By using the equations of mass conservation law and Navier-Stokes, as well as applying 3D numerical calculation about spiral continuous casting mould, and computer simulation the fluid flow in spiral continuous casting mould was studied including the effects of the fluid field under the different parameters (casting speed, rotational speed, immersion depth).

Analysis on ladle nozzle blockage in casting Ca-treated liquid steel and Process improvement;

Current research status of tundish nozzle clogging;

Practice of reducing tundish nozzle clogging;

Study on mechanism of nozzle clogging in slab continuous casting of liquid steel refined by CAS-OB;

At last,the study of nozzle clogging is presented from the dynamics viewpoint.

The best way to prevent nozzle clogging is to optimize caster operating parametres and Catrealment.

Fractal Character of Element Distribution in Shuikoushan Pb-Zn-Au Polymetallic Ore Field;

Geological characteristics of silicified Breccia in Shuikoushan lead zinc polymetallic ore field of Hunan and its association with mineralization;

Geochemical characteristics of the Shuikoushan Pb-Zn-Au-Ag deposit,Hunan;

The water and mathematical modeling was carried out to study the flow field using swirling flow nozzle in continuous casting billet mould,the influent of the angle and location of the blade on flow pattern inside the mould was analyzed.

Optimization on stilling basin for outfall of power plant;

Analysis of the layout of water intake and outfall in Shajiao Power Station;

Based on the results of water quality(physical and chemical factors:water temperature,salinity,pH,DO,DIN,PO4——P,COD,and biomarker-indicated:total bacteria and Coliforms) determining from the 4 pools and infall,outfall of the Xishan Island aquaculture pond,the variation characteristics of water quality in infall,outfall of pond and its reasons were analysised and discussed.
