摘要 利用同余、Legendre符号、Pell方程的解的性质等证明了椭圆曲线y^(2)=x^(3)+21x+148与y^(2)=x^(3)+21x-148无正整数点. In this paper,by using the congruence,Legendre symbol,and the properties of the solution of the Pell equation,the elliptic curves of y^(2)=x^(3)+21x+148 andy^(2)=x^(3)+21x-148 were proved that there were no positive integer points on the curves.
