标准范围

ISO 639的这一部分提供了一种由语言代码元素组成的代码，其中包含两个字母的语言标识符，用于表示语言名称。ISO 639本部分规定的语言标识符最初设计用于术语、词典编纂和语言学，但可用于任何需要以两个字母编码形式表达语言的应用，尤其是在计算机系统中。alpha-2代码是为世界上大多数主要语言的实际使用而设计的，这些语言不仅在全世界的文献中最常见，而且还包括大量的专门语言和术语。当明显存在大量用专门语言和术语编写的文档时，会创建额外的语言标识符。本代码中不包括专门为机器使用而设计的语言，如计算机编程语言。

This part of ISO 639 provides a code consisting of language code elements comprising two-letter language identifiers for the representation of names of languages. The language identifiers according to this part of ISO 639 were devised originally for use in terminology, lexicography and linguistics, but may be adopted for any application requiring the expression of language in two-letter coded form, especially in computerized systems. The alpha-2 code was devised for practical use for most of the major languages of the world that are not only most frequently represented in the total body of the world's literature, but which also comprise a considerable volume of specialized languages and terminologies. Additional language identifiers are created when it becomes apparent that a significant body of documentation written in specialized languages and terminologies exists. Languages designed exclusively for machine use, such as computer-programming languages, are not included in this code.
