c都整除d时,方程存在基础解时正整数a
c
d和非负整数m所有可能的取值。对每一个有基础解的方程,求解得出它的基础解,由这些基础解可以计算得到方程的多个整数解。
A class of Diophantine equation
ax
=m+dxyz
was considered. Based on the definition of the fundamental solution
with the help of the binary quadratic forms and the fundemental mathmatical knowledge
all of the possibilities of positive integers a
d and nonnegative integer m in the equation could be figured out when ald
bld and cld. And meanwhile
the corresponding fundamental solution was computed in each case. By these fundamental solutions
many integer solutions of every equation can be derived.
