为了观察电磁脉冲（ＥＭＰ）对小鼠学习记忆和探究反射的影响，采用经典的Ｙ型迷路法和改良的开阔法（ｏｐｅｎｆｉｅｌｄｍｅｔｈｏｄ），检测三种电场强度的ＥＭＰ辐照后１ｄ内、１周和４周三个时间点小鼠学习记忆和探究反射。结果发现，与对照组相比，辐照后１周４０ｋＶ·ｍ１组小鼠学习和记忆成绩降低（Ｐ＜０．０５），８０ｋＶ·ｍ１组小鼠学习成绩降低（Ｐ＜０．０５）；与对照组比较，辐照后１天内三种电场强度辐照组小鼠探究反射均下降（Ｐ＜０．０５），以４０ｋＶ·ｍ－１组更明显。辐照后１周８０ｋＶ·ｍ１组小鼠探究反射下降（Ｐ＜０．０５）。由此可见，电磁脉冲可能影响小鼠的学习记忆和探究能力。
In order to observe the effect of electromagnetic pulse (EMP) on learning and memory and investigative reflex in mice, the classic Y-shaped labyrinth and open field method were used to detect the intensity of three electric fields within 1 day, Three weeks after 4 weeks mice learn to remember and explore the reflex. The results showed that compared with the control group, the scores of learning and memory of 40kV · m1 mice decreased (P <0.05) and the scores of 80kV · m1 mice decreased (P0.01) .05). Compared with the control group, the inbred reflexes of mice irradiated by three kinds of electric field intensities decreased (P <0.05) within one day after irradiation, especially in 40kV · m-1 group. One week after irradiation, 80kV · m-1 mice showed lower reflex (P <0.05). Thus, electromagnetic pulse may affect the learning and memory and exploring ability of mice.
