每个按键上都有若干字母(比如“2”键上同时有abc三个字母)，只要重复按键就可以选择相应字母，直到选到你要输入的为止。
Multiple letters are assigned to each key (the "2" key is also "ABC", for example), and tapping repeatedly on a key switches between its corresponding letters until the desired character is chosen.
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。
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.
是氢的键更短，还是氮与氮的三键更短？

正常的链接是二硫键，可以被热度和酸度变化所破坏，导致蛋白质失去三维结构。
The normal kind of bonds - disulphide bonds - can be broken by changes in heat and acidity, causing proteins to lose their 3d structure.
注意，上例中的键映射使用了一个包含类似c的“三元表达式”的表达式。
Note that the key-mapping in the previous example USES an expression containing a C-like "ternary expression".
比如，在这下面我写的是氮分子2,而这个是氢分子，但我在上面把这些分子的形式改写了，大家可以看到,这是一个氢与氢之间的单键，含一个氮与氮之间的三键。
So, for example, down here I wrote that it was n 2 and that it was h 2, but when I re-wrote the molecules up here, you saw that it's an h h single bond where it's a nitrogen-nitrogen triple bond.
因此你能看到,反键轨道上有两组，三组成键，得到一组净成键，所以成的是单键。
so you can see that there is going to be two sets in antibonding, three sets in bonding for a net of one, giving us the single bond.
支撑S3框架的三个基本概念是bucket、对象和键。
The three basic concepts underpinning the S3 framework are buckets, objects, and keys.

Twitter users are encouraged to add their username by either clicking a link on the home page or sending a tweet to @wefollow and including a maximum of three tags they would like to be listed under.
钻石中的碳原子同它们的相邻原子形成“三维的”化学键，形成了一个坚固的、金字塔般的重复性晶体结构。
The carbon atoms in a diamond form "3-D" bonds with their neighbors, resulting in a sturdy, pyramidlike, repeating crystalline structure.
按下Cmd和Opt键的同时击这个三角形符号，可以折叠或展开所有层级的群组文件夹。
Hold down Cmd + Opt + click on the triangle icon will collapse or expand all level layer groups.
提供了三种不同的组合键进行屏幕截图。
这里三角形是因为,我们有3个原子核中心原子成键，如果你画它，它就是金字塔形的。
So it's trigonal because we have these three atoms that are bound to the central atom here, and if you picture it, it's actually shaped like a pyramid.
一个三键，同样的也有沿着核间轴sigma键。
A triple bond, again is going to have one sigma bond on the internuclear axis.
一旦在三个点的Python提示后按enter键，Python解释器就处于无限循环的混乱中。
Once you press Enter following the last three-dot Python prompt, the Python interpreter starts churning away in an infinite loop.
用户可以一键提交那些没有被提交至digg的文章。此外，digg很快还将使用第三方登录系统，允许Google、Twitter和雅虎等用户直接登录。
Digg will also soon use third-party sign-on systems, including Google, Twitter Connect and Yahoo to allow its users to sign in.
让我们想想怎么来分类单键双键,和三键，这在我们在考虑sigma键,和π键是很有用的。
So let's think about how we can classify single and double and triple bonds, which is what we're really used to dealing with in terms of these sigma bonds and these pi bonds.
第三，编写KeyManger类来维护每个已注册表的代理键。
Third, write the KeyManger class to maintain the surrogate keys for each registered table. The KeyManager class will provide two methods.

How about the Mitsubishi press, which took 300 copies to reach ok sheet, then how many times of ink key need to adjust in between these 300 impressions.
因此，如果我们讨论的是氮与氮之间的单键，双键与三键，那么三键应该是其中最短的一个，同时也是最强的一个。
So, if we talked about a nitrogen-nitrogen single versus double versus triple bond, the triple bond will be the shortest and it will be the strongest.
