| 摘 要： | 设n,a,b,c是正整数,gcd(a,b,c)=1,a,b≥3,且丢番图方程a~x+b~y=c~z只有正整数解(x,y,z)=(1,1,1).证明了若(x,y,z)是丢番图方程(an)~x+(bn)~y=(cn)~z的正整数解且(x,y,z)≠(1,1,1),则yzz或xzy.还证明了当(a,b,c)=(3,5,8),(5,8,13),(8,13,21),(13,21,34)时,丢番图方程(an)~x+(bn)~y=(cn)~z只有正整数解(x,y,z)=(1,1,1).

| Abstract: | Let $n,a,b,c$ be positive integers with $\gcd(a,b,c)=1,\ a,b\geqslant 3$
and the Diophantine equation $a^{x}+b^{y}=c^{z}$ has only the positive
integer solution $(x,y,z)=(1,1,1)$. In this paper, the authors prove that if
$(x,y,z)$ is a positive integer solution of the Diophantine equation
$(an)^{x}+(bn)^{y}=(cn)^{z}$ with $(x,y,z)\neq (1,1,1)$, then $y
