However, the frequency of the plants watering normally is affected by several factors such as weather conditions, maturity of the plant, species and soil types.
When the root density is high, roots and soil create a complex system that can be considered as a new matrix that works as a unique phase in which soil and roots properties cannot be well distinguished [6].

Introduction The friction stir process is major interest of welding of aluminum since it improves the joint properties.
In addition, extensive softening will occur in the HAZ, thus lowering the mechanical properties.
Defect free welds with good mechanical properties have been made in a variety of aluminium alloys, even those previously thought to be not weldable with conventional methods.
There have been a lot of efforts to understand the effect of process parameters on material flow behavior, microstructure formation and hence mechanical properties of friction stir welded joints.
In order to assess the influence of factors on the response, the means and Signal-to-Noise ratios (S/N) for each control factor were calculated.

The acceptability of polymer matrix composites for various industrial applications has been increased over the years due to their better mechanical properties.
It affects the drilling behavior of the composites by high tool wear and higher surface roughness of the drilled hole[3].

Introduction Viscoelastic properties include elastic and anelastic properties.
But many factors can affect the skin viscoelasticity, such as gender, specific location, hydration, PH value, relative humidity and different time periods.
He measured the mechanical properties of rabbit skin through two-dimensional stress device[3].
The method has been used to study effects of different factors on skin, such as aging, location, gender, etc.
Measurement of compressive or tensile in vitro as a classic, is an invasive measurement method, but it can accurately measure the various mechanical properties of skin, and provide a basis for skin closure, as well as a quantitative assessment of graft wound healing and scar formation factors; And comprehensive assessment on the skin can be carried out through inhalation method.

According to the two important factors of the melt temperature and mold temperature, the paper designs three plans, analyzed rubber melt flow front temperature, volume curing rate and volume curing rate at the end of filling in different melt temperature and mold temperature and found the best solution, so that curing time was shorten and production efficiency was improved under the precondition of filling smoothly mold and ensuring quality of products.
During vulcanization molding， rubber change from the linear structure of the macromolecules cross-linking to a three-dimensional network structure of macromolecules, so as to significantly improve the physical and mechanical properties of rubber[3].So the study problem to rubber products is much more than ever.
Lower flow front temperature will affect the melt material liquidity, make the filling difficult and affect the appearance of product.
(a) (b) (c) (a - plan 1; b - plan 2; c - plan 3) Fig.3 Flow front temperature We can see from the graph: the third plan in the three plans has the minimum flow front temperature, and the front melt with the mold filling process has little cross-linking reactions, therefore it is not easy to produce weld marks in meeting point of flow materials and affect the quality of products.
According to the above results, finally the third plan is selected considering the influence of all factors. 3.

Such processes typically introduce residual stresses into the coated surface, which in turn affect efficiency of coatings and play an important role in coating durability.
This quantity is related to different factors: the size of the grains, the residual micro-strain (II order) and the instrument used.
The second point that can be evidenced is that shot peening is able to work harden the coating: this is clear by observing the FWHM trend and confirm the ability of shot peening in modifying the material state and the material properties also for cold sprayed coatings.
On the basis of the experimental results it can be said that an improvement of mechanical properties of cold sprayed layers after shot peening is expected, even if a more marked effect can be reached only by changing the treatment parameters.
However, the results suggest that by using peening parameters able to increase the impact energy of the shot flow a more remarkable residual stress state could be reached and a more marked effect on the mechanical properties.

Mechanical properties, (macro/micro) structure were investigated for the process variables recorded in Table 2.
The heat affected zone (HAZ) lies closer to the base metal (BM) and it may encounter a thermal cycle that changes the microstructures and/or the mechanical properties due to over-aging without any plastic deformation.
This zone may encounter a thermal cycle due to welding without changing its microstructures or mechanical properties.
Also, the fully bonded length was confirmed to be the main factor affecting the mechanical properties.

Although the mechanical properties of expanded polymer materials have been studied [1-5], the quasi-static and impact properties and measurement methods have not been reported in foamed films.
In the present study, we evaluated the compressive properties of foamed PE film.
Thus, the strain rate sensitivity in the high strain region was caused by mechanical properties of the PE base material.
It is necessary investigate the mechanical properties of the dynamic strain rate in mobile electronic devices.
Additionally, the properties of the PE base material were unclear.
