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.

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？

Then, to measure, how much "wealth" the kids had gained from the candy, we asked them: On a scale of zero to 10, how much do you value your gift?

然后，测量这些孩子从他们的糖果所的到的满意度，我们要求他们从0到10评分，你将如何评价你的礼物？

Such current disturbs the zero out-put basic line of the light mass number region, so that it's very difficult to measure and record the height of spectrum peaks of the light mass number region.

这种电子流对轻质量部分质谱的零输出基线起干扰作用，致使这部分谱峰的峰高不能很好地测量和记录。

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。

So what we do is we pick an origin, call it zero, we put some markers there to measure distance, and we say this guy is sitting at 1,2,3,4,5.

我们现在选择一个原点,称其为零点,我们做一些标记来测量距离,这个点在五个单位长度的地方

If driving rates down to zero was, above all, a measure to combat deflation, the policy should be abandoned only when the threat of deflation is lifted.
