It has been found that the Nano-pore-throat takes more than 60 percent of the total pore-throat of the low permeability reservoir and it is the key factor affecting the flow capacity when the permeability is less than 0.5×10-3μm2.
And Micron-pore-throat is the key factor affecting the flow capacity of low permeability reservoir.
The nanoscale pore-throat takes more than 60 percent of the total pore-throat and microscale pore-throat takes less than 5 percent when the permeability is less than 0.5×10-3μm2, while the key factor affecting the flow capacity is sub-microscale pore-throat.
The key factor affecting the flow capacity is the sub-microscale pore-throat when the permeability is smaller than 0.5×10-3μm2, and that would be microscale pore-throat when the permeability is larger than 5×10-3μm2.

Because ink permeates the interior of material, therefore small scratch can not affect its appearance. [1] Problems The application of WPC in furniture market, environmental art and sanitary location are restricted by various factors, such as production mode and surface quality.
On the other hand, aesthetic and diversified forms, clean and comfortable requirement are all equally important; all of these factors shall be considered in the furniture market.
Rockwell hardness of WPC less than 58 HRC is too insufficiency according to the material properties.
The mechanical properties of WPC satisfy the application of art furniture and classical painting style, and it has a certain market advantages for its low cost.
Besides, it can not affect the whole appearance （Fig. 4）.

The aim of this study was to compare the properties of PKRC with and without SV after 200 days of natural weathering exposure.
These factors may affect the environmental durability and the long term performance of natural fiber reinforced composites.
In facts, the degradation of mechanical properties was improved with the help of surfacing veils.

The mechanical property is a determining factor facilitating the use of HFs.
In this study, the effects of CCTO addition on the morphological and mechanical properties of the CCTO HFs are evaluated.
The possible explanation for this enhancement in mechanical properties is that the increasing the CCTO content lower the specific surface area and reduce the porosity in the structure which leads to the enhancement of mechanical properties.
Table 1: Morphological and mechanical properties of CCTO HFs.
Finally, the addition of CCTO considerably improved the mechanical properties of HFs.

Degradation of the Building Structures Due to Carbonation of Concrete Jan Pasek1,a*, Ludek Vejvara1,b 1 University of West Bohemia, Faculty of Applied Sciences, Department of Mechanics, Univerzitni 8, 306 14 Pilsen, Czech Republic apasek@kme.zcu.cz, bvejvara@kme.zcu.cz Keywords: Concrete structures, carbonation of concrete, corrosion of reinforcement, influence of concrete properties, influence of environment properties, influence of age of structure, durability and reliability of reinforced concrete structures.
The paper refers about seriousness of the current technical state of reinforced concrete structures and influence of the most important factors on the course of their degradation caused by carbonation and specifies principles for designing new reinforced concrete constructions.
Analyses of the factors influencing process of carbonation of concrete Carbonation of concrete affects all monolithic and prefabricated concrete and reinforced concrete elements exposed to influence of carbon dioxide and humidity.
An analyses made on circa 50 buildings in the CR was focused on evaluation of the influence of above mentioned factors on the process of carbonation.
The most significant inhibitor of carbonation seems to be the quality of the concrete described by two factors – the class of the concrete and its structure.

The mixing speed is the most considered parameter which affects the homogeneity and properties of the PM product.
The sintered specimens were then analyzed based on their microstructure, physical properties, and mechanical properties.
Hardness testing was carried out on the sintered specimen using Rockwell scale F to determine the effect of variations in the mixing speed on the mechanical properties.
To find out the relationship between the effect of homogeneity on the physical and mechanical properties of Cu-Sn, the density, porosity, and hardness analysis was carried out.

Introduction Titanium matrix composites (TMC) have higher specific stiffness/strength, higher wear/corrosion resistance, higher anti-fatigue performance and better high-temperature properties, which are recognized as one of the new materials to replace titanium alloys.
Most of the research mainly focused on the tool life, cutting temperature and cutting forces investigation based on the single factor method in which the significance of the affected factors and the interaction between the factors were not studied.
Thus, it can be concluded that radial depth of cut and cutting speed are the two significant influences factors based on the Taguchi prediction that the larger different between value of S/N ratio will have a more significant effect on cutting force (F).

The stability of the properties of the T8 as welded condition was investigated after a 1000 hours at 85°C exposure.
The second one tested by DLR aimed at investigating the local properties of the microstructure.
Fatigue tests were performed on two types of specimens representing two stress concentration factors (un-notched Kt 1,036 and Kt 2,3 with a 6,35 mm hole diameter) and according to ASTM E466-82.
The good ductility of the weld nugget and the surrounding zones might also explained the promising behaviour in fatigue crack growth and in fracture toughness but other factors such as residual stress field [3] may also contribute.
Even if the post welding aging provides a hardening in the surrounding zones of the weld nugget, the global static and fatigue properties of the T8 post welding aged weld are similar to the T8 as welded condition.

The simulation result shows this can significantly improve driving comfort, shift transient property and extend service life of clutch.
Introduction Traditional vehicles must separate clutch during the process of start-up and shifting, which affected by many factors such as environmental factors, vehicle operating status, the driver's willingness, etc.
Firstly, they analyze the impact of a motor on traditional powertrain system and how the motor affect the way of driving, braking and shifting.
This will can significantly improve driving comfort, reduce shift transient property and extend service life of clutch.
Moreover, it can significantly improve driving comfort, shifting transient property and extend service life of clutch.

Generally, cracks are initiated in cementitious materials at the nanoscale [3], then grow into micro and macro cracks that negatively affect the mechanical and durability properties.
Besides the CNTs' physical properties' effect on the mechanical properties, some other essential factors and interactions must be studied.
Flow properties Flow properties like flow diameter, yield stress, and plastic viscosity indicate the cementitious composite's stability, constructability, and early-age characteristics, which affect the mechanical properties.
CNTs have mechanical, electrical, and thermal properties.
These cracks affect the durability and mechanical properties.
