立体几何中动点轨迹问题的探求,主要是转化为平面几何问题,再利用平面几何、解析几何和空间向量等知识来求解,以下就典型的轨迹模型予以剖析.
The search of the trajectory of moving point in solid geometry is mainly transformed into the problem of plane geometry, and then solved by the knowledge of plane geometry, analytic geometry and space vector. The typical trajectory model is analyzed below.
