该文遵循循序逐增原理,从对边形数、棱锥体数以及其点与点之间连线形成的三角形的量的循序逐增现象研究中,求得其循序逐增规律。应用拓扑原理,可将边形数置换为扇形图表达,将棱锥体数置换为圆形图表达,发现了棱锥体数与边形数之间的相近相同规律。 According to the principle of sequential increasing, the law of sequential increasing is obtained from the research of sequential increasing of the number of the triangle, the number of pyramids and the connection between the point and the point. Applying the principle of topology, the number of sides can be replaced by the representation of sector, and the number of pyramids can be replaced by the diagram of circle, and the same regularities between the number of pyramids and the number of sides have been found.
