I knew many them for single wp can be used for wpmu without any changes, but some themes are not, is there some standards to verify it? is there any special requirments for mu? thanks!

You can also check out the Theme Compatibility information on the WIKI: http://codex.wordpress.org/WPMU_Theme_Compatibility
There is no special requirements. *Most* themes work, the only exceptions I have seen are ones with options pages created with Ohz's Theme Toolkit. THey give the White Screen of Death, but can be fixed.
Seconding andrea_r: I've got roughly 100 themes installed, just 'normal' WordPress themes. All but maybe 2 have worked, and the 2 that didn't work seem to require plugins that I don't care to install, as opposed to WPmu problems.
Best thing to do is test it yourself on a test site. You can probably also search the forums here for specifics ones to see if anyone has had any problems previously.
Thank you, all of you, happy new year!
