| 摘 要： | 在凸凹不平的地面上，很难一次将四条腿桌子放稳，但在任何位置，四条腿桌子至少有三条腿着地，然而将四条腿桌子旋转调整几次，就可以使其放稳。本文先就桌子四脚的连线呈正方形的情形建立了数学模型，然后再推广到桌子四脚连线呈长方形的情形，并给出了模型解释。

| Abstract: | It's very difficult to make a table with four legs steady only once on the uneven ground,but at least three legs can touch the ground in any places in case the table has four legs.However,it can be steady in case the table with four legs is revolved and adjusted several times.In this paper the connected lines of the four feet of the table can be in the form of square to build a model of math as well as the form of rectangle,giving explanation of the model. |
