ICP-AES法测定硅钢中铌的不确定度评定
分析了电感耦合等离子体发射光谱法(ICP-AES)测定硅钢中铌的检测过程,讨论了该检测过程中不确定度的主要来源,建立了该方法的定量的数学模型,并根据这一模型计算出了检测结果的合成标准不确定度和扩展不确定度。 The measurement of niobium content in silicon steel by inductively coupled plasma atomic emission spectrometry(ICP-AES) was analyzed,by which the main factors affecting the uncertainty of the measurement were ascertained and the calculation formula was given.Finally,according to the formula the combined uncertainty and expanded uncertainty were obtained.
浅谈无底层取向电工钢的多种应用
介绍了国内无底层取向电工钢生产技术水平、产量和用途，简述了无底层取向电工钢作为取向电工钢超/极薄带母料及应用于制作大型发电机组铁心、风电等电机铁心和变压器铁心等的情况。 The production technology level,output and application of domestic glassless grainoriented electrical steel were introduced,and the application of glassless grain-oriented electrical steel as parent material of ultra-thin strip of grain-oriented electrical steel and in making large-scale electric generator cores,wind power motor cores and transformer cores were briefly described.
