Dear Yanhua,
I have a link which will help you finding the definition/explanation of all these objects.
http://en.wikipedia.org/wiki/Surface
Type in the keywords in the search field and you should be able to find all the information. Also you can refer to our Help files.
The serial number you have sent is not matching with our database. Could you please let us know your correct SW serial number for our records?
Regards,
Pabitra
