| 摘 要： | 迄今为止使用的磁场线圈间距全为固定式,而环境又几乎全有较大的磁场梯度。因此理论上设计的均匀性、正交性等随着时空或相辅条件变化而变化时,就不能实施监测和校正。该系统的研制使线圈间距由固定变成相对均位调控或不对称调控,可确实补偿客观存在的磁场梯度。从而提高了监测精度,也有效地解决了磁场梯度的校正问题,填补了国内这一应用领域的空白。

| Abstract: | Before the successful development of this system, the coil spacing in the magnetic field coil system was fixed and there are large magnetic gradients in almost all the environment; therefore, the uniformity and orthogonality designed theoretically were not adjustable or able to be supervised or corrected when the environment changed. The development of this system makes the coil spacing relatively equally adjustable or asymmetrically adjustable and so can compensate the magnetic gradient in the objectivc environment,thus raising the precision of supervision, solving the problem of the magnetic gradient correction effectively and filling in the gap in this application in China. |
