双语例句
- Electron spin resonance technique ( ESR) is a type of magnetic resonance. It can be used to study on asymmetric electron system. An unpaired electron system also can be studied with self-rotate marking method for ESR technique.
电子自旋共振（ElectronSpinResonance，简称ESR）技术是磁共振技术的一种，它可以对不成对的电子体系进行研究，而且对于不成对电子体系，可以采用自旋标记技术进行ESR的研究。 - 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。 - 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。 - 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。 - H2 So the simplest case we can think of is with h2 where we have two unpaired electrons, each in a1 s orbital of a separate h atom.
最容易想到的例子是2，我们有两个未配对电子，每个都在一个分开的1s轨道上。 - 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。 - 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 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。 - The free radical theory of aging posits that substances with unpaired electrons attack the body's molecules and cause the functional decline of organs over time.
衰老的自由基学说指出，自由基中的不配对电子攻击人体内其他物质的分子，从而进行配对，引起器官功能衰退。 - 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。
