In this paper, a Scalar Eelativiatic Green's Function method (SRA-KKR) neglecting spin-orbit coupling effect has been proposed for the energy band calculation.

略去自旋轨道耦合效应，在标量相对论近似下本文提出了一个近似的、相对论格林函数电子能带结构计算法。

Flexible topology and coupling structures are used to realize transmission zeros, thereby enhancing the stop band rejection or making more flat group delay.

这种滤波器采用灵活的拓扑结构和耦合结构，可以实现传输零点，从而提高滤波器带外抑制特性，或者使群时延更加平坦。

With a super regenerative receiver, this causes problems in that while close coupling improves sensitivity, it can cause the receiver to stop oscillating over part of the band.

与一个超级再生的接收器在一起，这引起那的问题当接近的联结改良敏感的时候，它能引起接收器遍及乐团的部份停止振动。
