Sensors detect when dust concentrations reach a critical level and then an electric charge energises the material sending a dust-repelling wave across its surface.

当传感器发现粉尘浓度达到了临界水平，就有一定的电荷促使该材料发出除尘波越过其表面。

Quiet, he ordered with a brisk wave of an upturned palm - I was breaking his concentration. Yes, he was in charge, alright.

他手掌向上很快挥了一下，悄无声息地发出了命令——我打断了他的注意力，是的，他确是头领。

On the right bank of the wide channel that constitutes the port of Santos, Brazil's biggest, the orange Wave awaits a charge of orange juice for delivery to New Jersey.

巴西最大港口桑托斯海港的右岸，停的是“橙波”号，等着装载橙汁运往新泽西州。

That's not a positive and negative charge, that's actually a phase, and that arises from the wave equation.

这不是指正负电荷，它是指相位，这是从波函数中得来的。
