文[1]给出欧拉不等式与边长间的一个不等式链,笔者得到欧拉不等式的一个三角形式的加强链,与不等式爱好者共赏.定理设R,r分别为△ABC的外接圆及内
In [1], an inequality chain between Euler inequality and side length is given. The author obtains a triangular chain of Euler inequality, which is shared with the inequality lover. Theorem Let R and r be the circumcircle of △ ABC And inside
