方程x(t)+ax(t)+bx(t-τ)=0渐近稳定性代数判据的新证明(Ⅱ)

NEW PROUEMENT OF EQUATION x(t)+ax(t)+bx(t-r)=0 ASYMPTOTIC STABILITY ALGEBRAIC CRITERION

在文［４］的基础上，采用新方法重新获得了滞后型方程ｘ（ｔ）＋ａｘ（ｔ）＋ｂｘ（ｔ－τ）＝０（Ｅ）零解渐近稳定充要条件的代数判据。（其中ａ，ｂ为任意常数，τ为正常数。）

Based on paper [4], hysteresis equation: x(t) +ax(t) +bx(t-r) =0(E), zero solution's asymptotic stable sufficient and necessary conditional algebraic criterion was obtained again by adopting a new method. (a, b, are arbitrary constants, is normal number.)
