The spin-orbital energy gap in a one-dimensional spin-orbital model deduced from a degenerate Hubbard model with intrasite Hund rule coupling is studied.

Study on coupling characteristics of contactless power supply system for moving apparatus;

Numerical calculation on a rocket-based combined-cycle(RBCC)powered cruise vehicle has been done to analyze the coupling characteristics based on 2-D inviscid compressible flow theory and one-step finite rate chemistry model.

UV uniform exposure can effectively vary the coupling characteristics of the annealed long period gratings (LPGs) in hydrogen loaded fiber.

Relationship of relative gain and interaction characteristic of pipe network is analysed, to probe into the credibility of pressure difference control and to improve its energy-saving effects,relative gain of a air-conditioning water system is calculated , influence of pressure difference setpoint and its position to interaction characteristic of each branch is also discusseded.

An analysis of the mutual coupling between the coaxial multi-mode horn of two chokes in the near field;

Using progress of diffraction optics elements, analyzed the coupling future of Laser beam and optical fiber, experimented on optimize value and interrelated factors that light beam transform in optical fiber, and discussed the application of light beam commutation in laser flexible machining PCB.
