程序很大  不好多贴出来 大概流程如下。。。 
vv是定义了一个动态数组。。。如下。其中的数据都合理的定义了   不是数据定义的问题
subroutine CONV_YITA()

    integer*4::i,j
...
    real*8,allocatable,dimension(:,:)::vv

...
call conv_schemes_po(i,jbeg+3,jend-3,methody(1,1))
...
return
contains
        subroutine conv_schemes_po(i1,jbeg1,jend1,flag1)
        implicit none

        integer*4::jbeg1,jend1,flag1,i1
        integer*4::m,kk,slbeg,slend,j1
        real*8,dimension(1:4)::alpha

        if(flag1.eq.301)then
            slbeg=-2; slend=2
        elseif(flag1.eq.303)then
            slbeg=-3; slend=3
        elseif(flag1.eq.305)then
            slbeg=-4; slend=4
        elseif(flag1.eq.411)then
            slbeg=-1; slend=2
        elseif(flag1.eq.413)then
            slbeg=0; slend=2
        elseif(flag1.eq.415)then
            slbeg=-2; slend=0
        elseif(flag1.eq.417)then
            slbeg=-2; slend=1
        elseif(flag1.eq.-1)then
            return
        endif
        print*,"before",i1,jbeg1,jend1,flag1,slbeg,slend
        allocate(vv(1:4,slbeg:slend))
        print*,"after",i1,jbeg1,jend1,flag1,slbeg,slend
...
    deallocate(vv)

        return
        endsubroutine
endsubroutine CONV_YITA

结果却是第一行打印可以打出结果  第二个print却打不出结果。
说什么  acess violation................
