2.1 The postulate In 1864, James Clerk Maxwell proposed one of the most successful theories in the history of science. In a famous memoir to the Royal Society [125] he presented nine equations summarizing all known laws on electricity and magnetism. This was more than a mere cataloging of the laws of nature. By postulating the need for an additional term to make the set of equations self-consistent

One of the most powerful tools for the analysis of electromagnetics problems is the integral solution to Maxwell’s equations formulated by Stratton and Chu [187, 188]. These authors used the vector Green’s theorem to solve for E˜ and H˜ in much the same way as is done in static fields with the scalar Green’s theorem. An alternative approach is to use the Lorentz reciprocity theorem of § 4.10.2, as done by Fradin [74]. The reciprocity

The static electromagnetic field 3.1 Static fields and steady currents Perhaps the most carefully studied area of electromagnetics is that in which the fields are time-invariant. This area, known generally as statics, offers (1)the most direct op￾portunities for solution of the governing equations, and (2)the clearest physical pictures

目前，熔盐电化学冶金普遍采用炭素阳极，阳极CO2产物是重要的碳排放源。若在高温熔盐体系中使用惰性析氧阳极，则可实现熔盐电解过程低碳排放。因此，开发适用于熔盐电解体系的惰性阳极至关重要，也是近年来国内外研究热点。本文首先综述了各种高温熔盐体系惰性阳极的研究进展，所涉及熔盐体系包括：铝电解氟化物盐、CaCl2熔盐、碳酸盐和熔融氧化物等。另外，近年来月球开发利用受到广泛关注，太阳能驱动的月壤原位熔盐电化学制氧，将是支撑人类未来月面生存氧气需求的重要方法之一，故惰性析氧阳极不可或缺。因此，本文也简要综述了基于惰性阳极的月壤电解制氧技术
