PHP Namespace >>> new namespace\Class ??????

[lvfujun]

各位大牛
\home\a.php
a.php: content<<<start
namespace aa;


class bb{
public function index(){
}
}
End;



include /home/a.php
content<<<start

include '/home/a.php'

$class = new \aa\bb;
$class->index():


End;


Error:<<<
Fatal error: Class 'aa\Filters' not found i
>>>

求大牛看看问题所在.为什么不能new 命名空间的class！感谢！
