Thanks for the help!!!

I encountered the other problem that when I display a set of volumes (
(x,y,z)->(concentration) ) and
map the "concentration" to Display.RGBA. To make a "foggy" effect in low
concentration values,
I set the RGBA table for each volume. When I displayed multiple sets (
multiple maps of RGBA ),
the transparency didn't work well:
    Transparent area in a set shelters other other volume set data. It looks
like a front invisible object cull out a back object,
but I exepct it should not cull out any object in the back if it is
"transparent".

Do you have any solution for it?

no, this is a Java 3D issue.  The transparency will depend
on the order in which the DataReferences were added.

See:

for an explanation.
