You will notice that in the schematic the negative rail has 0 voltage so that setup is essentially in single rail.
你会发现在电路图中负电压是0伏，所以结构本质上是单电压。
For example, choosing the negative rail as the ground reference may optimize the dynamic range of an op amp whose OUTPUT is designed to swing to 0v.
例如，选择负轨作为地参考也许能够优化一个输出可以至0运放的动态范围。
An operational amplifier that can maintain stability close to its negative, or ground, rail is an important asset.
运放维持接近其负极、地或轨的稳定性是很重要的指标。
The elevated light rail eases the traffic congestion, but also has brought a certain degree of negative impact to the urban landscape.
高架轻轨在缓解城市交通拥挤现象的同时，也给城市景观带来了一定的负面影响。
Depending on the polarity of an ESD event you apply to the circuit's input connector, its high-voltage spike discharges through diode D1A or D1B into the positive or the negative power-supply rail.
依靠ESD适用电路输入连接器的极性，其高电压放电通过二极管d 1a或d1b进入供电正向或负向电源。
