For this reason, the paper put forward a comparable method that transforms all of them to R-X plane.

为此提出了将两者都归算到R - X阻抗圆平面上比较的方法。

Then I will have a little piece of x, y plane that is in here.

那么就有了一个在这里的x，y小平面。

So, let's say that we take still the same line up there, x+2y+4z=7 and let's consider the plane with the equation x+2y+4z = 7.

我们还是看之前的那条直线，同时考虑平面。

The first plane ever to fly faster than the speed of sound was the X-1 in nineteen forty-seven.

Another way to represent a point in a plane is I've got a radius and I've got an angle from the x-axis, right, and that's a standard thing you might do.

平面上面的点的方法,也就是极坐标,上面那种方法其实是，如果你们喜欢我这么说的话,笛卡尔坐标表示法。

So, it's the x-y plane, you can see there's no electron density anywhere there.

它在ｘｙ平面，你们可以看到在这里没有电子密度。
