平板折叠桌结构简单，造型美观，通过桌腿的翻转形成美丽的直纹曲面。本算法旨在通过稳固性，加工方便，用料最少三个方面建立数学模型，得出平板桌设计的最优方案。(The plate folding table has simple structure and beautiful shape, and forms beautiful straight surface through the flip of the table leg. This algorithm aims at stability, easy processing, material at least three aspects of the establishment of mathematical model, the optimal scheme of flat table design.)
