%X 本研究对二氧化硫的制备及其部分性质的验证实验进行了改进设计&#65292;旨在实现实验装置的密闭性、操作的简易性以及实验现象的明显性。将此节课作为复习课进行&#65292;通过一个综合性的实验串联起二氧化硫的相关知识&#65292;引导学生在实验设计中巩固和应用知识。实验演示直观展示了知识&#65292;有助于学生对知识的理解和系统化。<br>In this study, the preparation of sulfur dioxide and its partial properties were designed to realize the airtightness of the experimental device, the ease of operation and the clarity of the experimental phenomena. This lesson is taken as a review lesson, connecting the relevant knowledge of sulfur dioxide through a comprehensive experiment to guide students to consolidate and apply the knowledge in the experimental design. The experimental demonstration intuitively shows the knowledge, which helps the students to understand and systematize the knowledge.
