    <head>
    <meta http-equiv="Content-Type" content="text/html; charset=gb2312">
    <meta name="GENERATOR" content="Microsoft FrontPage 4.0">
    <meta name="ProgId" content="FrontPage.Editor.Document">
    <title>New Page 1</title>
    <script language='javascript'>
    function TestBrowser()
    {
      ie=((navigator.appName== "Microsoft Internet Explorer")&&(parseInt(navigator.appVersion)>=5.5));
      if(ie)
      {
        document.all.T1.style.visibility="visible";
       }
     }
    </script>
    </head>

    <p><input type="button" value="打印" name="T1" style="visibility:hidden"></p>
