根据这种观点，多层介质波导中波的传播和散射可以归结为多维空间向量的坐标变换，并可用传输线和网络表示。

According to this point of view the transmission and scattering in multilayer dielectric waveguides can be regarded as coordinate transformation of a vector in ann-dimensional vector space.

不管那些了，我断言我们可以找出移动点的位置了,因为对于向量1,我们可以找出Q0和Q1的坐标。

So, OK, so apart from that, I claim now we can find the position of its moving point Q0Q1 because, well, this vector, Q0Q1 we can find from the coordinates of Q0 and Q1.

我来举个例子，解释为什么我们用向量来学习参数曲线，毕竟我们学了这么多的都只能在坐标上完成。

OK, so let me show you a nice example of why we might want to use vectors to study parametric curves because, after all, a lot of what's here you can just do in coordinates.
