给定文法及该文法各非终结符所对应的FIRSTVT和LASTVT集，能依据文法和FIRSTVT和LASTVT生成算符优先分析表。

动态模拟算法的基本功能是：

输入一个给定文法，及FIRSTVT和LASTVT集；

输出算符优先分析表生成算法；

输出算法优先分析表构造的过程；

主要是依据构造算符优先关系的算法来绘制优先关系矩阵表。

-Given the grammar and the grammar nonterminals corresponding FIRSTVT and LASTVT set to based on grammar and FIRSTVT and LASTVT generation of operator precedence table. The basic function of the dynamic simulation algorithm is: Enter a given grammar, and FIRSTVT and LASTVT set　output operator precedence analysis table generating algorithm　output algorithm of table construction process priority　main priority is based on the relationship between structure operator algorithm to draw priority relationship matrix.
