岩心核磁共振仪在本科实验教学中的应用

Application of Core Nuclear Magnetic Resonance Apparatus in Undergraduate Experiment Teaching

  • 摘要: 为帮助应用地球物理专业的本科生掌握岩心核磁共振仪的原理和使用方法,以及提高实验教学效果,该文讲述了岩心核磁共振仪的原理、技术参数、参数调节和功能,并利用该仪器在本科生课程中设计了岩样核磁共振测量实验,另外,开发了两个开放创新实验。这些实验,是理论教学很好的补充。通过这些实验,学生巩固了核磁共振和弛豫时间的概念,了解了岩样横向弛豫时间T2和纵向弛豫时间T1的测量方法,培养了学生动手和科学探究能力,提高了学生科学素养。该仪器在教学中发挥出不可替代的作用,在有类似仪器的高校中可以推广应用。

     

    Abstract: In order to help undergraduates majored in applied geophysics master the principle and application method of core nuclear magnetic resonance apparatus and improve the experimental teaching effect, this paper has described the principle, technical parameters, parameter adjustment and function of core nuclear magnetic resonance apparatus, at the same time designed an experiment of core sample nuclear magnetic resonancemeasurement in the undergraduate course. Furthermore, two open innovation experiments are developed, which are a good complement to theoretical teaching. These experiments have enabled the students to consolidate the concept of nuclear magnetic resonance and relaxation time, and acquire the measurement methods of transverse relaxation time T2 and longitudinal relaxation time T1 of core samples. Therefore, not only their practical and scientific inquiry abilities are cultivated, but also the scientific literacy is improved. In a word, the apparatus plays an irreplaceable role in teaching and can be popularized and applied in universities with similar apparatus.
