Mall officials say four out of ten people who visit have traveled long distances.

He chose the line so that--this is Gauss-- he chose the line to minimize the sum of squared distances of the points from the lines.

高斯选的这条线,所有点距离这条直线的平方和,是所有直线中最小的

A lot of times we talk about these kind of distances either in nanometers or in angstroms so we can say this is 70 angstroms.

我们在讨论此类的距离时,很多都用到纳米和埃米的单位,所以它的波长是70埃米。

Movement down a concentration gradient occurs fairly rapidly over short distances like a micron or so, like the size of a bacterium.

顺浓度梯度扩散在一微米左右的短距离内,相当迅速,一微米相当于一个细菌的大小

AM radio can be sent over larger distances, but the quality of the sound is not as good as a later kind of radio signal processing, called frequency modulation.

To get the best fitting line, you find the line that minimizes the sum of squared distances.

要找到最切合的直线,就是要使,这些距离的平方和最小

Since that's all been pushed out of the way by development, that means the food has to get shipped in from larger distances.

之后由于发展建设,耕地都不见了,这意味着食物要从相当遥远的地方运过来

And you can think about that if you think about a standing wave, for example, where you can have amplitude at many different values of x, so an amplitude at many different distances, but you also have areas where there is a amplitude.

你们可以想象一下驻波，在不同ｘ处,可以有不同的振幅，在不同的距离有不同的振幅，但在某些地方振幅等于０．

These details aren't important, it is described in your book, but the thing that is important to know is that diffusion occurs fast over short distances, but because of the physics of diffusion it occurs slowly over longer distances.

这些具体细节无关轻重,书上都有,重点是你要明白,距离越短扩散越快,由于扩散现象的物理特性,距离越长扩散越慢

That creates all sorts of social consequences that we'll talk about sustainability, with shipping water long distances, all the plastic involved, people's distrust of public water systems that's unfounded, and things like that are very interesting and have big public health consequences.

这就产生了很多社会问题,比如我们将要谈到的饮水污染问题,饮用水在长途运输的过程中,会受到各种塑料污染,还有人们对公用自来水系统,毫无理由地不信任,类似这些现象都很有趣,而且会导致重大的公共健康后果

Here are humans who had to walk long distances potentially to find the food, kill the food at great risk to themselves; inspiring a cascade of physiological effects that have to do with fear and arousal and things like that, not to mention all the calories one would burn doing this kind of activity.

这些人可能需要走很远的路,去寻找食物,冒着巨大危险,杀死猎物,人们耗费能量以激活一系列生理效应,用以战胜恐惧,引发斗志,更不用说人们在狩猎的过程中,消耗的卡路里量了
