空间向量是解决数学问题的有力工具

The Apple cation of Spacial Sectors

向量具有一套完整的运算性质。利用这些性质对题目进行分析转化、联想、构造、解题途径便有规律可循。学生在解题时就游刃有余 ,轻松自如。同时空间向量的引入对高一层次的基础教育起到了衔接作用。总之 ,空间向量的引进 ,对中学数学无论在理论上还是实践上都具有重要意义。

Sectors have a set of complete characteristics for number operation,by which the laws of problem solving can be found through analying,transforming,associating and constracting the subject.The introduction of spacial sector has important meaning to mathematics in middle schools both theoretically and practically.
