To solve this problem,this paper analyzes the relationship between the number of slide pairs and success rate,proposes an improved method to the slide-algebraic attack 1.

To solve the problem, this paper establishes a mechanical model of casing bend to explain the relative slipping and casing bend mechanism for some layer segments.

For pile loaded on the head, treating deformation of pile elements, node displacements and node forces of the pile as intermediate variables, displacement equations of soil mass and equilibrium equation of pile-soil contact surface are established based on Mindlin equation and characters of relative slipping between pile and soil.

It avoided the relative sliding between the stock and the die and avoided needless reformation, and thus reduced the bending times.

This thesis analyzes the reasons in respect of theory, furthermore, it explains the effect that the relative sliding between the involate gears produces to the abrasion of the tooth surface.

The phenomena of the relative sliding between the slider and the linear bearing is analyzed.

This article deals with the influence, which is caused in gear transfering by different transfer rate from the point of the transfer force, relative slide speed and wear.

The effects of load and relative sliding linear velocity on the tribological behavior of the composites were investigated on a pin-on-disc test rig.

Taking the absolute slip coefficient of each spool of wet drawing machine as constant artificially with a progressive decrease from wire in to end product,and calculating the technological parameters for wet drawing with the constant absolute slip coefficient,which can reduce slip and prolong cone pulley life more than twice when applied to productio
