$(function () {
  var _speed = 1000;
  var _len = 0;
  var _size = 150;
  var _direction = 'left';
  function mar(){
    if(_direction == 'left'){
      if(_len >= 450){
       _direction = 'right';
      }else{
       $(".flow ul").animate({"margin-left":"-=" + _size + "px"});
       _len += _size;
      }
    }else{
      if(_len <= 0){
       _direction = 'left';
      }else{
       $(".flow ul").animate({"margin-left":"+=" + _size + "px"});
       _len -= _size;
      }
    }
  }
  var _go = setInterval(mar,_speed);
  $("#pic_left").click(function (){
   _direction = 'left';
  });
  $("#pic_right").click(function (){
   _direction = 'right';
  });
  $(".flow li").mouseover(function (){
    clearInterval(_go);
  }).mouseout(function (){
    _go = setInterval(mar,_speed);
  });
});
