Materials and Methods The chemical composition (in weight percent) of molten steel is 0.005% C, 3.0% Si, 0.07% Mn, 0.028% S and the remaining is Fe.
The key to calculating the molten steel level is to determine the upper surface area of the molten pool by calculating the partial area of the upper surface of the molten pool within the ROI.

Accordingly, it showed that inorganic minerals and organic materials could affect the mobility and bioavailability of heavy metals.
Materials and Methods Soils.
Biochar produced under the high temperature had big specific surface area, mainly on account for oxygen element bagasse (raw material of biochar) contained.

Gas cluster ion beam technology for nano-fabrication Noriaki Toyoda and Isao Yamada Graduate school of engineering, University of Hyogo 2167 Shosha, Himeji, Hyogo, 671-2280, Japan ntoyoda@incub.u-hyogo.ac.jp Keywords: Gas cluster ion beam, nanofabrication, surface planarization, sidewall roughness Abstract A gas cluster is an aggregate of a few to several thousands of gaseous atoms or molecules, and it can be accelerated to a desired energy after ionization.
Ion beam process is one of the key technologies in nano-fabrications such as etching, thin-film formation, or implantation of impurities.
After etching the magnetic layer, these patterns were refilled with a film of TiCr which is a nonmagnetic material, by sputter deposition (Fig.6 (c)).

., coal, ore, crude oil, groundwater, natural gas, etc), underground engineering in the urban area and displacement of earth crust are major factors that can cause surface deformation and uneven settlement.
Material operation(without swing column, it participates in the former three deformation only): The base of swing column (if it has swing column) which simulate earth surface deformation are fixed;1)the base of the left column and right column exert displacement towards right and left respectively, to simulate ground compression deformation; 2)the base of the left column and right column exert displacement towards left and right respectively, to simulate ground stretching deformation; 3)the base of the left column and right column exert displacement towards downwards and upwards gradually, to simulate ground tilt deformation; 4)the base of the left column and right column exert displacement towards upwards gradually, to simulate ground positive curvature deformation; 5)the base of the left column and right column exert displacement towards downwards gradually, to simulate ground negative curvature deformation.
