| 摘 要： | 数学中存在着大量的成对的最大值命题和最小值命题.容易发问,这些命题总是同时为真(或同时为假)的吗?文章对这些成对的命题作一个初步概括,随后给出一反例,表示它们并不总是同时为真.文章籍图象揭示这些成对命题的内在联系,导出一个充分判别法并给出严谨的逻辑论证.文末,从实用角度作出相应结论.

| Abstract: | There are lots of double of proposition of Largest and Least value in mathematics.Are the propositions true(or false)in the same time?This article explains and gives an opposite example to prove that they are not true in the same time and not false in the same time too.According to the graphs,the article presents the interrelationship of the double proposition to introduce the method of sufficient evaluation which was logically discussed.In the end of the article the conclusion is given by the practical way. |
