摘要
为了探究大学本科环境物理学的实验教学难点——综合性实验,设计了以移动通信基站及高压输送变电站为代表的电磁环境污染测量综合性实验。分析了电磁辐射空间分布特征、变化规律及发展趋势,研究结果表明,射频电场强度和工频电磁场强度符合国家标准限值。将科研项目纳入本科生实验教学,有助于培养学生的创新能力。
In order to explore the comprehensive experiment,which is a difficult point in the experimental teaching of environmental physics for undergraduates,a comprehensive experiment of electromagnetic environmental pollution measurement,represented by mobile communication base station and high-voltage transmission substation,is designed.The results show that the intensity of RF electric field and power frequency electromagnetic field meet the national standard limits.It is helpful to cultivate students'innovative ability to bring scientific research projects into undergraduate experimental teaching.
