The effects of magnitude ofblade disorder and disk rotating speed on the vibrationmode localization are analyzed.
分析了叶片的失谐量和轮盘的转速对结构振动模态局部化的影响。

With the use of holography, the mode, amplitude and phase distribution of gas turbine bladevibration can be determined.
利用全息照相,我们可以得到燃气轮机叶片振动时的振型、振幅和相位分布。
