In this study, the thermal properties of a kind of new geotextile materials, so called controlled permeable formwork (CPF), were studied.
As a new geotextile material, the properties of CPF are seldom studied so far [2].
The performance of CPF will be changed during the transportation, storage and usage due to the affection of external factors such as the change of temperature.
The change was negligible and won’t affect the normal use of the sample.
The thermal stability of CPF is very good and the change of the mechanical properties of it is negligible for general use in construction.

The structure and properties of in situ Cu-Nb composites have been studied by the methods of TEM and SEM, X-ray analysis and mechanical testing.
However up to now not all the factors responsible for high mechanical characteristics have been revealed, and for further improvement of properties it is of importance to study the effect of doping and modification of processing schedules on the structure of these materials.
Their structure, texture and mechanical properties were studied by the methods of transmission (TEM) and scanning (SEM) electron microscopy, X-ray analysis, tensile testing and microhardness measurements.
That is why one of the goals of this paper was to study the effect of intermediate annealing on the structure and properties of Cu-Nb and Cu-Nb-Zr composites.

Environmental and climatic factors directly affect the temperature of asphalt pavement layers.
Air temperature is one of the most important environmental factors that significantly affect the temperature distribution profile of asphalt pavement layers.
Air temperature is one of the most important environmental factors for which influencing the mechanical properties of asphalt mixtures [3].
Climatic factors consisting air temperature and humidity are interrelated and opposite to each other.
Asphalt pavement temperature profile is significantly associated with climatic factors.

The residual stress manifested from higher to lower in the depth direction of the coatings Introduction WC-Co coatings are professional materials using for protecting in the wear circumstance for its excellent mechanical properties.
In recent years, the researches about the WC-Co coatings’ mechanical properties were highly concerned.
M.Watanabe discussed the influence of different WC-Co particle size on the HVOF sprayed interface fracture toughness, the consequence demonstrated that the microstructure, density, the WC particles embedded in the coatings and the volume in the binder metal are all the important factors which affect the coatings [4].
In this paper, nanostructured WC-17Co coatings, nanostructured WC-12Co coatings, conventional WC-17Co coatings were prepared by HVOF spraying technology to investigate the mechanical properties and the residual stress, which may provides an appropriate theoretical basis for the application of WC-Co coatings.
The micro-crack spreads along the phase interface where the brittle phase are more in the Co rich area , where there are more different properties in the Co rich area and W rich area, where there are more defects close to the intend end in the W rich area, even spread through the WC particles in microcosmic.

Thermal properties of Si mechanically alloyed with FeSi2 and CrSi2 were characterized for the samples with different volume fraction of the disilicides.
Such an unusual combination of properties may result in formation of very efficient thermoelectric materials.
Mechanical alloying followed by spark plasma sintering has been widely used for preparation of Si-Ge alloys [11].
Most likely there are several factors that affect thermal transport in these materials and which are at play at different sintering conditions.
Introducing FeSi2 and CrSi2 into silicon matrix may have different effect on thermal properties which is linked to different sintering condition.

Three factors may have contributed to this improvement.
The frost resistance of concrete is also affected by its porosity, aggregate properties, and climatic conditions [72-75].
