Quasiclassical equations describing nonstationary and nonequilibrium phenomena in structures containing boundaries between metals are derived, and the boundary conditions (at the metal interface) for these equations are found. The boundary conditions are derived for an arbitrary transparency (and arbitrary shape) of the potential barrier, whose appearance at the boundary may be due to a difference in the parameters of the contiguous metals, the presence of a dielectric layer between the metals, etc. In the case of tunnel junctions the obtained boundary conditions allow one to easily derive for the current an expression that coincides with those obtained on the basis of the method of tunneling Hamiltonians. The general results are used to study the properties of different types of constrictions (N/sub 1/cN/sub 2/, ScN, S/sub 1/cS/sub 2/) with allowance for electron reflection at the metal interface. The case of ''pure'' constrictions (whose characteristic dimension a<
