The hidden-layer R of RBF neural network consists of a set of RBF (radial base function).

径向基函数（RBF）神经网络隐含层R由一组径向基函数构成。

We also obtain the variation of the radial dispersion of velocities with r through the stability of the density wave in three-dimensional dishlike galaxies.

同时，从三维盘状星系密度波的稳定性讨论推出了径向速度弥散度的变化规律。

The radial axis (R-R) traverses a radial line (x) that radially extends from a common axis of rotation (A-A) of the tire (12) and the wheel (14).

所述径向轴(R - R)横过从所述轮胎(12)和车轮(14)的共同的旋转轴(A - A)上径向伸出的径向线(X)。

We will always have r equals zero in these radial probability distribution graphs, and we can think about why that is.

在这些径向概率分布图里,总有ｒ等于０处，我们可以考虑为什么会这样。

So, you remember from last time radial nodes are values of r at which the wave function and wave function squared are zero, so the difference is now we're just talking about the angular part of the wave function.

你们记得上次说径向节点在,波函数和波函数的平方,等于零的ｒ的处，现在的区别是我们讨论的是,角向波函数。

We'll introduce in the next course angular nodes, but today we're just going to be talking about radial nodes, psi and a radial node is a value for r at which psi, and therefore, 0 also the probability psi squared is going to be equal to zero.

将会介绍角节点,但我们今天讲的是，径向节点，径向节点就是指，对于某个r的值,当然，也包括psi的平方，等于,当我们说到s轨道时。
