Then the design methods of the parallel coupling SIR band-pass filter has been discussed, and analysed the different characteristic of the SIR resonator with the different impedance rate.

之后，用SIR的原理讨论了平行耦合带通sir滤波器的设计方法，并分析了不同阻抗比的SIR滤波器之间特性。

While with a composite patch, there exists coupling effect between the normal stress parallel to crack and the SIF, and the coupling effect is significantly dependent on ply orientation of the patch.

而裂纹板经复合材料补片胶接修补后，平行于裂纹方向的拉压应力对裂纹尖端的应力强度因子具有耦合效应，并且这种耦合效应的大小与补片的铺层含量有很大的关系。
