Table 1 lists most of the current application phase change building materials [4].
In China , by adding phase change material to the matrix we got insulation materials that could be used for building envelope.
By the addition of phase change materials heat storage properties of materials are improved,and the thermal stability of the material is also improved, and does not affect the strength, durability and other properties of materials. [5] The advantages and disadvantages of phase change materials Composite technology of phase change materials mainly includes:(1)put thePCM package ( including container packaging, microcapsule encapsulation ) into building materials;(2) permeate PCM into porous matrix by immersion ( such as gypsum wallboard, concrete etc. ); (3)the PCM is directly mixed with building materials; (4) add the organic PCM to the building materials after emulsion.
Phase change materials as a new building insulation materials, has great advantages compared with sensible heat insulation materials, but it also has some problems, mainly includes[7]:(1) Type of phase change material is not available; (2)Preparation process of phase change building materials is not perfect, in order to prevent leakage.Considing with evaporation of phase change when used, they should be packaged, but package technology of phase change materials at present is still not perfect, this is also important problem of the phase change materials; (3)The high cost of the phase change materials when used.

Shear Mechanical Properties Characterization of Material via Ultrasound Vibrometry Ke Chen1,a, Jiangli Lin1,b, Guangfu Yin1,c and Yi Zheng2,d 1College of Materials Science and Engineering, Sichuan University, China 2Department of Electrical and Computer Engineering, St.
Measurement of mechanical properties is very important in material science research area.
Introduction How to measure mechanical properties of materials and biological tissue noninvasively is an important issue in material science, non-destructive test, and medical diagnosis.
A usual approach for noninvasive measurement is to quantify responses of materials stressed by external force.
