forces, surface roughness
Abstract.
As a promising processing technique of hard and brittle materials, ultrasonic assisted grinding (UAG) can not only enhance the machining efficiency but also improve the surface quality [4].
Once a wheel depth of cut ap is given to the workpiece and a feed motion is provided to the worktable at a rate of Vw with a stroke of S, the grinding wheel rotating at a speed of Vs will interfere with the workpiece to remove the work-materials.
However, it should be noted that in the first two regions the ratio in EUAG is much less than that in CG, indicating that it is easier to remove the work-materials in EUAG than that in CG.

These studies use construction materials with standardized properties.
It presents a comparison between two families of beams (small beams and normal beams) out of BA with same materials what makes it possible to study the scale effect.
Other studies, Japanese women, [10] on brick walls confined by columns and beams out of reinforced concrete were made with the échelle1/2 by using the same properties as materials available in the building sites.
As the composite being integrated in the matrix, the physical interface with concrete still remains permanent and the adherence between the two materials is perfect.

The failure of the whole honeycomb sandwich composites are judged by the failure criteria of constituent materials.
Then the stresses in the constitutent fiber and resin materials can be determined through the bridging matrix, ,
Due to the same reason, the ultimate load predicted by this paper is 17.3% higher than testing results which is acceptable in engineering.

At the same time, it must be focus on the technological transformation and pollution control of the six sectors of the food, petrochemical, metallurgy, building materials, textile, and nonferrous metallurgy.
During architectural design, it is important to encourage the adoption of a new structural system, new wall materials and renewable energy.
It should introduce the low-carbon concept from the full use of solar energy, the choice of thermal insulation building materials, the rational design of ventilation and lighting systems, the choice of energy-efficient heating and cooling systems, etc.
During architectural operation, it is important to advocate the construction of low-carbon decoration and selection of low-carbon decorative materials to avoid excessive decoration.
One is to use crop straw resources as feed, fertilizer or training materials.

Membrane materials with a predominance of the thermodynamic component of transport cope well with the selective transfer of VOCs.
These materials have gained their widespread use due to their high permeability and stability of transport characteristics over time.
Therefore, they find real industrial application as materials for separating membranes [6].
Each subsequent application brings the selectivity of the composite membrane closer to the selectivity of the membrane material.

Abstract.
The commercially used membrane materials include ceramics and both unmodified and surface modified polymeric materials, such as polyethylene, polypropylene and polysulfone [11].
However, the high cost of membrane materials limits its further applications.
Polypropylene (PP) non-woven fabric (NWF) materials are composed of random network of overlapping fibers.
It shows that the cake resistance is the key part in fouling resistance when the operation is stable, which consists with Lim’s study.

The trabecular bending test is designed to determine asphalt mixture material properties (LMT~3).
Fatigue numbers refer to loading times during the period when the material stiffness modulus reaches 50% of the original stiffness modulus.
Experimental operation is strictly subject to the Standard Test Methods of Bitumen and Bituminous Mixtures for Highway Engineering (JTJ052-2000) of China.
When conducting freeze-thaw split tests on the stress-absorbing interlayer, reference should be made to the Standard Test Methods of Bitumen and Bituminous Mixtures for Highway Engineering (T0729-2000) and Superpave test methods.
(4) Thanks to its component materials and structural features, the stress-absorbing interlayer has good water damage resistance features.
