(Choral music) On a cold and gray morning, German Chancellor Angela Merkel and French President Nicolas Sarkozy together rekindled a flame before the Tomb of the Unknown Soldier near the Champs Elysees.
VOA: standard.2009.11.11
There is something that one might be able to hold on to: the knob of something, the little flame of something that ; The grain of sand. -The grain of sand; but there is really not a decent metaphor for it, I think.
一个你可以依靠的支点:,一个不同寻常的想法,一个思想的小火花,就像一粒沙中看世界,-一粒沙中看世界;,不过我认为任何比喻都不够贴切。
Or I could have a non-adiabatic, I could take the same temperature change, by taking a flame, or a heat source and heating up my substance. So, clearly q is going to depend on the path.
也能改变温度,绝热指的是没有热传递,在非绝热条件下,也同样可以升温,比如用火或者热源加热,这样,q也应当与路径有关。
