Abstract: The paper discusses the changes of vibration systems with close frequencies.As the system parameters are changed,the relation of systems between close frequencies and repeated frequencies is formed.A simple and efficient sensitivity formula based on perturbation method for near defective systems is presented.

Key words: sensitivity, near defective system, matrix perturbation
