how to combining "maxima-mode" and "imaxima"

You need to set this flag to t, then start imaxima. This will create
buffer named *maxima* with a maxima process plus running imaxima.

If you want to have a maxima-mode function automatically open an imaxima
inferior process, then you can use the defadvice facility:

(defadvice maxima-send-region (before maxima-start-imaxima first)
   "Ensures that imaxima is running and the correct flag is set."
  (setq imaxima-use-maxima-mode-flag t)
  (imaxima))
(ad-activate 'maxima-send-region)

I advise maxima-send-region because all the *-send-* functions are  
specialisations of it.
