measurement layout, but the interface of the karsts caves is not completely smooth plane, and its normal direction is not perpendicular to the tunnel axis.

如果溶洞的边界相对于TSP测量布线有一定的横向延伸性，其边界面不一定是完全平滑的表面，但其法线方向与隧道轴线不完全垂直，这类溶洞有可能被部分探测，但探测精度还与溶洞界面两侧的波阻抗差、对地下水的探测、操作人员的数据采集经验和数据处理水平等有关。

However, the precision of the cave detection is related to interface wave impedance difference of the karst caves, groundwater detection, operator's data acquisition experience and data processing level and so on.

The printed UWB antenna is comprised of a planar monopole radiator and the ground plane which are connected to a coaxial cable to launch RF signals. This kind of ground and antenna system is essentially an unbalanced design, where electric currents are distributed on both radiator and ground plane, and then leakage to the outer conductor of the feeding cable. The impedance matching and radiation pattern will be influenced in the low band, which are our focus. Finally, some techniques will be proposed to reduce the cable effect on the antenna performance.

进行超宽频天线量测时，吾人会利用同轴缆线连接到网路分析仪，这时的同轴缆线不只是扮演一个传输讯号的工具而已，由於单极天线的不平衡结构，对低频而言，接地回流电流会泄漏到同轴接地的导体外部，造成同轴缆线也是一个辐射体，影响到天线低频时的阻抗匹配与辐射特性，因此本论文将探讨同轴缆线对於天线一些参数的影响，并研究提出解决的办法。
