Origin is the data analysis and draw software exploited by American company OriginLab, and also the advanced data analysis and drawing tool often used by researchers and engineers.
In the process of engineering, unstable situation such as floor heave happens a lot, so it is necessary to study the rheological features of mudstone.

Introduction Adding layer engineering can improve land use, reduce the cost of engineering, strengthen buildings and lengthen the useful life of old buildings.
But the load-bearing structure and foundation cannot support the big load of adding layer, it’s difficult for the users to move or the users cannot stop using the building during the adding layer engineering.
Profiles of the engineering of adding layer The project is a four-layer framework office building.

With the advantage of performance, electrostatic precipitator is applied in many different fields, not only in industrial: dust filter in coal, cement, thermal power, etc. but also in civil as kitchen smoke filter in restaurants.
