| 中文摘要: |
| 无自旋交换弛豫（SERF）原子磁强计是一种灵敏度非常高的磁强计，而剩余磁场强度是影响SERF原子磁强计灵敏度的主要因素之一。为此，提出了一种SERF原子磁强计三轴磁场顺序补偿方法，该方法将剩磁范围分为三个部分，每个部分对应不同的补偿方式，并且使用软件对顺序补偿的整个过程进行了仿真实验。实验表明，该方法可以不受补偿前原始剩磁大小的影响，更具有普适性。 |

| The spin exchange relaxation free (SERF) atomic magnetometer is a very sensitive magnetometer. The strength of the residual magnetic field is one of the main factors affecting the sensitivity of the SERF atomic magnetometer. For this reason, a three-axis magnetic field sequential compensation method of the SERF atomic magnetometer is proposed. The method divides the remanence range into three parts. Each part corresponds to a different compensation method, and the whole process of sequential compensation is simulated by software. Experiments show that this method does not consider the size of the original remanence before compensation and is more universal. |
