The ordered swirl of houses and streets from this high angle sprang at her now with the same unexpected, astonishing clarity as the circuit card had.
从这个高的视角,看到的像漩涡一般,排列有序的房屋和街道,就像当初的印刷电路一样,以未曾预料的,令人惊讶的清晰感。
But because there's this lone pair here, it's pushing down on the other bonds, 5° so we end up with an angle of less than 109 . 5 degrees.
但因为这里有孤对,它会把其它键向下压,所以键角会小于109。
You can imagine that if a vector is viewed from an angle, then its components will vary with the perspective.
你可以想象一下,如果换一个角度观察矢量,其分量会相应地发生变化
And just to give you a sense, if you do a cross-cut of this, you cannot show it from this angle, but it should really be sort of a dumbbell shape with the nodal plane in between the two nuclei.
告诉你们这些就是给你们点概念,假如你们把他横切切开,不能从角度上展示,但它还是会保留几分哑铃的形态,以及在两核之间的节面。
Okay. For those who have not seen a radian, it's just another way to measure angle with the understanding that a full circle, which we used to think is 360 degrees, So a radian is roughly 60 degrees.
我想告诉那些还不懂弧度制的同学,这是衡量角度的另一种方法,理解起来是这样的,对于一个整圆,也就是我们之前所说的360°,所以1弧度大约是60°
