圆形packing之计算总势能：总势能等于所有圆饼势能之和，而各圆饼的势能又等于该圆饼和圆盘以及其他圆饼之间的挤压挤压势能之和。挤压势能又等于他们之间的挤压深度的平方。所以可以通过分解问题使得复杂的问题简单化-The calculation of the total potential energy circle packing: the total potential energy potential energy is equal to the sum of all the pie, and each pie is equal to the potential energy and the round cake and pie disk, and other potential energy between the squeeze and squeeze. Potential squeeze squeeze between them and the depth equal to the square. Decomposition made it through the simplification of complex issues
