给出一类三参数的四次 Thue 方程 $$x^4-4s{x}^{3}y-(2ab+4(a+b)s)x^2{y}^2-4absx{y}^3+a^2{b}^2{y}^4=1,s\ge 1,$$ 当 $a=2$, $b=1$时的所有整数解$(x,y)$.

In this paper, we give all integal solutions of a family of quartic Thue equations with three parameters \ay$$\begin{array}{r}{x}^4-4s{x}^{3}y-(2ab+4(a+b)s)x^2{y}^2-4absx{y}^3+a^2{b}^2{y}^4=1,\text{q}s\ge 1,\end{array}$$ when $a=2$, $b=1$.
