事物是错综复杂的,但却是有序的,总可以按照某种对应关系,找出它们间的联系,找准各自的位置;而在数学解题中,如能找准量与量间的对应关系并合理利用它,就如同抓住了问题间联系的纽带,能够使解题的线索迅速明朗,解题的思路更加清晰.可以这样说,对应关系在数学解题中的作用不可小 Things are complex, but it is orderly, always in accordance with some correspondence, to find out the relationship between them, identify their own position; and mathematical problems, such as to find out the correspondence between quantity and quantity Relationship and rational use of it, just as to seize the link between the problems of the link, can make the clues to solve problems quickly clear, the problem-solving ideas clearer .That can be said that the corresponding relationship in the mathematical problem solving role is not small
