@Carl Love Thank's for answer. There is my file with function's, parameter's.

If i launch this file first time, i get mistake:

"Error, (in pdsolve/numeric/par_hyp) input system is too far from a 'standard' form (see ?pdsolve,numeric for more detail)".

If i launch second time, i got:

"Error, numeric exception: division by zero
Error, (in pdsolve/numeric/process_PDEs) number of dependent variables and number of PDE must be the same".

What i do wrong?!
