摘要
探索了在原有实验基础上用电子自旋共振现象测量地磁场的新方法,较准确地测出地磁场水平、垂直分量,计算得出磁倾角,与标准值比较,相对误差分别为3.3%,1.9%,2.3%。该方法的突出优势在于用计算机代替人眼对信号的观测,克服了示波显示方法的弱点,实现了共振峰的客观判定,提高了判断的准确度。同其他传统测量方法相比,本测量方法简单,测量精度较高,是一种比较理想的地磁场测量方法。
This article introduces a new way to measure the geomagnetic field on the base of the original experiment by electron spin resonance phenomenon. The method can accurately measure the horizontal and vertical components of the geomagnetic field, and calculate the magnetic inclination. Compared with the standard values, relative errors are only 3. 3% ,1.9% ,2.3%. The outstanding advantage of the method lies on using the computer to replace the human eyes for signal observation. It can overcome weaknesses of the traditional oscilloscope display, objectively determine the formant, significantly improve the accuracy of judgment. Compared with other traditional measurement methods, it is an ideal method since it is more simple and has higher measurement accuracy.
