These include the meter for length, and the second for time.

包括度单位米和时间单位秒。

That's why knowing the length of the astronomical unit is so important!

这就为什么知道天文单位的度如此重要的原因！

D. It was an exceptional unit of length.

D. 这个特殊的度单位。

So, if you were to measure the British coast, using length of 100 km, you'd end up using 28 of them and get an answer of 2800 km.

所以，如果你测量英国的海岸时使用的公的单位度，你最终会测到28个，得到的结果就两千八公。

Today, Servius's legion, along with three others, has undertaken a “great march” of 30,000 Roman paces, the equivalent of nearly 36 kilometers.

今天，Servius的军团和其他三个团，进行了3万步（古度单位）的宏大行军仪式，相当于近36千米。

I would not say that. No one would say that. A light year is a unit of distance not time.

我可不会这么说。没人会这么说，光年度单位不时间单位。

36. According to the text, what was the basic unit of length in the UK?

36. 根据本文，英国的基本度单位什么？

In the UK, the yard was considered the base unit of length.

在英国，码被认为基本的度单位。

Now, if we move from the physical world to the theoretical world and talk about the artificial construct of splitting time into different units, for the majority of human history, units of time have had different lengths.

现在，如果我们从物理世界转向理论世界， 讨论将时间分割成不同单位的人为构造，对于人类历史的大部分时间来说， 时间单位的度都不同的。

For the majority of recorded human history, units like the weight of a grain or the length of a hand weren't exact and varied from place to place.

在有记载的大部分人类历史中，像以谷物重量或手掌度为单位的度量方式并不精确， 且各地标准不。

In the Metric System, we have: millimeter: A millimeter is a very small unit of length in the Metric System.

在公制系统中，我们有：毫米：毫米公制系统中个非常小的度单位。

The point (1, 1) sits a distance one away from the origin with an angle of 1 radian.

点(1, 1)距离原点个单位度，角度为1弧度。

And still with unit lengths. You often think of these as the rotation matrices.

还单位度 你通常认为这些旋转矩阵。

The unit length is l. According to the finite difference principle, the finite difference form of Equation (4) is For the boundary conditions of the existing tunnel, it is assumed that both ends of the tunnel are free.

单位度为 l。根据有限差分原理，方程（4）的有限差分形式为：对于现有隧道的边界条件，假设隧道的两端都自由的。

A light-year is a unit of length, with one light-year equaling the distance that light would travel in a vacuum in one year.

光年度单位， 光年等于光 在真空中年的传播距离。

These are the ones which leave all the basis vectors perpendicular to each other with unit lengths.

这些使所有基向量相互垂直且度为单位度的变换。

I just used three examples of length measurements with three different units, inches, feet, and meters.

我刚刚使用了三个不同单位的度测量示例：英寸、英尺和米。
