热学的内容多而繁杂,笔者根据教学实践,以“二”为主线,梳理成以下8条辫子,以利于学生全面系统地复习热学知识.12种显微镜物体是由大量分子组成的.1)扫描隧道显微镜分子是很小的,分子之小,非肉眼和一般光学显微镜所能观察,回视所学知识,知道分子直径的数量级是10-10m,而扫描隧 The contents of thermal science are numerous and complicated. According to the teaching practice, the author uses the “two” as the main line and sorts out the following eight dice so as to facilitate the students to comprehensively and systematically review the knowledge of heat. The 12 types of microscope objects are composed of a large number of molecules. 1) Scanning Tunneling microscope molecules are very small, small molecules, can be observed by naked eyes and general optical microscopes, look back at what they know, know that the molecular diameter is of the order of 10-10 m, and the scanning tunnel
