http://www.google.com/search?sclient=psy&hl=en&newwindow=1&site=&source=hp&q=shopping&btnG=Search#sclient=psy&hl=en&newwindow=1&source=hp&q=%E8%B4%AD%E7%89%A9&aq=f&aqi=&aql=&oq=&gs_rfai=&pbx=1&fp=d5a61cbe48a951c1
then you can see that there are two links in 'Ads' area, but move to your mouse pointer to these links, they are:
http://www.google.com/aclk?sa=L&ai=**CYB017kwHTa7GIsT0rQeqnujiCbmK0tEB2dyc_RqQtLWLAQgAEAEoAlCl7byW______8BYJ250IGQBcgBAakCwbO8-f4qhD6qBBlP0FHICrzLP3Yh2d7vTjWYUE8AvmD9DoLL...

for China search engine baidu it also encodes the ads links, so can anyone know what encode algorithm they use to encode ads link urls? thank you in advance.

It's likely that these values act as tokens, linking to the URL in their back-end instead of being an encoded version of the URL itself - as such it would not be possible to convert these values directly to a URL without querying their servers.
