但要求这种“震动感应器”灵敏度要高，而且还能够判别震动的来源。
But the requirement that such "sensors" sensitivity must be high, but also to determine the source of vibration.
我们再来看一看“震动感应器”的工作原理：首先，金属棒就是用来感应路面上有无震动的。
"Now let's look at the" sensors "and it works: First, the metal rod that is used to sense whether the road vibration."
这种“震动感应器”是为节省能源而设计，希望这种装置能够应用到实际中去，发挥巨大的作用。
This "vibration sensors," is designed to save energy, hope that this device can be applied to practice to play a huge role.
