集合中的第一个点位于等于区段长度的第一段距离内。

The first point in a set lies at a distance equal to the segment length.

我也将根据比赛距离进行切分，因为比赛应用程序包含不同长度和不同参赛者的多项比赛。

I'm also going to shard based on race distance, because my racing application holds myriad RACES of different lengths, along with myriad runners.

这些线段的长度就是距离。

So these distances are the lengths of these line segments.

So, when we think about a bond length, this is going to be the length of our bond here, that makes sense because it's going to want to be at that distance that minimizes the energy.

因此，当我们考虑一个键的长度的时候，这就应该是我们的键长，这是合理的,因为体系会在核间距达到这一距离时,能量到达最小值。

And we can also talk about the bond length, so we might be interested in what the bond length is, what the distance between these two nuclei are.

另外一点就是键长，我们对键的长度也感兴趣，也就是两个原子核之间的距离。

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
