语义信息编码是一项复杂的综合集成工程，我们称之为“通用语义码建模工程”。

Semantic information coding is a complex synthetic and integrative engineering, which we intitule as "modeling engineering of universal semantic codes".

比如，return、break和this在某一代码块中的语义与其在Runnable(或其他内部类实例)中同一代码块中的语义是不同的。

For example, the semantics of return, break, and this are different in a block of code than they are in a Runnable (or other inner class instance) that represents the same block of code.

从语篇结构角度分析，语码转换可用以充当句子结构成分，赋予语义上的强调和形式上的对比。

If it is viewed from the discourse analysis, code-switching serves as constituents emphasizing meanings and forming structural contrasts.
