Popis:	The anisotropy of the electrical conductivity and the electrical piezoeffect due to this anisotropy is found in a uniaxially deformed thin polycrystalline Bi film. The symmetrical and antisymmetrical parts of the nondiagonal elements of the conductivity tensor for various directions of the deformation in the presence of an external magnetic field are investigated. It is shown that all features of the anisotropy can be qualitatively explained in terms of electron repopulation between the L-valleys in the randomly orientated and deformed Bi microcrystallites. Possible ways of obtaining higher anisotropy in deformed films are discussed. [Russian Text Ignored].
