[Xy-pic] simple question? uniform space between objects in xymatrix

[Roger Hart]

Forgive me for posting to a list I have just subscribed to, but I have 
spent considerably more time than I'd like to admit trying to figure 
out what I hope should be something very simple: I would just like to 
format xymatrix so that the space between the objects, which vary in 
size, is uniform. For example, I have a 4x3 matrix, with entries about 
the size shown below, varying in height from one to four Chinese 
characters, which I would like to be formatted as follows,

X	X	X

X	X	X
X	X	X

X	X	X
X	X	X

X	X	X
X	X	X
X	X	X
X	X	X

That is, I would simply like to have the spaces between all of the rows 
approximately the same. I have repeatedly read through xy-pic Reference 
Manual and Guide, and have tried all kinds of combinations of @, @C, 
@R, @M, @!, @!0, all kinds of add ops, +, -=, +=, -, =, and various 
dimensions, but I'm not a TeX or LaTeX expert, and in the end, I still 
don't really understand what I'm doing, or even what to expect when I 
make a change. Instead I get something like,

X	X	X


X	X	X
X	X	X

X	X	X
X	X	X




X	X	X
X	X	X
X	X	X
X	X	X


Is there a simple way to set xymatrix so there is a column space of say 
2mm and row space of 2mm, no matter what the size of the entries? Are 
there other sources I can look at for documentation?

If you reply, please also cc: a copy of the email message directly to 
me, if you could.

Thanks very much,

Roger
