 And I will also introduce a language I designed
 to practice this computation model.
 
-My language's main contribution to interaction nets,
-is to use stack and postfix notation to build nets.

-What is stack? What is postfix notation? How to build nets?

 在这篇文章中，我顺着拉丰的论文中的例子，来讲解反应网的原理，
 并且介绍我设计的，用来实践这个计算模型的程序语言。
 
-我的语言对于反应网的主要贡献是，
-用栈和后缀表达式来构造网。
-
-何为栈？何为后缀表达式？如何构造网？

-细读下文，自有分解。
