1.an international unit of measurement for telephone use, equal to one caller using the telephone for one hour
1.PHP is used for the front-end, Erlang is used for Chat, Java and C++ are also used in several places (and perhaps other languages as well).
PHP用于前端，Erlang用于聊天，Java和C++也用在一些地方（也许还有其他语言）。
2.Functions in Erlang are the basic building blocks of any program, just as with any other language.
与其他语言一样，Erlang中的函数是所有程序的基本组成部分。
3.After a small amount of experimentation I was able to make Erlang talk to a web page using pure asynchronous message passing.
在经过了一些试验以后，我可以让Erlang和一张Web网页通过纯异步消息传输进行通信。
4.Single assignment in this means that if you want to calculate the result of a value you must assign it to a new variable (see Listing 30).
在Erlang中，只能赋值一次意味着：如果希望向计算某个值的结果，则必须将它赋值给新的变量（参见清单30）。
5.Floats in Erlang are used to represent real numbers, and can be expressed naturally, as shown in Listing 7.
在Erlang中，会使用浮点数代表实数，并且可以自然地表达浮点数，参见清单7。
6.In Erlang, you separate these statements using a semicolon, so the basic Fibonacci function can be defined as shown in Listing 2.
在Erlang中，使用分号分隔语句，所以可以用清单2所示的代码定义基本Fibonacci函数。
7.In Erlang the last line of a function is the implied return value (just like Ruby) and it always ends in a period.
在Erlang中，函数的最后一行默认成为函数的返回值（和Ruby一样），并且总是以句号结尾。
8.Writing an application in Erlang involves writing actual modules, not just the expressions shown in the interactive shell.
用Erlang编写应用程序需要编写模块，而不只是编写交互式shell中看到的表达式。
9.Erlang has no shared memory, and in it all state is immutable.
Erlang无共享内存，且其中的所有状态都是不变的。
10.In an object oriented programming language these rules would most likely be modeled by a list of instances; in Erlang we use functions.
在面向对象编程语言里，我们大概会用一组对象实例来给这些规则建模；而在Erlang里，我们用函数。
