wget的bad request问题

scopio

当我试图用wget 下载sciencedirect上面的文献时，提示 400 Bad Request，可是同样的文献我可以用windows下面的flashget下载

1. 
   
2. $ wget --proxy=off "http://www.sciencedirect.com/science?_ob=MImg&_imagekey=B6X10-4FXHH70-1-1&_cdi=7228&_user=10&_orig=search&_coverDate=04%2F22%2F2005&_sk=999999999&view=c&wchp=dGLbVzz-zSkzS&md5=55a570fde495514af4cf6c72d5374dbc&ie=/sdarticle.pdf" -O a.pdf

请问如何才能把这种地址下载下来呢？

我发现curl也可以正确下载，可是为什么wget不行呢？
