摘　　要：在稳定约束情况下,拉格朗日方程可以给出能量积分;在非稳定约束情况下,约束反力可以作功,因此即使是在保守力场的情况下拉格朗方程也并不一定给出能量积分,只能给出与能量积分相类似的广义能量积分。Under the circumstances of stable bounds, Lagrange' s equation can give energy integral, but under thecircumstances of unstable bounds, the inverse binding force may work, therefore, even in the conservative field of force,Lagrange s equation may not give energy integral but just give generalized energy integral which is similar to energyintegral.

关 键 词：非稳定约束 二次非齐次函数 广义能量
