This theory is free from various logical imperfections, that may be found in the approaches of earlier researchers. On the base of this theory the equations of shells of revolution are built. The equations of cylindrical shell are compared by a number of properties with the equations of other researchers and with elasticity equations of 3-dimensional tube. Important quality decisions are stated.19 pages, 4 figuresMathematical PhysicsCondensed Matter74K25; 53A45; 53A05text
