Let's start. Here is the zero. This is energy zero.

开始吧，这是0，这是能量。

And the idea was for a system with a finite number of - states. The idea was so let's say, the way we had it before, there was one state with energy zero.

这是对有有限状态数的系统的想法，想法是，那么比方说，我们之前采取的方法，有一个状态对应的能量为零。

It's much more relevant to set our zero point energy as the separation of a bond in terms of talking about the reactions that we'll usually be dealing with here.

更好的是把零点能定在,键断裂的时刻,在讨论化学反应的时候,而我们以后将经常遇到化学反应。

You know, if you want to measure the potential energy of something in a gravitational field, you have to define the zero somewhere, right, because it's arbitrary. You can set it anywhere you want. It's the same with enthalpy.

你知道，如果你想测量重力场,中某种东西的势能，你需要，在某处定义一个零点，对吧？,因为势能的值是任意的,你可以把它设定在。

The gap between the concept and the reality of net zero energy buildings seems largely a result of the shortcomings of most net-zero energy strategies.

FORBES: Walgreens Wagers on Net-Zero Energy

When completed, it will be one of the first net-zero energy and net-zero water-waste buildings in the country.

FORBES: See green

By focusing on renewable energy technologies rather than low carbon energy technologies, the net zero energy building agenda seems more like an exercise in futility than a serious challenge the risk of catastrophic climate change.
