The influence of stochastic heterogeneities on a superfluidity in two-layer systems in a strong perpendicular magnetic field is theoretically analysed. Ii is shown that the ionized impurities and the curvature of layers can essentially reduce a density of a superfluid flow of e-h pairs. As the result, electron-hole superfluidity exists in a limited range of interlayer distances. Therefore, in experiment a critical condition for the observation of e-h superfluidity is the high degree of homogeneity of semiconductor two-well GaAs/AlGaAs-heterostructures. 1.2. The process of producing hydrogen from the water vapor running through the heated iron or carbon pipe is theoretically investigated. This process includes a homogeneous reaction of a high-temperature dissociation/recombination of the water vapor, combined diffusive-hydrodynamic mass transfer of the released oxygen to the wall of a pipe, heterogeneous oxidation reaction of a pipe-wall material with the oxygen absorption and, at last, mass transfer of the released hydrogen together with the residual of the water vapor and oxygen. The approximate analytical solution is obtained which gives an output of hydrogen as function of initial water vapor concentration and two dimensionless combinations of process parameters. This solution is well matched to the numerical solution.
