双语例句
- Free radical is a group of one or more than one unpaired electrons stayed high energy excited state which molecule induced by physical or chemical factors produce.
自由基是由于分子在物理或化学因素作用下产生含有一个或一个以上的不配对电子,处于一种不稳定的高能激发态。 - A free radical is a molecular fragment having an unpaired electron.
自由基是一种具有未配对电子的分子碎体。 - So now what we have is four unpaired electrons.
现在我们有4个未配对电子。 - And I cannot have an unpaired electron in the same orbital.
我不可能在同一个轨道,得到不成对电子。 - These unpaired electrons are the cause for the high chemical reactivity of free radicals.
由于这些不配对电子,这些分子或原子常具有高度的化学活性。 - So we can bring in four hydrogen atoms, which will each contribute another unpaired electron.
我们可以引入4个氢原子,每个贡献一个未配对的电子。 - So, using our simple valence bond theory, what we would expect is that we want to pair up any unpaired electrons in methane with unpaired electrons from hydrogen and form bonds.
利用简单的价电子成键理论,我们预计,要把所有甲烷中没有配对的电子,和氢原子中没有配对的电子配对来形成键。 - S& we don't have to hybridize it, it already has only one unpaired electron in a1 s orbital.
s-我们不用杂化它,它已经有而且仅有一个未配对电子在s轨道里。 - You can see that we have two unpaired electrons in this molecule here one in the pi2 p x star, and one in the pi2 p y star orbital.
你们可以看到我们这个,分子力有两个未配对电子,一个在π2px星,一个在π2py星轨道。 - And what I want to point out that we just figured out for molecular orbital theory, is that o2 is a biradical, because remember, the definition of a radical is when we have an unpaired electron.
我要指出的是,我们刚利用分子轨道理论,指导了O2是二价自由基,因为记住,自由基的定义是,有个未配对的电子。
