Use "pdepe".
You will need to specify four boundary conditions for this solver, although only two for the T equation were necessary.
As artificial condition for alpha, you could use d(alpha)/dz =0 at both ends.

how can i write the artificial condition d(alpha)/dz=0? the matrix "f" used in pdepe code is [b*(dT/dz) ; 0] .*dudz in this case and I have to write this type of conditions p(x,t,u)+q(x,t)*f(x,t,u,du/dx)=0.
