Constraints on rupture speed of the 2001 M_S8.1 Western Kunlun Mountain Pass earthquake by co-seismic surface rupture slip displacements based on the slip-weakening mechanism with frictional undershoot involved;

The period of the pulse increases as the rise time increases,and the rupture velocity has great influence on the velocity pulse.

Based on our previous works on the fractal analysis of the turbulent flame with Reynold number from 4335-11100, a novel model of the propagating speed of turbulent flame was proposed here.

A comparative study on the propagation speed and physical parameters of underwater blast wave and air blast wave;

Solid Young s modulus is determined by measuring the propagation speed of longitudinal wave induced by ultrasonic wave in solid media.

characteristics of ultrasonic flaw - detection of iron castings, waveforms of average defects, and the relationships between transmission speed and nodularity as well as mechanical properties was introduced.

Using two sensors set at each side of a certain long oil pipe line,we can position the spilling point with the propagation time difference of the negative pressure wave caused by spillage,which can be more exactly when considering the relation between its propagation velocity and temperature in different mediums in this system.

Up till now there is no clear cut definition of theory for propagation velocity of coherent structure in wall region of a turbulent flow.

Based on experiment analysis of hydraulic properties of tidal bore about bore height、propagation velocity and tidal current velocity,the relative tidal bore height exceeds 0.
