空间向量是高中数学立体几何中新增加的内容 .借助于空间向量工具 ,可以对一些传统解法中较为繁琐的问题加以定量化 ,从而降低了思维难度 ,增强了可操作性 ,使学生对立体几何更容易产生兴趣 .空间向量在角和距离的处理上有着独特的优势 ,它最大限度地避开了思维的高强度转换 , Space vector is a new addition to the mathematics of high school mathematics. With the help of the space vector tool, it can quantify some of the more tedious problems in traditional solutions, which reduces the difficulty of thinking, enhances operability, and enables students to have a solid geometry. It is easier to generate interest. The space vector has unique advantages in the processing of angles and distances. It avoids the high-intensity transformation of thinking to the maximum extent.
