核磁共振磁强计(NMR磁强计)由于其测量精度高,在近代得到了日益广泛的应用和发展。本文介绍NMR磁强计在提高性能(提高信噪比、扩大量限、提高灵敏度、自动搜索、自功锁定、自动跟踪、直接读数及简单化、小型化等)中可能采取的几种方案。并介绍为能在远距离及低温条件下测量磁场时所存在的问题和解决方案。文章最后介绍了流水式NMR磁强计的原理及其优缺点。
Nuclear Magnetic Resonance Magnetometer (NMR magnetometer) due to its high measurement accuracy, has been increasingly widely used in modern times and development. This article describes several options that NMR magnetometers can take to improve performance (increased signal-to-noise ratio, expanded quantum limits, increased sensitivity, automatic search, self-locking, automatic tracking, direct reading, simplification, miniaturization, etc.) And describes the problems and solutions that exist when measuring magnetic fields over long distances and at low temperatures. Finally, the article introduces the principle of flow-through NMR magnetometer and its advantages and disadvantages.
