solved.

check file modified or not use &modified
check window numbers of buffer
I write a function.
function GetWindowCount(expr)
let cur_buf_id=bufnr(a:expr)
let cur_buf_cnt=0
let i=1
while 1
let buf_id=winbufnr(i)
if buf_id==cur_buf_id
let cur_buf_cnt=cur_buf_cnt+1
endif
if buf_id==-1
break
end
let i=i+1
endwhile
return cur_buf_cnt
endfunction
