Atomic form factor

In this paper,we firstly modified the mistake in reference of Bennett,then using Strmer s theorem of the solutions of Pell equation,and a deep result of privitive divisor of Bilu,Hanrot and Voutier,we proved that there is no exist four distinct triangular numbers in geometric progression,therefore we sovled the question of Sierpinski on triangular numbers.

基于三角數問題的研究目前非?；钴S,最近,Bennett宣布解決了由Sierpinski提出的一個三角數猜想問題,本文指出了Bennett文中的錯誤,并利用Pell方程解的性質的St rmer定理以及Bilu,Hanrot和Voutier的關于本原素因子的深刻結論,證明了在一列幾何級數中,不存在4個相異的三角數,完整地解決了Sierpinski的問題。
