How does Perl manage memory? Does an object be automatically released, if it is only refered as a local variable within a block?

Yes, it's released, but not given back to the operating system. Which means that the memory can be used for other Perl variables, but not from other processes.

Another question: In loop conditions, after each time of run, does the memory of local variables -- which are inited within the loop BODY(not the heading of loop) -- being deleted and released, and recreated next time?

Yes. (Although there's an optimization which takes care that only the contents of the variable are deleted, not the variable itself).
