燒結鐵素體 的英文怎麼說
中文拼音 [shāojiētiěsùtǐ]
燒結鐵素體
英文
sintered ferrite-
The camber development mechanism and the influence factors were researched by geometry analysis, viscous analysis and sintering kinetics analysis. the camber model was established and the equation for calculating curvature of camber was proposed. the influence factors for camber involve the original size of composite, the sintering properties and the shrinkage mismatch between the two materials
從幾何學、粘彈性力學和燒結動力學的不同角度出發，探討了共燒翹曲形成機制和影響因素，建立了介電材料鐵氧體材料疊層共燒翹曲模型和翹曲曲率方程，揭示影響翹曲的因素為形狀尺寸因子，材料的燒結特性和異種材料之間的收縮率差，其中燒結過程的收縮率差是翹曲產生的根本因素，收縮率差越大，則翹曲曲率越大。The hexagonal barexfe, 2. xo, ( re denote la ^ nd > sm and gd ) ultrafine powders with m - type structure were firstly synthesized by a novel technique - - - - - - sol - gel combustion synthesis method which combines sol - gel method with low temperature combustion synthesis method. based on theoretical analysis and experimental study, the effects of the composition of the gel, the different kinds of intermediate, strength of solution, the amount of complexing agent, the different kinds of anions, the adding of dispersant, auto - propagating combustion and the condition in heat treatment of the gel on crystal phase, particle size, morphology and magnetic properties of bare ^ fe ^ o, ultrafine powders were firstly investigated systematically to clarify the optimum forming conditions
