It indicates that the anisotropy of thermo-hydro-mechanical behavior of the argillite rock is the main factor affecting temperature distribution，pore pressure and stress fields.
Nuclear waste repositories of surrounding rock temperature, not only affect the physical properties of rock mass, water, but also for the rock mass seepage field and water should also have an important role in the field of groundwater; at the same time, as a kind of environmental factors, physical and mechanical properties of rock mass and heat has the important influence on the transmission; on the other hand, the thermal physical properties of rock mass discontinuity and the (joints, faults, fractures) respectively on the heat transfer and seepage of groundwater plays an important controlling role.
There are mineral deposition rock joint surface on the hydraulic properties and Mineral chemical reaction on the rock mechanics properties also have a great impact on [6].
Effects of kinetic factors and mechanism of nuclear waste Considering the diffusion of water, due to the thermal gradient and thermal stress field, seepage field and three field interaction mechanism follows a field, temperature stress caused by water flow

Welding thermal cycle of SMA490BW corrosion resistance steel with different heat inputs were simulated by using Gleeble-3500 thermo-mechanical simulator to investigate the grain size of the heat affected zone (HAZ).
Under the thermal effect of welding, evident change of microstructure and property in the base metal adjacent to the weld metal [2].Grain size is an important performance index, Grain growth is an important factor to welding metallurgy process and it shouldn’t be neglected, at the same time it often leads to welding heat affected zone becoming performance weak link, so grain growth in the welding heat affected zone directly affects the welding joint performance.
Influence factors of grain growth are the heating temperature and heat preservation time, heating speed, the chemical compositions of materials, the original organizations of materials and treatment conditions.
The chemical composition of the steel was listed in Table 1,and mechanical properties are in Table 2.
In general, the more tiny grain size is, the better mechanical propertiy is, therefore, SMA490BW corrosion resistance steel has good mechanical propertiy.

The environmental factors cause changes in the structural-mechanical properties of the concrete structure which can be divided into “internal” and “external” ones.
The external factors include those that act directly on the already formed structure of concrete in operating conditions.
These include mechanical, physical, chemical and other factors that affect the properties of the structure over time.
Introduction In the process of cement stone structure formation its strength increases, but as the structure forms and hardens, internal stresses arise that affect its properties.
The latter affect the concrete properties such as water permeability, corrosion resistance, etc.

The two main factors affecting the values here: the first factor is the physical structure characteristics of human waist and hips.
The factor of fabric Clothing material has a direct or indirect contact with the human body, it plays a decisive role on influencing the comfort of clothing .The material of the clothing affects the comfort mainly on fiber structure of fabric and its properties, fabric structure, mechanical properties, surface properties, and the heat transfer performance.
While the factors of influencing comfort of trousers are not isolated, they are in an interrelated organic whole and they are interacted by each other.
We should improve comfort of the trousers considering various factors on the basis of knowing the factors of influencing the comfort well and make the trousers fit the human body better.

As the material properties of an anode-supported PEN are dominated by the anode, the PEN is treated as a single material, i.e.
The elastic properties of Ni/YSZ given in Ref. [3] are used for PEN assembly.
The elastic properties of the mica sealant are orthotropic and assumed to be equal to those of single-crystal phlogopite mica.
From these results, it could be concluded that defect/crack type would affect the thermal stress intensity factor.
