今年三、四月份,保加利亚高等地质及矿业学院副教授K·阿基诺夫(Anguelov)应邀来长春地院讲学。讲学的内容有三部分,第一部分为粘性土的微观结构及其成分。在这一部分他重点讲述了四个问题:粘性土成分;结构的研究方法;结构基本单元和结构连结;粘性土微观结构类型和粘土质岩的分类。 关于成分、结构研究方法,他介绍了目前世界上所使用的各种方法,并着重介绍了电子显微镜、x光衍射、热分析等方法在粘性土成分结构研究中的应用和有关注意事项。例如,电镜样品的制备,用 In March and April this year, Anguelov, an associate professor at the Higher Institute of Geology and Mineralogy of Bulgaria, was invited to give lectures in Changchun. The content of lectures has three parts, the first part is the microstructure of clay and its components. In this section, he focuses on four issues: clay composition; structural research methods; structural basic units and structural links; the classification of clay microstructures and clay rocks. On the composition and structure research methods, he introduced various methods used in the world, and introduced the application of electron microscopy, x-ray diffraction and thermal analysis methods in the study of the composition of clay and the related considerations. For example, electron microscopy sample preparation
