给段源码你参考一下:
function UChineseMN(sr: String): String;
var
C1, Len1, C2: Integer;
ir : Word;
FResult : String;
begin

C1 := 1;
Len1 := Length(sr);
while (C1<=Len1) do
begin
if (ord(sr[C1])>=160) and (ord(sr[C1+1])>=160) then
begin
ir := (ord(sr[C1])-160)*100 + ord(sr[C1+1])-160;
C2 := 0;
while (C2<=26) do
begin
if (ir>=ChinaCode[C2,0]) and (ir<=ChinaCode[C2,1]) then
begin
FResult := FResult+chr(C2+ord('a'));
break;
end;
C2 := C2 + 1;
end;
C1 := C1 + 2;
end
else if ( ( ord(sr[C1]) >=65 ) and ( ord(sr[C1]) <91 )
or ( ord(sr[C1] ) >=97 ) and ( ord(sr[C1]) <123 )
or ( ord(sr[C1]) >=48 ) and (ord(sr[C1]) <58) ) then
begin
FResult := FResult+sr[C1];
C1 := C1 + 1;
end
else
C1 := C1 + 2;
end;
Result := FResult;
end;
