研究地磁场环境中钢试件在动拉伸载荷作用下表面弱磁信号的变化以及磁记忆效应。
RESULTS: Exposure time had more effects on the mice learning memory when the product of magnetic field intensity and magnetic exposure time was equal.
结果：恒定磁场强度与磁场暴露时间的乘积相等时，大剂量、短时间暴露比小剂量、长时间暴露对小鼠学习记忆能力的影响要小；
This paper studies the effects of the placement direction to the magnetic memory signals through experiments.
