煤的单位能量含量低于石油和天然气,而且会导致包括酸雨在内的一系列环境问题。
Coal contains less energy per unit of weight than weight than natural gas or oil; it is difficult to transport, and it is associated with a host of environmental issues, among them acid rain.
What people did is they said let's define a unit of energy that represents a unit charge accelerated across a unit potential difference, and let's call that the electron volt.
前人们所做的就是他们说让我们确定,一个能量单位用来代表一单位电荷,加速穿过形成的一单位电势差,我们叫它电子伏特。
Why don't we define a new unit of energy That isnear to what we have to measure?
