摘要
导出了在位形空间中，求解对应无阻尼问题有等导重特征值的弱阻尼陀螺特征值问题的直接摄动法。算例表明本文所导出的方法是正确的。
The solution of eigenproblem of slightly damped gyro systems, of which the corresponding undamped system has repeated eigenvaluses with equal drivatives, are derived by the direct perturbation method in configuration space. The numerical examples show the validity of the method.
