There's still not nearly enough thermal energy to have a molecules up here. So what, was the derivative of the energy with respect to the temperature?
仍然没有足够的热能使分子上升到这儿,那么相对于温度得到的,能量又如何呢?
The high cost of wind turbines combined with limited, seasonal output still place wind power at a disadvantage compared to thermal power.
风机成本高,加上风力资源有限,季节性强,使得风力发电与火电相比仍处于劣势。
Change the temperature a little bit, still not enough thermal energy to get up there.
把温度改变一点,也没有足够的能量使分子跃迁。
