您要查找的是不是：
- Multiple ground pins are important for another reason: they keep down the ground impedance at the junction between the board and the backplane. 在连接器里设置多个地线引脚还有别的好处：降低插板和背板间的地线阻抗。
- The influence of lossy ground was included by using the Sunde approximation equation when dealing with the diagonal and off-diagonal ground impedance terms. 给出了一种类似“状态转移矩阵”表达的方程解的形式，并以相模变换的方法推导了解的具体表达式。
- The best way of minimizing ground impedance in a multicard system is to use another PCB as a backplane and have a ground plane( or even two- one analog, one digital) on that mother card. 为了降低多板连接的地线阻抗，最好的办法是专门设计一块背板（板）并且背板上要设置接地面（至设置模拟地和数字地两个接地面）此外，在背板与子板的连接器里要留出尽量多的引脚用于接地。
- The basic principles still apply: ground impedance must be as low as possible, high level and low level signals must be separated so that they do not interfere with each other, and capacitance and mutual inductance coupling must be avoided. 前文提到的原理仍然适用：地线阻抗要尽量小，大功率信号和微弱信号要分开布置以避免串扰，一定要避免电容性耦合和电场耦合。
