Composite materials.

Only the numerical method can be applied to calculate the sound transmission loss (STL), however, in the cavity of the air cleaner there are some filter materials whose acoustic property is hard to describe precisely even if using the numerical method.
In the experimental duct system，a filter material was mounted between two testing pipes.

On the other hand there are several properties which are not easily reproducible in the most of the materials characterization, and particularly in the quantification of the material.
In this paper a concept of traceability is introduced for the measurements of materials properties.
Particularly important is the development of reference materials, which are described below.
By the agreement of ISO/REMCO, they are stated as folloows: • Reference Materials(RMs): A material or susbstance, one or more properties of which are sufficiently well established to be used for calibration of an apparatus, the assessment of a measurement method, or for assigning values to materials.

Figure 1 shows the properties comparison among the homogeneous metallic materials, composite and functionally graded materials, the performance of functionally graded materials have obvious advantages.

Besides stone, building materials of Mount Lu villas also include metal tile, flashing, brick
(1) Stone In the selection of building materials in the west and China, in addition to natural factors, more importantly, different culture and ideas matter.
It is worth mentioning that roof materials of the church are different from other villas, for most villas in Mount Lu, their roofs are made of metal materials, while 2 roof slopes of the No. 283 church are made of small bluestones which are from the south of Mount Lu.
Analysis of building materials used in key parts of villas in the Mount Lu (1) Base It is also called foundation.
Cross hollow masonry structure of these materials cover the above space, enclose the walls and support the roof.

The phenomenon that the impact toughness of materials will decrease when the environment temperature is below the critical brittle temperature of materials is called low temperature brittlement of materials.
But the cutting force is differ from different materials

A Material Removal Modeling of Chemical Mechanical Polishing Based on Micro-contact Mechanism Shiwen Dua , Yongtang Lib，Jianjun Song, Huiping Qi School of Material Science & Engineering, Taiyuan University of Science and Technology Taiyuan,030024,China atykddsw@126.com, bliyongtang@tyust.edu.cn Keywords: chemical mechanical polishing; material removal rate; planarization; hyper-elastic Abstract.The model proposed integrates process parameters including pressure and velocity and other important input parameters including the wafer hardness, pad roughness, abrasive size, and abrasive geometry into the formulation to predict the material removal rate.
Material removal rate of single abrasive particle is calculated by the abrasive wear theory.
The schematic of a particle removal material model is shown in Fig.3.
