摘要：
The time variation of the galactic cosmic rays (GCR) (1958–2006) is described using solar activity indices in the form Zα, Zα exp[−(φ/φ0)β], where Z and φ are one of the solar activity indices and the heliolatitude of sunspots; α, β, and φ0 are the optimum parameters found by the least-squares method. The time variation of the GCR flux is satisfactorily described, the role of the active region heliolatitude in the index in relation to the cosmic ray modulation is revealed.
