By comparing the displacement change of other monitoring points with the reference point,the deformation response ration was obtained to determine the stable status of different cut slope positions.

The rotational speed when the broken blade flings out,and the strain responses of the casing as the broken blade impacts on the casing are described in the paper.

The rotate speed of the released blade and the strain responses of casing are reported.

An adaptive simulation method for the design of array with frequency invariant response is proposed and is used to construct beamformer matrix to focus a wideband signal.

Introducing the concept of evolutionary frequency response, the evolutionary spectrum matrix of the random response under zero initial conditions of a time-invariant linear system subject to correlated evolutionary random excitations can be expressed in a concise way, similar to the matrix relationship between the power spectral densities of a stationary random response and the excitation.
