1. Some movements involving primarily vertical or horizontal motions of the body as a whole, in which rotations can be ignored, can be studied using simple equations of linear motion in three dimensions. 有些运动主要涉及整体的垂直或水平运动，其中转动可以忽略，可以用三维线性运动的简单方程来研究。
2. With three dimensions, you can see why it is called a cube. 使用三个维度，您就会明白为什么要将其称为多维数据集。
3. So far, we have represented three dimensions of information explicitly. 到目前为止，我们已经显式地表示了信息的三维。
4. But you can re-fuel in three dimensions which is another interesting challenge. 但是，你们可以再填上燃料到3个部分去，那是个很有趣的挑战。
5. It helps that natural history looks good in high-definition and in three dimensions. 这有助于博物学在高清晰度和三方面看起来不错。
