A new method relying on the Stroh formulism and the theory of the surface impedance tensor was developed to investigate the dynamic instability of interfacial slip waves.

The Stroh formalism and vectors analysis are applied to investigate the existence of slip waves propagating along the frictionless contact interface between two general piezoelectric solids.

The existence and propagation of a slip pulse at a smoothly contact separable interface between two anisotropic elastic half spaces is discussed in details based on the Stroh sextic formalism together with Fourier analysis and the singular integral equation technique.

6 jacket cap for drilling sufficiently and design a new slideway base on jacket BZ 25*.

Mechanic analysis was carried out to the slide condition of the vehicles at braked status, and brake of vehicles at different speeds as well as different braking effects due to different braking time were analyzed.

The article first introduces the slide problem that occurred for testing the friction drive capacity of traction wheel after the lift is installed, then analyzes reasons for the problem, and also puts forward a solution to solve the problem.
