| 5 | Giant Magneto-impedance Effect in Composite Wires with Different Core Layer显示文摘Composite structure materials were potential sensing elements for magnetic sensors due to Giant magnetoimpedance(GMI) effect. Two kinds of composite wires with different magnetic/non-magnetic structures were fabricated by using electroless deposition methods and the magnetoimpedance properties were investigated. The maximum GMI ratio of 114% was acquired at 60 MHz in the composite wires with a ferromagnetic core, whereas, 116% of maximum GMI ratio was found in the composite wires with a conductive core at low frequency of 600 k Hz. These results exhibit that the GMI ratio reaches the maximum when magnetoresistance ratio ?R/R and magnetoinductance ratio ?X/X make the comparative contributions to the total magnetoimpedance(MI). The obvious GMI effect obtained in the composite wires with conductive core frequency may provide a candidate for applications in magnetic sensors, especially at low frequencies. | R.L.Wang X.Li X.H.Kong Y.X.Guo J.Z.Ruan Z.J.Zhao | 2013 | Nano-Micro Letters2013，5，2： | 1 |
| 6 | One kind motion of controllable constrained Birkhoffian system:the absence of constraints显示文摘This paper is devoted to discuss the motion of controllable constrained Birkhoffian system along with its absence of constraints.The first step is to establish the autonomous and non-autonomous differential equations of motion of the system,based on Pfaff-Birkhoff principle.Secondly,the existence of constraint multipliers are exhaustively discussed.Thirdly,the definition of one kind motion of the system,called free motion,is given,which is described and analyzed by the absence of constraints that are determined by constraint multipliers.Lemma 2 illustrates that one system can realize its free motion by selecting proper control parameters.In particular,theorem 2 provides that one system can naturally realize free motion when we consider the integral of the unconstrained Birkhoffian system as the constraints of constrained Birkhoffian system.Finally,the results obtained are illustrated by several examples. | J.Chen F.X.Mei S.X.Liu Y.X.Guo | 2020 | Acta Mechanica Sinica2020，36，3： | 0 |
| 7 | Enhanced pitting corrosion resistance of a Zr-based metallic glass by ultraviolet light irradiation显示文摘The influence of ultraviolet light irradiation on the pitting corrosion performance of a Zr_(2)Ni metallic glass was examined using electrochemical methods and immersion test in 0.05 mol/L NaCl solution.From the results of potentiostatic polarization,the pitting potential of the ultraviolet light-irradiated sample shifted positively with a value of~300 mV,revealing the enhanced pitting corrosion resistance of the samples.The corrosion morphology after the immersion test also demonstrated lower degree of corrosion damage and improved pitting resistance of the sample with ultraviolet light irradiation.X-ray photoelectron spectroscopy analysis revealed more zirconium enrichment in the passive film and no chloride ions adsorption for the samples with ultraviolet irradiation,accounting for the suppression of the pit generation and growth.Our findings indicate that ultraviolet light irradiation improves the pitting corrosion resistance of the Zr-based metallic glasses,which are promising structural materials to be used in corrosion environments with high ultraviolet irradiation. | Z.Chen D.P.Wang S.Wang Y.X.Geng Y.X.Guo Y.C.Wu Z.G.Liu Y.Y.Zhang Y.X.Wang | 2023 | Journal of Iron and Steel Research(International)2023，30，8： | 0 |
