Thanks, Seth and Kasper. The advice helped me. I already fixed this problem
and install bioconductor successfully.:)

According to reading:
1, (?download.file) in R to show how to change 2 environment
variables:http_proxy, http_proxy_user
2, related questions and answers in R maillist and [bioc] to find there
might be two ways to fix the problem:
by starting R with option--internet2, or by changing environment variables
3, I also got help from Kirstine who asked the similar question weeks ago
which was solved by starting R with option. Elmar send me some dos batch
code on it. Since I also need to tell R my user name and password, it worked
but not total fixed. Elmar may know more on it.  I believe somebody should
know the final answer by this method.

I finally solve it by changing environment variables. I use WinodwXP.I found
teh environment variable information on google search.  It might be simple
but I am thinking someone else may some day have the same question as me and
he won't need spend much time solving it if I write in very details. So be
patient:)

1, right click "my computer"-->"properties"--> "advanced"-->"environment
variables"
2, in "system variables" of this panel, click "new"
3, name " http_proxy", value " http://proxy.dom.com:8080/"; (how to set the
value , please read  ?download.file)
4, click"new again",name " http_proxy_user ", value "user:password";
(optinal, if you have these)
5,click  OK to finish

6 ,restart compter (there are some message about WMI showed)
7, open R
8, put in R
 source("http://www.bioconductor.org/biocLite.R")
biocLite()

Here bioconductor was installed successfully. I reatsrted computer to make
sure, everything looks fine, WMI message did not appear again.

Well, not sure if it is a very correct and good way to solve the problem.
But it solved. :)

Welcome to adjust and add advise on this note.

Thanks,
Di
