摘要
结合地质大学的专业特色,介绍了对显微镜组装实验的改进,结合偏振光的知识,设计组装了正交偏光显微镜。以橄榄岩、石英、玻璃、电气石为样本进行了观察。改进后的实验激发了学生的学习兴趣,并为学生将来的专业课学习打下了基础。
According to the features of the majors at University of Geosciences, the authors introduce the improvement of the microscope assembly experiment. Combining the knowledge of polarized light, we design the orthogonal polarizing microscope, and then observe the peridotite, quartz, glass and tourmaline samples. The improved experiment not only stimulates students＇interest in learning, hut also lies a foundation for the students＇future courses learning.
