摘要
所有关于椅子放稳问题的论述,都是通过旋转椅子建立的数学模型,然后对模型进行求解.指出这种建模方法所存在的缺陷,即建立的模型与假设条件相矛盾,并提出改进的方法.
All the discussions about the steadily-placed chair problems are made through the mathematical model of a rotated chair and its solutions. This present study is to make a conclusion that the method of the proof is incorrect, and that is, there exist contradictions between the established model and the assumptions. A new solution is showed in the paper.
