一、磁透镜实验仪的用途及其基本技术特性: 磁透镜是电子透镜中的一种,它与静电透镜一样,对电子都具有聚焦成象的性质。用本实验仪既可验证理论,使同学获得感性知识,进而加强理论和实践的结合,加深对基本概念的了介,同时又可以训练学生的实际操作能力。本实验仪主要作为《电子光学》课磁透镜章节的教学实验设备,同时也可以作为研究电子在电磁场中运动的有关课程的教学演示设备。
First, the use of magnetic lens test instrument and its basic technical characteristics: Magnetic lens is one of the electronic lens, which, like electrostatic lenses, have focused electronic properties of the image. The experimental instrument can verify the theory, so that students gain perceptual knowledge, thus strengthening the combination of theory and practice, deepen the introduction of the basic concepts, but also can train students’ practical ability. The experimental instrument mainly as “electronic optics” magnetic lens chapter of the teaching experiment equipment, but also can be used as a study of electronic movement in the electromagnetic field related teaching demonstration equipment.
