This paper made a deep research on the static and dynamic load testing technology of simple support reinforced concrete beam bridge,and the principle,process and data analysis method of static parameters and dynamic parameters testing.

It explained certain way of dynamical Poisson s ratio and found the approach of dynamical parameter (especial dynamical shear module) by static parameter vibration parameter of soil body.

The read only parameter list is also called static parameter list.

A theoretical calculation method for flow rate coefficient and hydraulic parameters of conical nozzle;

The Influence of the Change of Drill Bit Hydraulic Parameter on the Drilling Effect in CCSD Pre-Pilot Hole Drilling Project;

The theoretical models for hydraulic parameters of fluidics downhole boost compressor were set up with the fluid mechanics network method on the basis of structure and work principle of the first generation of downhole boost compressor.
