At first, geometric mean model can be applied to calculate the effective thermal conductivities for unsaturated and saturated soil around the GHE, which can guarantee the results between lower and upper bound; then consider unsaturated and saturated soil as single-phase materials, as the arrangement is parallel to the direction of heat flux, parallel model can be applied to calculate the overall effective soil thermal conductivity.
For saturated soil, the pore space is filled with liquid phase material.

As a primary
raw material - some kinds of strip steel are used by some important industries, such as military
affairs, aviation and spaceflight, shipbuilding industry; it also has been used extensively in many
other fields of people living product, for example, automotive and electronics industries and so on.
When received indent, enterprises make material quality plan by material requirements of consumer, including quality standard of product surface, bringing forward different process criterion, prescribing different parameter of production control and demand of performance detection.
Because of the steel enterprise's ever-present defects and defect rang of our lab system of defects inspection on-line to inspect defects, there are ten kinds of defects confirmed to assessing grade, including Scratch Strip (Fig.1), Holes (Fig.2), Roll Marks (Fig.3), Pits (Fig.4), Mixed Material (Fig.5), Blisters (Fig.6), Shell, Extraneous Matter Roll-in, Crack, Scabs.
But because defects of "Holes, Crack, Mixed Material, Blisters" influence product use badly, they are defined as key defects.

As the
versatility of Rykalin series mathematical models, carbon steel, stainless steel, titanium and other
different metal materials' welding heat cycle curve can adopt these methods, the methods have
great practicality
As for thin-sheet material, we could choose Hannerz, Rykalin2-D, Rosenthal mathematical model.
While the thick-sheet material, we should choose Rykalin3-D mathematical model.

Traditional river side-slope protection technologies are tend to emphasize the river flood control, water diversion, drainage, water storage, shipping, etc., so the side-slope protecting works are usually constructed by use of rigid hard materials such as slurry masonry or concrete.
Therefore, neither of the methods (that is, to use rigid material or decrease slope coefficient) is ideal.
Therefore, the eco-engineering measures which take plant as main engineering material have a good application prospect.
Materials and Methods Basic Situation of Experimental Rivers.

Introduction
Laser direct metal deposition (DMD) is more and more envisaged for rapid freeform fabrication of fully dense or controlled porosity metallic materials, directly starting from computer-aided design drawings.
Additional investigations on 316L stainless steel have also been carried out to identify the material contribution.
A helicoïdal powder nozzle was used, where the powder material (45 µm -75 µm average grain size) is delivered coaxially with the laser beam, resulting in a dp ≈ 2 mm powder focus diameter, and with average mass feed rates Dm in the 1 g/min to 3 g/min regime.
Future investigations will consider systematically the correspondence between melt-pool volumes and aspect ratios, and resulting surface topographies, on Ti6Al4V and 316L steel, in order to (1) propose a material-dependent phenomenological model, and, in a second step (2) to be able to predict analytically surface finish.
