数学以客观世界中的空间形式与数量关系为研究对象，数形结合思想是数学中非常重要的思想和解决问题的常用策略，正如华罗庚所指出的“数与形本是相倚依，怎能分作两边飞，数缺形时少直观，形少数时难入微”．美国数学家斯蒂恩说：“如果一个特定的问题可以转化为一个图形... Mathematics is based on the relationship between spatial form and quantity in the objective world. The combination of number and shape is a very important idea in mathematics and a common strategy for solving problems. Just as Hua Luogeng pointed out, “Number and shape are dependent on each other, how can we Divided into two sides to fly, when the number of missing is less intuitive, when a few are difficult to understand.“ American mathematician Steen said: ”If a particular problem can be transformed into a graphic...
