single bond ˈsiŋɡlbɔnd 短语¹⁴⁴⁹⁷²⁺²
基本例句
单键
And by that what we mean is that they're absolutely identical, and it turns out that this here is not a double bond, it's not a single bond either, it's actually something in between.
这意味着它们是绝对完全相同的，实际情况应该是这不是一个双键，这也不是一个单键，而是介于两者之间的状态。163
And the bond order you get out will either be, for example, zero, which would mean that you have no bond, 5 or you could have1, a single bond,1.
你得到的键序要么是比如说是零，这意味着没有键，或者你会得到1，单键1。163
The specificity of hydrogen ion catalysts, for example, is very broad, whereas many enzymes perform only a single function, such as hydrolysis of a single bond or bond type.
例如，氢离子催化剂的催化范围特性很宽，反之，许多酶执行的只是单一的功能，譬如一种单键或一种键型的水解。 exue
The variation of electronic structure leads to the increase of single bond radius and atomic volume and other changes of physical properties.
电子结构的转变是导致原子单键半径增大和体积增加及其他物理性质发生改变的根本原因。 cnki
And something that we'll see later on is that triple bonds, for example, are going to be stronger than a corresponding double bond or a corresponding single bond.
而我们以后还会看到三键，举例来说，应该更强，相较于相应的双键,或者相应的单键来说。163
And we find the same thing for these two atoms here, it's not actually a double bond, it's somewhere between a single bond and a double bond.
而且我们发现这两个原子的情况是一样的，它其实不是一个双键，而是介于单键与双键之间的。163
Another is the single covalent bond also called a single bond. This is when two atoms share a single pair of electrons.
一种是共价单键，也可称为单键，由两个原子共享一对价电子形成。 suiniyi
During the ozone oxidation process of furnace black, the carbon- oxygen single bond can be formed mainly, but further oxidation to the carbon-oxygen double bond is very difficult.
炉法炭黑表面臭氧化过程中主要生成的是表面碳氧单键结构，进一步氧化为双键的程度很低。 cnki
If we're talking about a single bond, we're talking about2 orbitals overlapping in the internuclear axis.
如果我们讨论的是单键，我们讨论的是两个轨道,在核间轴中重叠。163
Or if we look at how strong it is, it's actually stronger than a single bond, but weaker than a double bond.
或者如果我们看键的强度的话，它实际上比单键更强，而比双键更弱。163
Remember, every time we have two electrons that are being shared, that's a single bond.
还记得，每次我们有两个电子被共用，我们就有了一个单键。163
So if we look at its length, it's actually shorter than a single bond, but longer than a double bond.
因此如果我们看它的键长的话，它实际上比单键更短，却比双键更长。163
The differences in structural type and contents of carbon- oxygen single bond between the contact black and the furnace black are very evident.
研究结果指出，接触法炭黑与氧化炉法炭黑的表面在碳氧键合结构形式及含量上有很大的差异； cnki
When we have just a single bond in them molecule, you have all the free rotation you want, you can just spin it around, there's nothing keeping it in place.
当我们在分子力只有一个单键时，你可以随意旋转，你可以让它转起来，没有什么东西能固定住它。163
Yeah, we'd expect to see a single bond in hydrogen.
嗯，我们预计在氢分子里会看到一个单键。163 |
