You can take heat energy and convert it to work energy and vice versa, and it doesn't say anything about that you have to waste heat if you're going to transform heat into work.
你可以把热能便成功,也可以反过来,但它对于如果你要把热变成功,就必须浪费热量这件事只字未提,它只是说这是能量。
All right, so I'm burning some energy, I'm burning some fuel to do this somehow, to get that work to happen.
而这个路径需要先加热再冷却,这样,我需要能量来源,比如燃料,来完成做功。
Others carried out energy studies of city school buildings to make sure the equipment and systems work effectively.

Sometimes we might just directly tell you that's probably the easiest scenario, because when we think about work functions those are usually reported in energy.
有时候我们可能只是直接告诉你,那可能是最简单的情况,因为当我们考虑功函数时,它们经常用能量来记录。
Many people who work in fishing part of the year also depend on well-paid jobs in offshore energy.

And happier people are more successful, because they have more energy and work harder.
越快乐的人越成功,因为他们有更多精力,工作更努力。
But it is the energy of the artists and their willingness to share their work with others that makes the festival so interesting.

That is a maximum If you are sharing your time and energy during this period on Tuesday afternoons, or the arch-field don't work so think carefully about that.
让大家充分发挥自己的能力,如果每周二下午这段时间,你都有时间,精力也很充沛,就可以来上这门课,不过这样你就没时间参加实践活动了,所以请仔细考虑吧。
Mister Obama promised to work with them on important issues including energy development and climate change.

We would be then reaching to the EU, and saying: "Look, you got some oil, and you've also got possibilities of developing alternative sources of energy, We'll work with you.
我们主动和欧盟交谈,你们有石油资源,你们还有可能,开发可替代能源资源,我们想和你们合作。
It says it will work with manufacturers of high-energy products to try to improve energy use.

So the two points of interest of research are how does it work this conversion of mechanical energy into electrical energy how are we able to bring back lost hair cells to cure deafness.
因此这项研究的两个关键点,一是机械能,是如何转化成电能的,我们能不能通过修复受损的毛细胞,来治疗耳聋。
"UNASUR is doing some excellent work in integrating efforts in the region around things like energy and security.

It cools down because I'm doing work but the energy has to go somewhere, right?
因为膨胀过程中,对外做功?
He said the United States wanted to work with Europe on a new strategy that would provide energy security for the future.
VOA: standard.2009.10.23
So, we do this here for the photoelectric effect, and in terms of the photoelectric effect, what we know the important point is that the incoming photon has to be equal or greater in energy then the work function of the metal.
所以,我们做这个是为了说明,光电效应,在光电效应方面,我们知道的最重要的事情,就是入射的光子能量必须等于,或者大于金属的功函数。
"One lesson we need to work together toward is a more secure energy future.
VOA: standard.2009.10.23
There's an interplay between the energy inside the gas which is the heat energy which is allowing me to do all that work to be outside, and so I'm using up some of the energy that's inside the gas to do the work on the outside.
即使没有热传递,能量也能以,做功的形式传递出去,气体的一部分内能,转化成了功。
"Democrats and Republicans must still work together to make health care more affordable, invest in renewable energy and help all people in America to get an education.
VOA: standard.2009.04.28
We can also talk about it in terms of if we want to solve, if we, for example, we want to find out what that initial energy was, we can just rearrange our equation, or we can look at this here where the initial energy is equal to kinetic energy plus the work function.
初始能量是多少,也可以,写成另一种形式,我们可以把方程变形,或者我们看这里,初始能量等于,动能加功函数。
I have a lot to learn,". A senior U.S.official who attended the meeting said Mr.Obama expressed a desire to work with UNASUR nations to confront economic, environmental,and energy challenges.
VOA: standard.2009.04.18
That is, it gives us the relationship between energy and work and heat.
热力学第一定律阐述了,能量,功和热之间的关系。
that's not our goal," "What our goal has to be is to advance the clean energy solutions in this country that can strengthen our economy, put people back to work, diversify our energy sources."
VOA: standard.2009.06.02
So, now we can talk about it in different terms, Ei for example, talking about e sub i, which is the incident energy or the energy of the light that comes in, or talking about work function here, and that's just another way to say threshold energy.
现在我们可以从不同的方面,来谈论它了,举例来说,它是入射能量或者进来的光的能量,或者谈论这里的功函数,它是另一种描述临界能量的方式。
So, therefore, we can rewrite our equation in two ways. One is just talking about it in terms only of energy where our kinetic energy here is going to be equal to the total energy going in -- the energy initial minus this energy of the work function here.
所以我们可以把方程,写成两种形式,一个是,只考虑能量,动能等于总的,入射能量-初始能量减去,功函数的能量,我们如果想解决,比方说,我们想知道。
now we're not just talking about 1 photon, 1/2 let's say we shoot them all at the same time at our metal, each of them having some energy that's let's say 1/2 the work function. So, just to take a little bit of an informal survey, who thinks here that we will have an electron that is ejected in this case?
我们现在不仅仅讨论一个光子,它们所具有的能量是功函数的,我们在同一时刻把它们打到金属上,我们做一个不太正式的调查,谁认为这种情况下,一个电子会被打出?
And the first law says, well heat and work are different forms of energy, and we can add them, and the path dependence of these two things is somehow cancelled in the fact that we have this internal energy.
热力学第一定律说,热和功是能量的不同表现形式,我们可以把它们加起来,它们与路径相关的部分相互抵消,我们就有了内能。
And because there is an explicit relationship between u, delta u, q and w, you can always find the easy way to derive the change in internal energy or the heat or the work.
因为Δu,q和w之间,有明确的关系,一般来说,内能或热或功的变化,易于计算。
