The Gibbs free energy. Notice, we could also write, let's rewrite that.
吉布斯自由能,注意,我们还可以这样写,重写一下。
What that suggests is that actually the simplest and most natural connection between Q and macroscopic thermodynamics is to the Helmholtz free energy.
这暗示我们,最简单最自然的联系,在Q和宏观热力学两之间,是和亥姆霍兹自由能的联系。
What this is telling us is that we just have a chemical potential, of Helmholtz free energy per molecule.
这告诉我们的是,我们只有化学势,每个分子的亥姆霍兹自由能。
Who remembers? Gibbs free energy?
有谁记得?吉布斯自由能?
So a pretty simple form for the Helmholtz free energy.
亥姆霍兹自由能的一个比较简单的形式。
Could it be that having all this free energy lying around in fossil fuels offered us a dangerous dose of cultural steroids, the evolutionary equivalent of human growth hormone?
难道化石燃料里的自由能对于我们的文化进化过程,就相当于危险剂量的类固醇类激素对于人类的生长一样吗?
An altogether different, and better, idea is to use the sea to generate green, CO2-free energy.
一个完全不同的更好的思路是,利用海洋产生绿色、无co2的能量。
