In fact, that is, naked oats oats, oat flour or Y plane.
其实莜麦即燕麦,莜面即燕麦粉。
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。
Besides that, we presents the gravitational wave energy density under the weak field situation and gives the x - y plane numerical calculation to curvature scalar R and energy density .
还有计算了在弱场条件近似下引力驻波的能量密度,并给出曲率标量R和能量密度平面的数值计算。
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。
And similarly, actually, if we're looking at our polar coordinates here, what we see is it's any place where theta is equal to is what's going to put up on the x-y plane.
类似的,如果我们,看这里的极坐标系,我们能看到只要在theta等于,多少的地方就是xy平面。
Then, I gave you one other very important example of a particle moving in the x-y plane.
下面我再拿一个重要的例子,质点在 x-y 平面内的运动
