图像可以直观地表达多个物理量间的相互关系以及变化趋势,高考中通常以作图题的形式来考查学生对知识的理解和掌握程度。本文以一道化学作图题为例,尝试用Excel中强大的计算和画图功能对化学作图题进行案例式探析和研究。
The image can intuitively express the interrelationship between different physical quantities and the trend of change. The college entrance examination usually examines students’ understanding and mastery of knowledge in the form of drawing questions. In this paper, we take a chemical mapping problem as an example, try to use the powerful calculation and drawing function in Excel to do a case study and research on chemical mapping problems.
