摘要

利用莫斯科国立大学（MSU）的广泛风淋阵（EAS）阵列研究了能量大于1014 eV的广泛风淋阵（EASes）中粒子的时间分布。延迟粒子在所有ease中约占3.5%。讨论了1986年至1990年观测到的闪光频率，并在1987年达到最大值。闪衰的精细结构由一系列周期为~ 4天和持续时间为~ 32.5天的准周期阻尼振荡爆发组成。EAS注册频率在统计误差范围内没有变化。

Search for Variations in the Frequency of Registering Delayed Particles at the MSU Extensive Air Shower Array

The Moscow State University (MSU) Extensive Air Shower (EAS) array is used to study the temporal distributions of particles in extensive air showers (EASes) with energies greater than 10¹⁴ eV. Delayed particles are registered in ~3.5% of all EASes. The flash observed in the frequency of their registration from 1986 to 1990 with a maximum in 1987 is discussed. The fine structure of flash decay consists of a series of bursts of quasi-periodic damped oscillations with periods of ∼4 days and durations of ∼32.5 days. The frequency of EAS registration does not change within the limits of statistical error.
