三边及面积均为整数的三角形称为海伦三角形，三边互素的海伦三角形，称为本原海伦三角形［１］．本文拟应用无平方因子数［２］的有关理论给出本原海伦数组公式．由于水平限制，不当之处，请同行指正．１　预备定理及公式定义１　ｅ∈Ｎ，如果ａ２｜ｅ，则ａ叫作ｅ的平方因子 Triangles with three sides and an area of ​​integers are called Helen triangles, Helen triangles with three sides and prime are called primitive Helen triangles [1]. This paper proposes to use the relevant theory without square factor [2] to give the original Helen array formula. Due to the level of restrictions, inappropriate, please peer correction. 1 Preparation Theorem and Formula Definition 1 e∈N, if a2|e, a is called the square factor of e
