本文在单色散关系的基础上提出了一个得到散射振幅的近似方法。原则上,这个方法能用于讨论高能和低能散射振幅的行为。用两个参数对高能π±p,K±p,pp和pp散射实验作了初步比较,发现理论和实验是符合的。Basing on the dispersion relation, an approximate method is suggested to obtain the scattering amplitudes. In principle we can apply this method to the study of the amplitude behaviour of low and high energy scattering. For high energy π±p, K±p, pp, and pp scattering, the primary comparison with experiments is made by two parameters. It is found that the theory agrees with experiments.
