双语例句
- All unpaired atom, molecule and atomic group are called free radicals, which exist in body widely.
凡是具有未成对电子的原子、分子或原子团都称为自由基，在体内分布广泛。 - Free radicals develop when atoms in the body's cells have unpaired electrons, which can lead to damage to different parts of the cell, including DNA.
自由基发生是当身体细胞中的原子有单电子，能导致包括DNA在内的细胞不同部分的破坏。 - So now what we have is four unpaired electrons.
现在我们有4个未配对电子。 - But what we see we have is that we only have two unpaired electrons here.
但我们看到，我们只有两个未配对的电子。 - 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。 - There are B-H bond, H-H bond and atom-molecular bond in BH+ 4 and BH4. There are four equivalent B-H bonds in BH-4. In the case of BH4 there is an unpaired electron that occurs near the boron atom.
BH4+和BH4中都存在BH键、HH键和原子-分子键；而BH4-中存在着四个相同的BH键； - At the end of the day you have some unpaired electrons.
今天的最后，你有些未成对电子。 - Three unpaired electrons in nitrogen.
有三个未成键电子在氮原子中。 - 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。 - On the other hand, the double helix DNA molecule with low symmetry has a lot of hanging bonds, and the unpaired electrons of these hanging bonds may come into the π-electrons system.
另一方面DNA分子具有双螺旋结构，其对称性较低，分子中存在大量的悬挂键，这些悬挂键上的未成对电子也会进入π&电子系统。
