We study galactic cosmic ray (GCR) modulation during solar cycle 24. For this study we utilize neutron monitor data together with sunspot number (SSN) and 10.7 cm solar radio flux (SRF) data. We plot hysteresis curve between the GCR intensity and SSN, and GCR intensity and SRF. We performed time-lag correlation analysis to determine the time lag between GCR intensity and solar activity parameters. The time lag is determined not only for the whole solar cycle, but also during the two polarity states of the heliosphere (A<0 and A>0) in solar cycle 24. We notice differences in time lags during two polarity epochs of the solar cycle. We discuss these differences in the light of existing modulation models. We compare the results of this very weak solar activity cycle with the corresponding results reported for the previous comparatively more active solar cycles.

我们研究了太阳周期 24 期间的银河宇宙射线 (GCR) 调制。在这项研究中，我们利用中子监测数据以及太阳黑子数 (SSN) 和 10.7 厘米太阳射电通量 (SRF) 数据。我们绘制了 GCR 强度和 SSN 以及 GCR 强度和 SRF 之间的滞后曲线。我们进行了时滞相关分析，以确定 GCR 强度和太阳活动参数之间的时滞。时间滞后不仅在整个太阳周期内确定，而且在太阳活动周期 24 中日光层的两个极性状态（A<0 和 A>0）期间也确定。我们注意到太阳在两个极性时期的时间滞后差异循环。我们根据现有的调制模型讨论这些差异。
