Is /var a separate filesystem on your system?  /var is used for temporary files which may account for the difference depending on the type of temporary files that are being created and when they are created/removed.  Try restarting the system and issuing the two commands again if /var is a separate filesystem and provide the output from these two commands for us.

yes, /var is a separate fs about 260MB,i've changed the log
file to other partition which used /var/log before,(because
it's too small to record huge logs),but /var/spool/mqueue &
/var/spool/mail need some spaces,it seems that i'd better n
ot to change SENDMAIL's options,right?
 I can NOT restart my server now,because of 7/24 using,so i
just want to know if i use the command i wrote above,it sho
ule tell me all feature of /var space using,is that right?

You never did show us the output from your commands.  It is hard to give you an answer with the information you provided.  In general, disk space from files that are deleted should show immediately unless there is something else going on but you resolved the problem before we could analyze.  Has this happened again?  In any case, you should problably close this one.
