Based on finite element method, this paper proposes two EFI research methods, field-circuit coupling method and equivalent circuit method. The average EFI of the inner surface of the outer semi-conducting shield can be calculated from the current in the measuring circuit. The relative error between these two methods is about 15%, which roughly proves the consistency of the two methods. Further practical application research enables online monitoring of cable joints.展开更多

Though somewhat a sub-nation since its handover to China in 1999, the Macao Special Administrative Region Government （MSARG） finds it imperative to apply strategic communication to its place branding in its regional and international communities. Taking on the former Portuguese colony for an in-depth analysis, this study describes the perception of, knowledge about, and practice on strategic communication by the MSARG communication officials. The findings, though limited, seem reconcilable with the analytical assumptions of strategic communication studies in the west.展开更多
