As this review shows, irradiation can also be very useful for intentionally optimizing material properties and, when performed under very well controlled conditions, for understanding defects properties and their impact on large-scale material properties.
How might these irradiation conditions alter key properties such as mechanical behavior and hydrogen retention, the latter being a major safety concern for tritium?

Tagantsev et al. [36] reviewed the effect of strain gradient on polarization properties of ferroelectric thin films.
The occurrence of dead layer has been attributed to several factors such as a secondary low permittivity phase at the surface of the films, misfit dislocations and electric field penetration into the metal electrodes [58, 59].

Previous studies indicated that [3-4] both the primary α-Al and eutectic silicon were significantly refined by the preparation process of semisolid technique, and the mechanical properties were also improved.
Tp is thought to affect the microstructure of semisolid alloy by cooling rate, undercooling and superheat and so on [4].
With the increase of Tp, the cooling rate and nucleation rate of melt are decreased but the crystalline size is increased, resulting in the morphology of microstructure and properties of the alloy are worse.

Pores can be classified into three types, according to their size and their influence on the moisture transport properties of materials: · Micropores: are the smallest pores.
It is generally accepted that the drying rate at this stage depends only on external factors such as the RH of the air, the temperature and the air velocity.
Degradation processes by the action of salts are conditioned by very complex and varied factors.
However, the three main factors can be highlighted, together with environmental factors (temperature, air RH, radiation, and wind speed and direction): · Physical environment where processes take place (construction material); · Hygric characteristics (permeability to water vapor and absorption capillary), which influence the migration of solutions; · Mechanical resistance, which affects the way the material resists the internal stresses that are created in the pores.
The role of saline solution properties on porous limestone salt weathering by magnesium and sodium sulfates.

Fuel economy is a result of many factors, some of which are directly related to design while others are dependent on the vehicle service condition, road and weather conditions, weight, loading and operator behaviour.
Given their improved mechanical and thermal properties compared to pure aluminium or aluminium alloys, AlMMCs are a suitable replacement for, not only steel, but also aluminium alloys in various automotive components.
For the chassis, strength and toughness affect vehicle performance and survivability of occupants in severe crashes.
It was noted that there was need for systematic database that relates properties to processing parameters or between laboratory test data and actual performance.

The results demonstrate that the material properties of TRIP600 and DP600 are noticeably influenced by the pre-strain when the strain rate was over 1/s.
And this pre-strain will affect the dynamic tensile properties of sheet metals when car crash occurs at high strain rates.
In this study, the dimension of specimen was selected from the finite element analysis result considering the shape factors to induce the uniform deformation[12].
The material properties of TRIP-type and DP-type sheets were obtained from the static test as shown in Table 1.
This result informs that the material properties of TRIP600 and DP600 are noticeably influenced by the pre-strain at the intermediate strain rate.

Robot interaction includes the interaction between robots and that between robot and people, it is related to the factor of robot sociality, and affects the degree of robot integration into human society.
Inheritance technology can extend and modify the behavior of the original base class, by means of inheritance to achieve the public and unique properties of different robot models.

Though the melt routes is capable to produce a large metal foam ingot at relatively low cost, there is little room for improving mechanical properties by adding alloying elements or dispersing strengthening particles because of their narrow foaming and solidification conditions.
These results indicate that the dispersion of the TiH2 particles which affects final cell Fig. 3 Porosities of 4 kinds of specimens foamed under various foaming temperatures. morphology is nearly saturated over three ARB cycles.
These results indicate that ARB processing condition is quite important factor for the present bulk foaming process.

Applicable to a wider range of fields, because it is compared with the traditional neural network control technology, there is a new technology to its unique properties of neural networks can theoretically be any linear mapping can be an effective way to solve the non-linear complex system modeling, forecasting and other issues.
And fault-tolerant neural network is relatively strong, even if part of the neural network does not work, it will not affect the final calculation of the situation.
Learning BP neural network is composed of two back-propagation process forward propagation and error signal composed in the forward propagation, input samples from the input signal into the network layer, and finally sent to the output layer through the hidden layer processing, if the output does not match the expectations, put the back-propagation errors, according to changes in the above weight adjustment factor to adjust the weights until the output of the output layer of the network to meet the requirement.
