Unmagnetized current transformer and voltage transformer are micro current and micro voltage output equipment with little weak points of saturation magnetization existed intraditional electro magnetic current transformer and voltage transformer.
The paper introduces the technical research results of some new type vibration dampers, including the structure and feature of current-controlled fluid damper, throttle type magnetic fluid adjustable damper, double-cylinder hydraulic gas damper, magnetic damper, adjustable damper, semi-active suspension damper, "ceiling" damper and etc.
Then the equivalent method is employed to deduce themathematical model of the hybrid suspension system step by step, the levitationforces of the hybrid suspension system at different air-gaps are simulated, which aremuch larger than those of the pure electrical magnetic suspension system.
The distributing and changing rule of the vehicle’s air-gap magnetic fields are of great important influence on the performance of vehicle’s levitation, advancing, guiding and the generating electricity system on board. The study of the EMS high-speed magnetic levitation vehicles’electromagnetic systems has important directive meaning to the design and control of the vehicle’s electromagnetic systems.
The numerical techniques for simulating the transient behaviors of a maglev train are studied in this thesis. To this end, the magnetic suspension technology and its successful application on the magnetic levitation vehicle is briefly summarized.
In the second part, where we explore connections with Maxwell's equations, the main novelty is the treatment of the corresponding electro-magnetic boundary value problem by recasting it as a 'half' Dirichlet problem for a suitable Dirac operator.
At the end of the article, the method is tested on real magnetic field data measured by the German geoscientific research satellite CHAMP.
The stereo-structures of Roridin P and Isororidin P were established on the basis of one- and two-dimensional nuclear magnetic resonance (NMR) spectral analyses.
The synthesized compounds have been characterized on the basis of elemental analyses, infrared spectroscopy (IR), and nuclear magnetic resonance (NMR).
Two compounds were designed, synthesized, and characterized by 1H-nuclear magnetic resonance (1H-NMR), ultraviolet (UV)-visible, and matrix-assisted laser desorption/ionization (MALDI) mass spectra.
