Amorphous (Nd,Pr)13Fe80Nb1B6 ribbons were crystallized at 670-730℃ for 5-25 min to study the effects of isothermal crystallization on their behavior and magnet
A novel soft initial-rotation control system and an Hoo robust constant rotational speed controller (RCRSC) for a rotational MEMS (micro-electro-mechanical syst
This paper presents a new trajectory linearization control scheme for a class of nonlinear systems subject to harmonic disturbance. It is supposed that the freq
The SiC gradiently coated carbon fiber/carbon (Cf/C) composites were prepared by a two-step rapid chemical liquid depo-sition (RCLD) method. The microstructure
The flotation of niobite, fersmite, and ilmenorutile was studied using 3 collectors with various concentration and pulp pH. The collecting property of different
The effect of high magnetic fields on the morphology of Al-Mn phases was investigated. It is found that the tropism and the alignment of Al6Mn precipitated phas
To meet the demands of continuous stream-line for component production in the thixo-forming industry, billet heating should be of high quality and in a controll
