说明： Delphi写的表达式计算演示，相当好的一个基础学习示例，感谢原作者的分享。
(Delphi the expression evaluates demo write, quite good an example based learning, thanks to the sharing of the original author.)

G'=({S,E},{+,-,*,/,^,'(',')',i},P,S)
P:如下
S:E {acc,放值到Result中}
E:E+E {取两个值，计算}
|E-E {取两个值，计算}
|E*E {取两个值，计算}
|E/E {取两个值，计算}
|E^E {取两个值，计算}
|'('E')' {什么也不作}
|i {推i到栈中}
产生式：
(1)S:*E
(2)S:E*
(3)E:*E+E
(4)E:E*+E
......
(27)E:*i
(28)E:i*
