在现代生活中，我们被主要使用电力形式的能源所引起的电磁噪音所包围。这种情况是由于理论上不了解噪声而造成的。千叶重离子医疗加速器（HIMAC）建设引入了降噪新实践。关键概念是对称三线电路，将电源、噪声滤波器和磁铁布置在第三条中心接地线周围。持续的理论努力迫使我们找到一种新的电路理论，涉及多导体传输线系统，从麦克斯韦方程组开始，没有任何近似。我们讨论所有这些实验和理论发展的本质，希望不仅从电源中消除不必要的电磁噪声，而且从所有电子设备中消除不必要的电磁噪声。新导出的多导体传输线电路理论具有普适性，并确立了降噪实践的有效性。
In modern life, we are surrounded by and filled with electromagnetic noise caused by the dominant use of energy in the form of electricity. This situation is brought about by the fact that the noise is not understood theoretically. A new practice of noise reduction was introduced for the construction of Heavy Ion Medical Accelerator in Chiba (HIMAC). The key concept is a symmetric three-line circuit that arranges power supplies, noise filters and magnets around a third central ground line. A continuous theoretical effort forced us to find a new circuit theory involving a multiconductor transmission-line system starting from Maxwell’s equations without any approximation. We discuss the essence of all of these experimental and theoretical developments with the hope to remove unnecessary electromagnetic noise not only from power supplies, but also from all electric devices. The newly derived circuit theory of multiconductor transmission lines is universal, and establishes the validity of the practice of noise reduction.
