Oxide semiconductor alloys of x(LiGaO2)1/2-(1−x)ZnO were fabricated by the solid state reaction between β-LiGaO2 and ZnO and rf-magnetron sputtering. For the solid state reaction, the wurtzite-type single phases were obtained in the composition range of x⩽0.38. The formation range of the alloys was wider than that of the (Mg1−x Zn x )O system, because the β-LiGaO2 possesses a wurtzite-derived structure and approximately the same lattice constants with ZnO. The electrical resistivity and energy band gap of the 0.38(LiGaO2)1/2-0.62ZnO alloyed ceramic were 0.45 Ωcm and 3.7 eV, respectively, at room temperature. For the alloying by sputtering, the films consisting of the wurtzite-type single phase were obtained over the entire composition range of x(LiGaO2)1/2-(1−x)ZnO. The energy band gap was controllable in the range from 3.3 to 5.6 eV. For the as-deposited film fabricated using the 0.4(LiGaO2)1/2-0.6ZnO alloyed ceramic target, the energy band gap was 3.74 eV, and the electrical resistivity, carrier density and the Hall mobility at room temperature were 3.6 Ωcm, 3.4×1017 cm−3 and 5.6 cm2 V−1 s−1, respectively.

Ice-shedding will cause the violent oscillation of the lines, and makes the conductors jumping up and down. The jumping of the conductors reduces the phase-to-phase clearance, even leads to interphase flashover and structural destructivition. Aiming at the difficulties in measuring the vibration problem caused by ice-shedding of conductors, A sensing meathod on binocular vision theory is presented. The restriction between conductors in 3D space and image in camera are used to get the measurement model, which is based on binocular vision theory. The measurement mathematical model of conductor is soluted by standard length binocular visual system calibration meathod, then, the 3D information of conductor is recoveried. In the measurement experiment, the binocular vision measurement system is established. The experiment results indicate that the measuring system is both simple in structure and convenied for the vibration measurement of ice-shedding conductor.

This paper introduces a novel hybrid FEM-BEM method for calculating 3D eddy cur-rent field. In the eddy current region, the eddy current density J is solved by the finite element method (FEM) which is discretized by brick finite element mesh, while in the eddy current free re-gion, the magnetic field intensity H is solved by the boundary element method (BEM) which is dis-cretized by rectangular boundary element mesh. Under the boundary conditions, an algebraic equation group is obtained that only includes J by eliminating H. This method has many advan-tages over traditional ones, such as fewer variables, more convenient coupling between the FEM and the BEM and wider application to multiply-connected regions. The calculated values of two models are in good agreement with experimental results. This shows the validity of our method.
