Influence of Emitter Surface Roughness and Emission Inhomogeneity on Efficiency and Stability of High Power Fusion Gyrotrons

The increasing demand for powerful, reliable, and efficient gyrotron oscillators for Electron Cyclotron Resonance Heating (ECRH) in fusion plasma experiments requires a close look at the various factors in gyrotrons that determine gyrotron performance. In this frame, the influence of emitter surface roughness, emission inhomogeneity, and secondary electron generation on gyrotron operation is presented, with focus on Low Frequency Oscillations (LFOs) and Electron Beam Halo (EBH) generation

Hypergeometric function expressions for the molecule-micropore Lennard--Jones potential

We present hypergeometric function expressions for the molecule-micropore Lennard--Jones potential in cylindrical pores, in which the cylindrical wall can be a surface, or have thickness or have infinite thickness. These expressions are useful in theoretical study and computer simulations of fluids in micropore of circular cross sections

An Innovative Practice System of Information Management and Information System Specialty Based on Actual Projects

The practical teaching is the key link of training the students’ practical and creative ability in major of information management and information system. On the basis of analyzing the training goal and social demand of the major, an innovative practice system based on actual projects is constructed to solve the main problems exist in the practical teaching, by combining with the successful experience of the practical teaching innovation in Wuhan University of Science and Technology. The system provides a good practical teaching environment and an innovation practical platform for the cultivation of high quality innovation talents. To study in actual projects will accumulate the students’ project experience, cultivate their innovation consciousness and promote their competition ability

A Study on Project-Driven Practice and Innovation Abilities of IT Students’ Club

IT students’ clubs play an irreplaceable role in training students’ innovation and practical abilities. Through questionnaires and interviews, the paper analyzes students’ participation in IT clubs, the training of students’ innovation and practical abilities and the problems existing in the organization management of clubs. By referring to the successful experience of Wuhan University of Science and Technology in the practice teaching reform, a “project-driven” system for training practice and innovation abilities, which focused on training students’ innovation spirit and practical abilities, was established and achieved remarkable success
