改这里就可。
window.onload=function(){ 
var o=document.getElementById('infozone');hscroll(o); 
var interval = window.setInterval(function(){window.clearTimeout(tc);o.firstChild.style.marginLeft='0px';scrollup(o,20,0);},2000); 
o.onmouseover= function()
{
    window.clearTimeout(interval);
}
o.onmouseout  = function()
{
interval = window.setInterval(function(){window.clearTimeout(tc);o.firstChild.style.marginLeft='0px';scrollup(o,20,0);},2000); 
}}
