while upgrade my os x 10.8 to maverick, it ask me to create a new user.
after that, a folder for the new user is created in the /Users, but there is no information for this new user in the System Preferences -> Users & Groups,
i can't event delete this new user in the Users & Groups setting panel.
so how can i delete this new user?
That may be because you are logged into the new user.
In any case, this support article should help...
