small disturbance method

Calculation of the complete transonic unsteady small disturbance equation by ADI method

ADI方法求解完全跨声速非定常小扰动方程

The results show that the method based on BWD spectral kurtosis can effectively extract disturbance characteristics and has a good anti-noise capability; SVM classifier can effectively identify two kinds of disturbance and has a higher recognition rate for small samples and other disturbances superposition.

结果表明，基于BWD谱峭度方法能够有效提取扰动特征量，且具有良好的抗噪性能；利用SVM分类器在小样本和叠加有其他扰动时，有效识别两类扰动，识别率较高。

Therefore, effective isolation method is investigated by combining active and passive vibration isolation technology for out small disturbance.

为此，结合主动隔振和被动隔振技术研究对外界微小振动扰动有效隔离方法。
