查找：

    <div id="announcementbody"><ul>$announcements</ul></div>

替换成：

    <div id="announcementbody"><marquee scrollamount=4 onmouseover=this.stop() onmouseout=this.start()><ul>$announcements</ul></marquee></div>

<div id="ann" onmouseover="annstop = 1" onmouseout="annstop = 0">

    <dl>

      <dt>{lang announcements}:</dt>

      <dd>

        <div id="annbody"><ul id="annbodylis">$announcements</ul></div>

      </dd>

    </dl>

  </div>

1.首先在templates/default/ 目录下找到discuz.htm这个网页文件
2.查找<div id="announcementbody"><ul>$announcements</ul></div>
3.修改成 <div id="announcementbody"><marquee onmouseover=this.stop()  scrollAmount=4><ul>$announcements</ul></marquee></div>
4.说明：scrollAmount=4可以设置数值改变移动速度，数字越大越快
