Most of the materials are still needed by the experimental method, the test data is analyzed to obtain the thermal conductivity of the materials.
The test time is short, can cover a variety of materials, but the experimental formula is complex.
With the development of science and technology, more and more successive test method will appear.

Introduction Rammed earth material is a kind of building materials commonly used in traditional dwellings in china, it does not require a large number of energy consumption in the production process, it can be recycled to the natural environment, its negative influence on the environment is very small[1].
Thermal conductivity is an important thermal properties index that is a measure of thermal insulation performance of building envelope materials, which is influenced by the material type, dry density and moisture content of material.
Therefore, in order to improve the shear strength of rammed earth material, blindly increasing hydrated lime content is not absolutely science, but the hydrated lime optimum content shall be determined through test.

Microencapsulated phase changed materials (MicroPCMs) have been widely investigated since 1970s in light of the requirements of the renewable and clean energy storage materials [2].
To the best of our knowledge, however, little information is available on preparation of MicroPCMs containing thermochromatic materials.
In addition, the incorporation of thermochromatic powders does not play the role of heterogeneous nucleating agents to C18 crystallization Acknowledgements The authors appreciated the financial support from the National Natural Science Foundation of China (No. 20904040), the Opening Project of State Key Laboratory of Hollow Fiber Membrane Materials and Processes (Tianjin Polytechnic University) and the Science and Technology Development Plan of Tianjin (09ZCKFGX02200).

Introduction Functionally graded materials are inhomogeneous composites within which materials properties vary continuously.
This is achieved by gradually changing the composition of the constituent materials, usually in one direction, to obtain smooth variation in material properties [1].
Materials properties are graded in the thickness direction according to a power-law distribution.
The zirconia and titanium alloy are selected for the two constituent materials of the plate in the present examples, referred to as ZrO2/Ti-6Al-4V.

The three test methods were: a) ISO 4049 for dental composites, 3-point bend test b) EN 843-1 for ceramic materials, 3-point bend test and c) ASTM F-394, biaxial ball-on-disc for ceramic materials.
Several standard methods exist to measure the flexural strength of materials [2].
When studying dental materials the test method should resemble the filling of a tooth cavity.
When testing ceramic materials it is important to relate the results to the fracture toughness and microstructure of the material.
