Translation of "Breadth" in Chinese

I missed the train by a hair's breadth.

我以一分之差错过了那趟火车。

That Space, as our mathematicians have it, is spoken of as having three dimensions, which one may call Length, Breadth, and Thickness, and is always definable by reference to three planes, each at right angles to the others.

正如我们的数学家所言，这个空间有三个维度，可称之为长度，宽度和厚度，并且始终可以通过参考三个平面来定义，每个平面彼此成直角。
