var texts='新闻系统图片新闻栏目'

document.write('<object classid="clsid:d27cdb6e-ae6d-11cf-96b8-444553540000" codebase="http://fpdownload.macromedia.com/pub/shockwave/cabs/flash/swflash.cab#version=6,0,0,0" width="'+ focus_width +'" height="'+ swf_height +'">');
document.write('<param name="allowScriptAccess" value="sameDomain"><param name="movie" value="../Web/images/playswf.swf"><param name=wmode value=transparent><param name="quality" value="high">');
document.write('<param name="menu" value="false"><param name=wmode value="opaque">');
document.write('<param name="FlashVars" value="pics='+pics+'&links='+links+'&texts='+texts+'&borderwidth='+focus_width+'&borderheight='+focus_height+'&textheight='+text_height+'">');
document.write('<embed src="../Web/images/playswf.swf" wmode="opaque" FlashVars="pics='+pics+'&links='+links+'&texts='+texts+'&borderwidth='+focus_width+'&borderheight='+focus_height+'&textheight='+text_height+'" menu="false" bgcolor="#DADADA" quality="high" width="'+ focus_width +'" height="'+ swf_height +'" allowScriptAccess="sameDomain" type="application/x-shockwave-flash" pluginspage="http://www.macromedia.com/go/getflashplayer" />');
document.write('</object>');

谁给我解释下这段JS，特别要解释定义的变量以及document.write（<object></object>）做什么用

var a="njlyzh";
document.write('my name is '+a);

如不清楚，请楼下详解。。。
