Influence of steady uniform currents on the simulation of storm surges

The market background for PCK to develop the UOE welded steel pipes is discussed, followed by a description of PCK's technological level exemplified by employing the UOE process to produce grade X70 pipes for the West-to-East gas transport pipeline, thus demonstrating the PCK's rising by development.

The "target tracing prospecting" method is favourable to collect two kinds of materials for two kinds of geochemical fields: background field and anomaly field in large-scale bedrock geochemical exploration.

Using background field method,derive the field equations for a flat Robertson-Walder background,and show that the scalar potential is a exponential function.

To the problem of the low precision of common magnetometers caused by the influence of the background magnetic field,a new fluxgate gradiometer which is based on the technique of the three-tip fluxgate and the structure-type of two sensors is developed.

And the illuminance control of the system was continuous in order to simulate stray light of the background of battlefield in almost all kinds of weather conditions.
