All-angle behavior of the cross sections in two-body scattering is examined by a counting law on the basis of the string structure in a hadron. Then the fixed-angle scaling is interpreted as the contribution of strings at large momentum transfer. This counting law contains a good crossing relation, and predicts the energy dependence and the angular distribution of the cross sections in various processes. In charge-exchange processes the applicability of this model to all-angle cross sections is examined. This model gives a good explanation of the large ratio (dsigma( pp)/dt)/(dsigma( p-barp)/dt), the asymmetric distribution of dsigma(K/sup -/p ..-->.. ..pi../sup +/..sigma../sup -/)/dt, and the transition behavior between the fixed-angle scaling and the Regge-pole-like behavior.
