Two-dimensional heat transfer model for round billet continuous casting was established by Shuigen Wang [4] which provided a theoretical basis for the caster structure design and cooling system optimize, meanwhile, improved the efficiency of the casting machine and the round billet quality.
(3) Wherein ,is the beam blank surface temperature in K； is environment temperature in K.is dimensionless coefficient, can be carried out by the Nailing experiments. 3) Water evaporation heat transfer Some of cooling water sprayed onto the beam blank surface don’t evaporizes immediately, so the part of water deposited in the inner radius surface, but the part of water in the outer radius will drop down form the surface by the gravity due to the arc structure of the caster machine.

According to the theory of colloidal structure we know that the effect of the thickness of water-membrane, the degree of superposition of water-membranes, or the distance between particles on the plasticity of body.
The major mineral composition in Guilin clay is sericite, the structure of sericite and illite is similar, and its plasticity is similar to Longyan clay and Tangxian clay.
Summary According to the theory of colloidal chemistry, the determining parameters of plasticity have relations of summation in actual body by the determination of reasonable evaluation method of plasticity index II.

In a stable system, settling of the single particles is slow, and close sediment structure is formed, the sediment volume is small.
While in the unstable and flocculated system, settling of particles is rapid, and the sediment has loose structure [18].

On the other hand, with the potentiodynamic technique, the polymerization is localized only on the active sites of the working electrode surface and the polymer presents a cauliflower-like morphological structure (Fig. 3b).
The results obtained with these spectroscopic techniques confirm that the PT electrochemically synthesized on these oxidizable metals has globally the same vibrational structure and elementary composition as those obtained classically on noble materials.

The magnetic powder had promoting effect on the growth of microorganisms and the activity of dehydrogenase, and had the effect of flocculation making the tight structure of the sludge, so after a period of shocking, the treatment efficiency of reactor with magnetic powder was better than that of reactor without magnetic powder.
While the structure of sludge in the reactor without magnetic powder was poor and loose, only few acid-forming bacteria could exist, so pH decreased slightly.
