For $i = 1 To UBound($sR) - 1 Step 2
        If IsDeclared('_' & $sR[$i]) Then ContinueLoop

        Assign('_' & $sR[$i], 0)
Next
FileWrite('new.txt', $out)

再上一段测试效率的代码，完成不超过1毫秒

Local $Str = _
                '2010-08-04 12:58:31 :AVcc12' & @CRLF & _
                '2010-08-04 12:58:34 :AVcc13' & @CRLF & _
