2、al conditions, high magnetic fields become one of the most important tools of many scientific researches. Researching deeply make more stringent requirements for the space, time, shape and so on of the magnetic fields. A

3、t the same time ,it also requires more to the measurement of high magnetic fields. As compared to the traditional measuring methods of electromagnetic induction and magneto-optic effect, it is possible that using the ato

4、mic parameters to measure the high magnetic fields with the development of modern physics. Therefore this paper elaborates a measurement of high magnetic fields based on the principle of nuclear magnetic resonance. Accor

5、ding to the fundamental formulae of nuclear magnetic resonance, we obtain the theoretical foundation for the measurement and prove it is feasible. In order to improve the accuracy of measurement used nuclear magnetic re

6、sonance, this paper studies that the effects of high magnetic fields to nuclear magnetic shielding of the nuclear magnetic resonance signal. In the past, when calculating the nuclear magnetic shielding, the magnetic fiel

7、ds are usually under 10T, so the square of magnetic strength is ignored. In this paper, we analysis the correction of second-order perturbation from the square of magnetic strength further. And we calculate the correctio
