On one axis you have dietary fat, the other you have how much-- in fact I should have brought the graph but I didn't-- how much breast cancer there is in the society.
其中一个轴是膳食脂肪摄入量,另一个轴是,事实上我应该把图表带来的但没有,社会上的乳腺癌病例数量
All right, so in terms of s p 3 hybrid orbitals, let's combine all four together on one axis, because this is what's going to happen in an s p 3 carbon atom.
对于sp3杂化轨道,让我们把4个结合起来,因为这是sp3碳原子中发生的情况。
But once in awhile, one of these plus twos comes in almost on axis, and it gets whipped around by the Coulombic repulsive forces.
但是偶尔一个带两个正电荷的粒子,以接近于轴的位置进入,会快速的移动到周围,由于库仑斥力的作用。
I want to put down on this axis the return on the stock market and on this axis I want to put the return on one company, let's say Microsoft.
我把这个轴作为股票市场的收益,这个轴作为某个公司的收益,比如说微软
We said, "Let's take, for the simplest case that we can possibly imagine, namely a particle moving in one dimension along the x-axis with a constant acceleration a.
我们说过,"考虑我们可以想象的最简单的情况,即质点在一维空间运动,沿着 x 轴且保持恒定加速度 a
A triple bond, again is going to have one sigma bond on the internuclear axis.
一个三键,同样的也有沿着核间轴sigma键。
Let's say it's one year and I'm going to actually plot on this axis a person's income this year.
我们假设是一年,我用x轴表示,一个人今年的收入
There's not two bonds, that's one pi bond, and the reason is because it's 2 p orbitals coming together, and remember p orbitals have electron density above and below the axis, so when they come together, it kind of looks like one bonds, but essentially what we have here is one pi bond.
这不是两个键,这是一个π键,因为这是两个2p轨道组合而成的,记住p轨道在键轴之上,和键轴之下都有电子密度,当它们靠近时,这看着很像两个键,但本质上它是一个π键。
