So, if I kind of circle where the probability gets somewhat substantial here, you can see we're much closer to the nucleus at the s orbital than we are for the p, then when we are for the d.

我把概率,很大的地方圈出来，你们可以看到在s轨道上,比p轨道更接近原子核，最远是d轨道。

An image combining orbital imagery with 3-d modeling shows flows of what scientists believe to be water that appear in spring and summer on a slope inside the Newton crater on Mars.

一个结合了3 - D轨道成像技术的图像展示出了科学家们推测的在春季和夏季火星牛顿陨石坑的陡坡上有水的出现。

Objective: to build 3-d digital face model of unilateral orbital defect and find a new method to get 3-d data of facial defects.

目的：建立活体单侧眼眶部缺损的面部三维数字化模型，探讨颜面部缺损三维数据快速精确采集的新方法。

So, it turns out that we have zero nodes that we're dealing with when we're talking about a 3 d orbital.

所以结果是,３ｄ轨道没有节点。

So, the size still for an s orbital is larger than for a d orbital, but what we say is that an s electron can actually penetrate closer to the nucleus.

轨道的尺寸比,ｐ轨道还是要大，但我们说的是ｓ轨道可以,穿透到更接近原子核的地方。

So, I'm asking very specifically about radial nodes here, how many radial nodes does a hydrogen atom 3 d orbital have?

我问的是径向节点，这里3d轨道的径向节点有多少个？
