拼音输入法杳询函数: unsigned char code * py_ime(unsigned char input_py_val[]);
input_py_val为已输入的拼音码字符串头指针，
反回值为中文的起始地址，当为0时，杳询失败
应用举例：
{
　　unsigned char input_string[]={"bang"};
　　unsigned char chines_string[100];
　　sprintf(chines_string,"%s",py_ime(input_string));
}(Pinyin input method query function: unsigned char code * py_ime (unsigned char input_py_val[]);
Input_py_val is an input pinyin code string head pointer,
The starting address of the return value is Chinese, when is 0, the query failed
Application examples:
{
Unsigned char input_string[]={"bang"};
Unsigned char chines_string[100];
Sprintf (chines_string, "%s", py_ime (input_string));
})
