polar coordinate
基本解释
- 極坐標；極座標；極坐標系統
英汉例句
- This guy, you have two different ways of getting its polar coordinate equation.
有兩種辦法,可以得出極坐標系下的方程。 - Say, polar coordinates. Let's say that I have a function but is defined in terms of the polar coordinate variables on theta.
比如說極坐標，有一個函數,是根據極坐標θ定義的。 - And because you integrate first over r, well, first of all you should remember the polar coordinate formulas, namely x equals r cosine theta and y equals r sine theta.
這樣的話，我們就先對r積分，儅然了，首先得要記住坐標轉換的公式，也就是x=rcosθ，y=rsinθ

专业释义
- 極坐標
The polar coordinate and Fast Fourier Transform(FFT) method are introduced to determine the invariant features of the transformed matrix. The targets are classified and recognized by calculating the same correlation of the characteristic matrix and the template features matrix.
