I understood what you're trying to do, but this appears to be a bug in
version 1.2. What you've written (using '&') works on trunk/, but not
on version 1.2.
As a workaround, you can do
from fipy.terms.explicitSourceTerm import _ExplicitSourceTerm
eqp=ImplicitDiffusionTerm(coeff=1)==_ExplicitSourceTerm(q1s+q2s)
eqphi=TransientTerm(coeff=2)==_ExplicitSourceTerm(q1s-q2s)
