| 摘 要： | 数形结合就是以数学问题的已知条件和结论之间的这种内在联系为依据，来分析它的代数意义，揭示它的几何意义，使数量关系和空间图形巧妙和谐地结合起来，并充分利用这种联系，非常恰当地改变问题或改变提问题的角度。数形结合往往能够起到化抽象为直观，化直观为精确，使许多复杂问题简单化、明了化，从而使问题得到解决。

| Abstract: | Based on the inner relations between the known condi-tions and the conclusions of mathematical problems, symbol-ic-graphic combination is to analyze the algebraic significance of the relations and reveal the geometric significance, so that the quantitative relations and spatial graphics are skillfully and har-moniously connected with each other, thus the problems or the angles of problems will be properly transformed by making full use of the relations. Symbolic-graphic combination can transform abstract problems into intuitive ones and then into accurate ones, making many complicated problems simple and clear, so as to solve the problems. |
