conservation law

基本解釋

What Noether discovered is that whenever nature displays a continuous symmetry, a conservation law comes along for the ride, and vice versa.
（德國數(shù)學(xué)家） Noether 所發(fā)現(xiàn)的是，衹要在自然界呈現(xiàn)連續(xù)對(duì)稱性（的地方），守恒定律就一定成立，反之亦然。

All right, now what we're going to learn next time and Bob Field is going to teach the lecture next time, is how heat and work are related, and how they're really the same thing, and how they're related through the first law, through energy conservation.
這節(jié)課就到這裡,下節(jié)課將由Bob，F(xiàn)ield講授,我們將學(xué)習(xí)功與熱量的關(guān)系，認(rèn)識(shí)到它們?cè)诒举|(zhì)上的相同之処，竝通過熱力學(xué)第一定律，亦即能量守恒定律，把它們聯(lián)系起來。
