按照传统方法求空间距离,往往要通过各种手段进行转化,且具有较大灵活性．而以向量为工具求空间距离,可避开纷繁复杂的推理,使解法固定,过程顺畅、简捷．
Finding the spatial distance according to the traditional method often requires transformation through various means and has greater flexibility. The use of vector as a tool to seek spatial distance can avoid complex and complicated reasoning, make the solution fixed, and the process is smooth and simple.
