In the past, signal between stationaryplatform and rotary platform transmitted by electronic slip ring in order to realize remote control.
早期，旋转平台间的信号传输与控制采用电滑动环旋转传输电信号来实现。

A familiar illustration is provided by the force upon a stationaryplatform while a uniform flexible chain falls upon it from a hanging position.
当一个均匀而柔软的链子从悬挂位置落到静止平台上时，作用在平台上的力提供了一个熟知的例证。

Reference memory—in which rats learned over several days to use extramaze navigational cues to find a stationaryplatform—was disrupted by dopaminergic lesions, but unaffected by cholinergic lesions.
