“地弹”,是指芯片内部“地”电平相对于电路板“地”电平的变化现象。以电路板“地”为参考,就像是芯片内部的“地”电平不断的跳动,因此形象的称之为地弹(ground bounce)。
In the design of high-speed circuit, some question such as delay, reflection, attenuation, scattering, crosstalk, ground bounce etc will result in prominent signal pulse distortion, even though signal transmit a little distance.
在现代的高速电路设计中,经常会出现一些互连的问题如延迟、反射、衰减、散射、串扰、地弹等,即使是传输很短的一段距离,这些效应也可能会导致显著的脉冲畸变。

她用手指轻轻地弹著钢琴。
只要皮特先生弹琴,他就会专心专意地弹。
我屏住呼吸,她又马上试了一次,然后又更自信地弹快了一些,节奏还是很好。
I held my breath. She tried it tentatively again. Then she played it more confidently and faster, and still the rhythm held.
