论文摘要
如果其触点图是三角剖分，则平面中的圆盘堆积是紧凑的。 $ 9 $ r $的$ 9 $值使光盘的紧凑型填充Radii $ 1 $和$ r $。我们证明，对于这些$ 9 $的每个值，对于紧凑型包装，达到了Radii $ 1 $ 1 $和$ R $的所有包装上的最大密度（我们给出它及其密度）。
A disc packing in the plane is compact if its contact graph is a triangulation. There are $9$ values of $r$ such that a compact packing by discs of radii $1$ and $r$ exists. We prove, for each of these $9$ values, that the maximal density over all the packings by discs of radii $1$ and $r$ is reached for a compact packing (we give it as well as its density).
