Abstrakty
A tow pomeron model is used to analyze the distribution of the ρ mesons electroproduction cross section with energy for different Q2. It is found that the steepness in the energy distribution can be attributed to the increase of the respective weight of the hard pomeron to the soft pomeron with increasing Q2. Using some suitable functions to fit the variations of the weights with Q2, a remarkable agreement with the experimental data is achieved.
