  The situation of the metastable phase decay on the several types of
heterogeneous centers is considered. The iteration procedure is formulated and
with the help of the avalanche consumption property all iterations can be
calculated. The same procedure is done for the monodisperse approximation. Here
the avalnche consumption is also used to calculate iterations. It is shown that
all iterations with a high number have one and the same structure. It allows to
obtain the functional form of solution and to formulate directly an equation on
the parameter of this functional form.
