摘要
研究了二阶变系数齐次线性方程组可化为某些可解方程组的问题,应用变量代换法得到了三个可化为可解方程组的充分必要条件.
The questions for transforming system of second order variable coefficient homogeneous linear ordinary differential equations into some solvable system of equations are discussed, three necessary and sufficient conditions for transforming system of variable coefficient equations into solvable system of equations are given, which are the aid of change of a variable.
