方程(?)(t)+p(t)(?)(t)+q(t)x(t)=0的一致稳定性

Uniform Stability of Equations (?)(t)+p(t)(?)(t)+q(t)x(t)=0

讨论二阶微分方程的一致稳定性,给出某些有用的判据。这些判据省去“q(t)>0”或“q(t)≥a>0”这类假设。

The uniform stability of the second order ordinary differential equations x (t) + p(t)x (t) + q(t)x(t) = 0 is discussed and some useful criteria are given. They omit the hypotheses 'q(t) > 0' or 'q(t) ≥α > 0' .
