Abstract
Based on a modulation model of nonlinear parametric instability, some theoretical expectation of statistical relation of solar radio spikes have been obtained. It is shown that the modulation amplitude of spikes ΔS is approximately equal to the coherent flux of spikesS c , excited by the electron cyclotron maser (ECM) instability; the repetition rate of spikesR is proportional to the square root ofS c ; and the spikes phenomena can only display in the coherent emission with narrow frequency band. These theoretical expectation are consistent qualitatively with the present statistical relation and observational result of solar radio spikes.
