摘要
本文应用李雅普诺夫一次近似理论，推导了单自由度体系及多自由度体系的非线性动力稳定判别准则。通过典型算例比较，该准则比Ｂ－Ｒ准则更加严密，适用范围也更加广泛。
Based on motion stability theory, the corresponding criteria of liapunov's stability for the SDOF and MDOF nonlinear systems are estabilished in the paper. Through analysis of a typical example, the criteria in the paper are more precise and could be used more widely than B-R criterion.
