When possible, try to maintain a single system ground point.
如果可能，应尽量采用单一的系统接地点。
The cure for such ground loops is to ground all equipment at a single point.
解决这种地回路问题的方法是将所有的设备在一个单点接地。
Operation mode can be divided into the upper and lower control and ground single control, but also point up point drop, multilayer control.
操作方式可分为上下控制和地面单人控制，也可点升点降、多层控制。
In many cases the resulting ground screen will be tied to chassis ground at a number of points but it will sometimes be better to join them at a single star point.
不过，某些应用里，还是先把它们接起来然后单点接地（译者疑虑，不一定要接机壳吧）效果更好。
The conclusion is that ground temperature should be measured by stick-shaped sensors of small size and, single point sampling should be substituted by averaged multiple point sampling.
地面温度应用体积小棒状传感器的多点采样平均来代替单点一次采样；
The easiest way of accomplishing this is to use isolated power sources and instruments, then find a single, good earth-ground point for the entire system.
实现这一点的最简单的办法是使用隔离的电源和仪器，然后为整个系统找出一个单个的、良好的大地接地点。
