摘　　要：自制实验装置在培养本科生创新意识、提升学生实践能力、促进教师教学效果等方面有着积极作用,是高校教学改革的重要手段。通过对含惰性气体保护的雾化装置和产物静电集尘收集器两个部分的创新设计,设计和制造出雾化液滴自蔓延燃烧合成纳米粉末的装置,并在教学和科研中运用和实践。实践表明:该实验装置对本科生创新意识和实践能力的培养发挥了较大作用,有助于促进教师教学效果,适合学生开展纳米材料制备的创新性研究,符合高校对促进本科教学、提升科研水平的实际需求。Self-made experimental device plays an active role in cultivating innovative consciousness and improving practical ability of undergraduates,promoting teaching effect of teachers and the like. It is also an important means for implementing reform in education of colleges and universities. Through the innovative design of atomization device with inertia gas protection and product electrostatic dust collector,a device for synthesizing nano-powder by self-propagating combustion of atomized droplets was designed and manufactured,which was applied and practiced in teaching and scientific research. The practical results show that the experimental device plays an important role in the cultivation of undergraduates’ innovative consciousness and practical ability,which is helpful to promote the teaching effect of teachers,and is also suitable for students to carry out innovative research on the preparation of nano-materials,and meets the actual needs of colleges and universities to promote undergraduate teaching and improve the level of scientific research.
