展开后的太阳能电池板面与探测器轨道轴成30度俯角。

After deployment, the solar panel plane is canted by 30? To the spacecraft pitch axis.

随着地球围绕太阳的轨道和轴的倾斜将我们带到这个半球，我们更远离直接接收太阳光线的地方。

Earth's orbit around the sun and tilt on its axis combine to carry us in this hemisphere further away from receiving the sun's rays most directly.

轨道是沿着键轴,有节面的分子轨道。

Pi orbitals are a molecular orbital that have a nodal plane through the bond axis.

So even though we see a nodal plane down the center, I just want to really point out that it's only when we have a nodal plane in the internuclear or the bond axis that we're calling that a pi orbital.

虽然在中间有个节面，我想要指出的是,只有节面在核间轴,或者键轴上时,我们才叫它π轨道。

If we're talking about a single bond, we're talking about 2 orbitals overlapping in the internuclear axis.

如果我们讨论的是单键，我们讨论的是两个轨道,在核间轴中重叠。

And a sigma bond forms any time you have two orbitals coming together and interacting on that internuclear axis.

当你把两个轨道合在一起,并在核间轴上有相互作用时,就形成了sigma键。
