关于带参数五次代数方程判别根的一个充要条件

ON A NECESSARY AND SUFFICIENT CONDION OF DISCRIMINATING ZEROS OF ALGEBRA EQUITIONS OF ORDER FIVE

本文给出了带参数五次代数方程f(x)=x^5+a_1x^4+a_2x^3+a_3x^2+a_4x+a_5=0有一对纯虚根且剩余根均具有负实部的一个充要条件。

in this paper. We gave a necessary and sufficient condion of the algebraic equa- tion of order five Which has a pair of pure imaginary zeros and the other zeros have negative rtal ports.
