coupling line meaning in Chinese

车钩连接线

Many years ago i wrote a couple lines of poetry
多年前我写了这些话：
The research is focused on the influence of the size of the coupling port , coupling line and the capacitive metal rods in cutoff waveguide on the gap impedance
研究结果表明：模双间隙腔连接截止波导段的耦合口的尺寸主要影响输出腔的外观品质因数，而耦合接头的粗细和电容性销钉的大小和插人深度对截止波导滤波器的调谐具有重要影响。
The result shows that , the size of the coupling port has strong influence on the external quality factor of the output cavity , while the size of the coupling line and the capacitive metal rods mainly affect the tuning frequency of cutoff waveguide filter
另外，由于耦合接头相当于在截止段中引人了一个附加电感，这使滤波器谐振电路的品质因数变大，谐振峰变窄。
Since the coupling line brings about an additive inductance in cutoff waveguide filter , which makes the quality factor bigger and resonant band narrower , it - mode double gap cavities are not more advantageous to achieve wider band than the single gap cavities loaded by cutoff waveguide filters
因此，模双间隙腔加载截止波导滤波器型输出回路并不比单间隙腔加载截止波导滤波器型输出回路有更好的带宽优势。
