大神们帮忙啊，先求平均，再求经向平均，总出错

梦纯

各位好，麻烦各位了！
HDF5格式的数据：
q file:
Descriptor:wind_vapor_geo.h5
  Binary:wind_vapor_geo.h5
  Type = Gridded
  Xsize = 280  Ysize = 200  Zsize = 10  Tsize = 605  Esize = 1
  Number of Variables = 7
     geo  10  t,z,y,x  geopotential-height
     sfclat  0  y,x  latitude
     sfclon  0  y,x  longitude
     u  10  t,z,y,x  u
     v  10  t,z,y,x  v
     vapor  10  t,z,y,x  vapor-mixing-ratio

     w  10  t,z,y,x  w
求时间平均后，再求经向平均，gs文件如下：


'reinit'
'sdfope  d:/wind_vapor_geo.h5'
'sdfopen d:/wind_vapor_geo_01.h5'


'set vpage 0.2  11  0.2 8.5'
t1=369

t2=492


'set dfile 1'
'set parea 1  5   1  7.5 '
'set grads off'
'set grid off'
'set xlevs 80 90 100 110 120 130'





'define n1=ave(w.1,t=t1,t=t2)'
'set lon 105 123'
'set lev 1000 100'
'set zlog on'
'set gxout shaded'
'set display color white'
'd ave(n1,lat=30,lat=40)'
'cbarn 0.7 0 5.5 1.8'
'draw title w '






'set dfile 2'
'set parea 6 10 1 7.5'
'set grads off'
'set grid off'
'set xlevs 80 90 100 110 120 130'


'define n2=ave(w.2,t=t1,t=t2)'
'set lon 105 123'
'set lev 1000 100'
'set zlog on'
'set gxout shaded'
'd ave(n2,lat=30,lat=40)'
'draw title w(topo-25%)'
'cbarn 0.7 0 5.5 1.8'


'set string 1 tc 10'
'set strsiz 0.25 0.25'
'set t 't1
'q time'
x1=sublin(result ,1)
t0=substr(x1,13,7)


'draw string  5.5  6.8 30~40`3.`1N w Comparisons(gpm)'


'printim 't0'_w.png white'


出错信息是：

Syntax Error:  Invalid dimension expression

求教各位大神，哪里出错了呀？？？      那四个ave函数该如何设置呢？多谢各位了！

我错了，应该是：
'define n2=ave(ave(w.2,lat=30,lat=40),t='t1',t='t2')'，就好了
