就结式在判定方程是否有重根 ,判断两个多项式是否有公根 ,在参数方程中消参这几个方面的应用 。
In this paper, the author has illuminated the instruction of one of advanced mathematics -applications of the eliminant in equation, such as the application of the eliminant in determining that whether or not the roots of equation are poly-root, the application of the eliminant in determining that whether or not two polynomials has the same root and the application of the eliminant in eliminating parameter in parameter equation.
