//获取一个串的汉字的个数
Var
i: integer;
CurrentChar: char;
CurrentStr: String;
Begin
Result := 0;
If Length(Str) = 0 Then Exit;
For i := 1 To Length(Str) Do
Begin
CurrentStr := Copy(Str, i, 1);
CurrentChar := CurrentStr[1];
If Ord(CurrentChar) >= 127 Then Result := Result + 1;
End;
Result := Result Div 2;
End;
