In public area, however, the "zero distance" is harmful.

然而，在公共领域里，“零距离”是有害的。

So, we just talked about the force law to describe the interaction between a proton and an electron. You told me that when the distance went to infinity, the force went to zero.

我们刚刚讨论了描述质子，和电子之间相互作用力的定律，当距离变为无穷时，力变为零，那当距离变为，零时会发生什么？

As you can see, I've added a zero to both Race_01 and Race_02's distance values.

如您所见，我对Race_01和Race_02的距离值都添加了一个零。

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

So, we just talked about the force law to describe the interaction between a proton and an electron. You told me that when the distance went to infinity, the force went to zero. What happens instead when the distance goes to zero? What happens to the force?

我们刚刚讨论了描述质子,和电子之间相互作用力的定律,当距离变为无穷时,力变为零，那当距离变为,零时会发生什么？,这时候力是多少？

The economics of offering TV channels are not the same as long distance (which has a marginal cost of zero more or less) and so there are clouds on the horizon.

FORBES: Are Cable TV Carriers Seeing Meaningful Subscriber Degradation Due To Young People Not Signing Up?

Thus a perfectly symmetrical face, with eyes, lips and nostrils exactly the same distance from the central line, would earn a score of zero.

ECONOMIST: Health indicators

If there were no correlation between prosperity and distance from the equator, we would expect the green line to be centered at zero with random oscillations due to noise in the data.

FORBES: The correlation is there.
