摘要
为了增加光泵磁共振实验的设计性和研究性,本实验不提供小磁针,让学生在没有磁针的情况下,通过对实验原理的充分理解和把握,由自己通过实验来判断扫场及线圈产生的水平场的方向。文章介绍了没有磁针的情况下,用光抽运信号判定扫场方向及由光泵磁共振信号判断线圈产生的水平场方向的依据和方法。
In order to increase the design and the research of the optical pump magnetic resonance experiment, this experiment does not provide small magnetic needle. In this situation, let students by themselves to judge the direction of scanning field and horizontal field of the coil on the base of full understanding and holding the principle of experiment. This article introduced the gist and method of judging the direction of scanning field with the optical pumping signal and the direction of horizontal field of winding produced with the optical pumped magnetic resonance signal in the situation of not having magnetic needle.
