However, the light energy utilization rate of sandblasting reflective materials is low, the surface spraying of sand grain presents a state of the unordered arrangement, which leads dead angle, and loses some or all of the light energy after multiple reflections in the sand.
It shown that the volume on the surface of the microstructure increased when the height of the microstructure became bigger with the same radius from figure (a), and the angle of their normal migration became bigger, so the light after reflection was more tend to round out, then the reflection properties increased. when the height of the microstructure remains unchanged, as shown in figure 5 (b), as the radius increased gradually, the number of microstructure can be arranged in the material surface was less, so the reflection properties would decrease; In addition, the light on the surface microstructure of normal direction draw closer with the increase of the radius to local normals of microstructure, material reflection performance was relatively lower.

Hereby, the rails are subjected to larger number of repetitions of cyclic loads, which would lead to faster and more frequent occurrence of wear and fatigue defects and resulting severe accident [2].

With more than 10 kinds of colors, the stone chips are composed of a certain grain of basalt particle by high-tech coloring process and high temperature sintering.
For the camouflage coating on the steel sheet, because the color number is more than two, the key scheme is to control the feeding speed and to keep the sum of the stone chips amount as a constant all the time in the coating process.

With the annealing temperature increasing, diffusion of aluminum and copper atoms are enhanced, the growth of intermetallic compounds will be accelerated, which results in the formation of large numbers of intermetallic compounds.
The lower activation energy of CuAl2 is generally considered as the indication of the formation of intermetallic compound by short-circuit diffusion via structural defects such as grain boundary and/or dislocation commonly found in tetragonal structure.

., The less number of probes, the characteristics is more nearly to parallel lines.

In addition, light scattering occurred around the grain boundary of the ZnS:Ag powders, and the incident ions were deflected away as they were getting into the sample.
The number of incident ions was counted using a silicon charged particle detector after the sample irradiation.

In this way, with a minimum number of processing steps and good economic indicators, a profile is obtained from chips - a circle, a corner and more complex forms that can be used in areas of technology that require low-density materials and average strength indices (400-500 MPa).
This is due to the melting of low-melting eutectic components along the grain boundaries [6].

From the analysis of the micrographs of the powders shown in Fig. 1, one can see that the particles have a predominantly regular spherical shape; however, there are a small number of satellites and granules that have an irregular shape.
Diffraction patterns of X6CrNiTi18-10 electric arc remelting steel: original workpiece (1) and manufactured powders: grain size - 120-63 μm (2), 63-20 μm (3) and 20-0 μm (4).

SLS uses fine powder spread by a re-coater on the machine bed and scanned directly by a CO2 laser such that the surface tension of the grains is overcome, and they are sintered together.
Since the current study was limited to two parameters, it is recommended that future studies increase the number to obtain a more accurate result.

The concrete cover layer with thickness of only 1 mm required the use of high-performance fine-grained concrete mixture.
The load-bearing capacity of the anchoring elements is essential for the design of their number and placement.
