根据GBK编码反查拼音，先根据拼音与文字对应关系生成自定义码表，再根据码表反查拼音，如果对码表大小有要求，可以修改码表算法，如果对反查速度有要求，可以使用当前算法。

反查速度要求：通常在0.00061秒

码表大小要求：通常在0.0162秒(查询算法有待改进)-According to GBK encoding anti-check spelling, the first based on correspondence between spelling and writing custom code to generate the table, according to counter-check the spelling code table if the table size requiried, you can modify the code table algorithm, if the search for anti-speed required, You can use the current algorithm. Reverse speed requirements: usually in 0.00061 seconds chronograph Size Requirements: typically in 0.0162 seconds (query algorithm needs to be improved)
