The study collated oscillations of body temperature of С57BL/6 mice and Roborovski hamsters (Phodopus roborovskii) in the period range of 100-240 min and fluctuations of the secondary cosmic rays reflected by neutron count rate of a neutron monitor at the Earth's surface. Cross-correlation of body temperature and neutron count rate data revealed their strong association only for simultaneous measurements. Collation of the phase of neutron count rate fluctuations with maxima of body temperature oscillations revealed the coincidence of the phases of both processes. There was a temporary connection between the periods of body temperature elevation and neutron count rate rise. Thus, not only the spectral parameters of biological and physical processes, but also their phases coincided, which corroborates the hypothesis on stimulating effect of increasing neutron count rate on activity of the animals.
该研究整理了 C57BL/6 小鼠和罗伯罗夫斯基仓鼠（Phodopus roborovskii）的体温波动在 100-240 分钟的周期范围内，以及地球表面中子监测仪的中子计数率所反映的二次宇宙射线的波动。体温和中子计数率数据的互相关分析仅在同时测量时显示出它们之间的强烈关联。将中子计数率波动的相位与体温波动的最大值进行对照，发现这两个过程的相位是一致的。体温升高和中子计数率上升的周期之间存在暂时的联系。因此，不仅生物和物理过程的谱参数，而且它们的相位都一致，这证实了增加中子计数率对动物活动的刺激效应的假设。
