Lumbar motor unit instability caused by the scope of nociceptive related to the soft tissue both inside and outside spinal canal and instability junction,so the scope of treatment should take into account the multi-faceted three-dimensional.

Fold catastrophe model of rock dynamic destabilization

Those mainly related to the mechanical properties and its deterioration in EDZ,non-stable subsidence of roof rocks and horizontal squeezing and its coupling effect so as to destabilization,delamination upon deepening rocks at roof induced to the localized dynamic destabilization.

4 centrifugal compressor of Chinese Aluminum Manufacturer Shanxi Branch, this paper provides the distinctions of the methods for diagnosing and Identifying the dynamic destabilization of the seal-gap and the oil-film vibration of the centrifugal compressor, and identifies that the two sides are connected with each other and promoted each other.

Quantitative prediction and comprehensive evaluation on dynamic destabilization of LSMA due to excavation disturbance underneath river;

Role of tip leakage flow on flow instability and its control with circumferential groove casing treatment;

Research on flow instability of transonic compressor rotor and boundary suction effect at low Reynolds number

Research on flow instability triggering process at stall condition of transonic compressor rotor at low Reynolds number

Difference solution to dynamic instability of straight bars under elastic compression wave;

Based on the generalized variational principle of ferromagnetic bodies and the technique of magnetic field perturbation,this paper present an analysis on dynamic response and dynamic instability of the ferromagnetic beam-plate with unmovable simple supports under the two type pulse magnetic fields.

In the test, both the local dynamic instability for shell members and the global dynamic instability of the structure were observed.
