We revisit Darboux' parametrization of the configuration space of a quadrilateral with fixed side lengths by elliptic functions, remind how it implies Darboux' folding porism, and relate it to Bottema's zigzag porism. Further, we review some mechanical applications of this parametrization giving rise to overconstrained linkages and polyhedra.

四连杆,椭圆功能和柔性多面体

我们通过椭圆函数重新讨论了Darboux对具有固定边长的四边形的构型空间的参数化,提醒它如何暗示Darboux的折叠多孔性,并将其与Bottema的之字形多孔性联系起来。此外,我们回顾了这种参数化的一些机械应用,这些应用导致了过度约束的连接和多面体。
