We consider a multicomponent liquid in cylindrical pore and find density profiles for this system with the external field applied in the plate perpendicular to the main axis of a cylinder. Due to this field density distribution is non-homogeneous. To find density profiles we use an approximation of weak non-uniformity under which energy of the system expanded on density deviations up to second-order terms. Solutions are found in the general case and for uniform (gravitational) field. Also we investigate wall influence on density profiles.
