Traditionally,Yacc and Lex is a pair of tools to be used to facilitate writing compilers.In its non-compiler oriented applications as described in this paper,they are used to implement the translation between a program′s runtime internal data structure adn a static external store in a disk file form to catch the internal data structure.

传统上，Yacc和Lex是作为一对用来帮助实现编译器的工具，本文描述了二者在非面向编译器的应用中，它们是如何被用来实现把一个程序运行环境中的内部数据结构和以一个磁盘文件的形式出现的用来保存内部数据结构的静态外中存储之间的相互转换。

The selection of fracture splitting forceparameter mainly depends on experience and no theory can abide by.In this paper aim at the technique of fracture splitting of engine connectingrod, the materials fitting to fracture splitting have been analysed, according tosome influence factors that the former has researched. The influence that thechemistry compositions to the mechanics function and the physical function insteel have been analyzed. The theory of quasistatic fracture splitting of suitableconnecting rod for engine EA827 has been studied. Aimed at the new materialC70S6, the quasistatic procedure has been numerical simulation analyzed bySPH non-mesh method. The solved stress intensity factor module andparameterize model building module have been developed based ANSYS byAPDL.
