Sorry I come up with this bug again.
I found that i can't reply to my previous bug report.

I have the following function added to after-frame-created-functions.
(defun my:set-frame-size (&optional frame)
  (interactive)
  (unless frame
    (setq (selected-frame) frame))
  (if (display-graphic-p)
      (progn
    (tool-bar-mode -1)
    (message "set frame size")

    ;; This should be an emacs bug.
    ;; i have to add a fake operation on frame here.
    ;; (set-frame-height frame 29)

    ;; for the height, subtract a couple hundred pixels
    ;; from the screen height (for panels, menubars and
    ;; whatnot), then divide by the height of a char to
    ;; get the height we want
    (set-frame-height frame
              (/ (- (x-display-pixel-height) 200)
                 (frame-char-height)))
    ;; use 120 char wide window for largeish displays
    ;; and smaller 80 column windows for smaller displays
    ;; pick whatever numbers make sense for you
    (if (> (x-display-pixel-width) 1280)
        (set-frame-width frame 120)
      (set-frame-width frame 80))
    )))
(add-hook after-frame-created-functions my:set-frame-size)

I have serveral experiments.

1. If i use the code shown before, after 'emacsclient -c -a ""', every
emacsclient frame can set width corrently and its height stay unchanged.

2. If i move the part of set width code before set height code, height can
be changed correctly while width can't.

3. If i add a fake (set-frame-height(or width) whatever), like that
commented by me, I can set both height and width.
