The content of trace elements didn't affect the apparent metabolism of energy of this phase (P>0.05).

此阶段能量的表观代谢率不受微量元素添加水平的影响（P>0.05）。

When we talk about p orbitals the phase of the orbital becomes important once we talk about bonding, which hopefully you were happy to hear at the beginning of class we will get to soon.

对于ｐ轨道,当我们讨论到成键时，轨道的相位就变得非常重要了,这个我们马上就要讲到了。

And in terms of thinking about the phase of this p orbital, the phase is going to be positive anywhere where z is positive.

对于ｐ轨道的相位，在ｚ大于零的地方都是正的。

So I changed the colors here to show that these are 2 p orbitals with an opposite phase or an opposite sign.

我这里换了一种颜色,表示2p轨道,不同的相位或者是正负号。

And, before leaving P-AWS: In low-speed maneuvering, the system turns the rear wheels out of phase which is to say, in the opposite direction from the front wheels.
