Partial mixing of a liquid in cross motion of the 
phases is considered. Part of the liquid () on a plate is 
totally mixed, while the other part (1 - ) moves 
in the regime of ideal displacement; the degree of mixing is determined 
by the relation of these parts. The composition of a vapor after the 
plate is taken to be equal to the average value of the compositions 
of the vapor that come out of the initial and final portions of the 
plate in the direction of liquid motion. After an ideal plate these 
compositions are in equilibrium with the arriving and leaving liquid, 
respectively. The analytical dependences of the efficiency on the 
parameters of a real plate are obtained. The equality of the efficiencies 
in the vapor and liquid phases is proved. Certain particular and limiting 
cases of applicability of the complex model are considered.
