The circumstances surrounding the realisation that NMR signal reception could be quantified in a simple fundamental manner using Lorentz's Principle of Reciprocity are described. The poor signal-to-noise ratio of the first European superconducting magnet is identified as a major motivating factor, together with the author's need to understand phenomena at a basic level. A summary is then given of the thought processes leading to the very simple pseudo-static formula that has been the basis of signal-to-noise calculations for over a generation.
描述了以洛伦兹互易原理为简单基础实现 NMR 信号接收定量化这一认识过程。第一个欧洲超导磁体的信噪比较差被认为是一个主要的推动因素，同时作者也需要从基本层面理解现象。然后概述了导致非常简单的准静态公式的思维过程，该公式已成为超过一代人的信号噪声计算的基础。
