摘要：

We have constructed a greatly simplified theory for the heliospheric modulation of high-energy cosmic rays in which no adjustable parameters are used. The only parameter k, which characterizes the degree of regularity of the interplanetary magnetic field, varies in the model in a definite way with solar cycle phase. The approximations used lead to solutions expressed in terms of elementary functions. The role of the magnetic drift of particles has been revealed. Quantitative agreement with the observed cosmic-ray variations has been achieved.
