Some problems of special relativity

The possibility to formulate special relativity based on generalized Lorentz transformations is discussed. The transformations have been obtained as a result of explicit consideration of conventional character of the concept of simultaneity of spatially separated events. They contain as a particular case (epsilon=1/2) usual Lorentz transformations, whereas epsilon not equal to 1/2 corresponds to inequality of physical process rates in opposite directions. These transformations provide for the quadratic form invariance that is defined by the covariant metric tensor g01 not equal to 0. The behaviour of moving clocks and measuring rods is considered, addition rule for velocities has been obtained
