A Study on an Anticyclonic-Cyclonic Eddy Pair Off Fraser Island, Australia
Frontiers in Marine Science, 2020 This research examines a cyclonic-anticyclonic eddy (AE) pair off Fraser Island next to the eastern Australian coast in 2009 using the Bluelink Reanalysis data, where the local eddies are poorly understood. This eddy pair formed in July and dissipated in

Characteristics of Eddy Current Attenuation and Thickness Measurement of Metallic Plate
Chinese Journal of Mechanical Engineering, 2019 In eddy current testing, the law of attenuation of eddy current (EC) is of great concern. In conductive half space under the excitation of uniform magnetic field, the EC density decreases exponentially in the depth direction.
