Figure 2 shows YBCO thin film of c- axis on LAO substrate，and its Temperature of growth is 800℃,The surface of the film is dense ,and it’s hard to find square hole and slot ,thus ,the passage of current is easier ,he superconducting thin film will be up to the critical current density requirements .It follows that the surface morphology of the films in the film growth is often our most basic information concerned ,Often affect the device fabrication process ,and even affect the physical properties of the material itself ,thus ,the research for the effect of surface morphology of thin films on their properties is significant.
In addition, according to the different crystal type, crystal film morphology is also differ in thousands of ways ,the influence factors is also perplexing and contacted.
Factors that affect the film morphology The optimality of crystal face :In the process of crystal growth ,the growth velocity of different crystal face is different, growth velocity can be divided into two :growth velocity of transverse direction and growth velocity of normal direction ,and they are mutually related to each other and mutually restrict each other，they both are decisive factors of the film morphology.
The different crystal face has crystal surface energy ,surface energy differences will lead to differences in the growth rate of each crystal face, thereby affecting the optimality of growth.

The purpose of the work was to assess the impact of construction factors on weldability of MSRB alloy.
Structural factors affecting weldability of magnesium casting alloys include: cast construction solution, cast complexity degree, differences in wall thicknesses, casting stiffness, and notch presence.
Literature does not describe the impact of these factors determining weldability of magnesium alloys.
Thus, there is the need for determination of construction factors affecting the weldability of the MSRB alloy being used for large-size casts for the aircraft industry.
Table 1 presents the chemical composition and mechanical properties of the delivered pig sows of the MSR–B alloy.

The practical application has lay more attention on the evolution law of macro-physics, mechanical property of damage process, the great change of mechanical property of concrete can show that negative temperature brings about degradation to concrete structure.
In the fractal dimension of crack expansion form, there are information of crack quantity, crack length and tortuous degree of crack expansion path in the observation area of sample surface, and many factors as microscopic structure, loading condition.
Modulus of elasticity of concrete has a lot of factors that contains some factors affecting strength, the strength of concert in the negative temperature is very low, its volume expands when the water become ice, and there are many tiny crack inner concrete, which causes the damage of concrete inner structure; and with the increase of temperature to be positive, anhydrated cement particles inner concrete continue to hydrate, new gels form, structure damage inner concrete heals further, and the damage degree decrease [11,12].
Conclusions Mechanical property variation of high-strength concert, which is under standard curing and negative temperature, has been studied and the evolution of damage process based on mesoscopic damage mechanics.

Introduction Aluminum profile extrusion with two-hole dies refers that the high temperature aluminum alloy, according to a certain speed, is extruded from the die cavity by extrusion machine, in this way, through an extrusion process can get two specific shape, size and good mechanical properties aluminum profile[2].
The mechanical properties parameters of materials after heat treatment is as follows: elastic modulus is E=210GPa, Poisson's ratio is µ =0.30, specific heat capacity is C=460J/ (kg· K), the coefficient of friction between the die surface and blank is f=0.3.Blank is aluminum alloy 6061, the forming process parameters are shown in table 1[5].
The influences of various factors effect on the size of the sort: blank temperature > extrusion speed > mold temperature > welding chamber height.
While pressing the average squeeze pressure P and welding chamber height correlation, correlation of other factors is almost equal.
The factors affecting the order as: welding chamber height >die temperature > extrusion speed> billet temperature.

In combination with temperature, strain rates directly affect the material microstructure and, hence, the mechanical properties of processed material [5].
Such condensed finding model can be readily used in control frameworks architectures to fabricate AZ31B sheets with predefined mechanical properties.
The two main factors that directly affect the simulation time and the result’s conversion for any FEM simulation are the mesh size and time step.

Vibration causes fruits mechanical and physical damage during transportation and affects the fruits storage characteristics and sales.
Therefore, study on the vibration load caused injury factors have very important value [1].
The initial mechanical properties and damage fruit and vegetable researches focus on agricultural products, for agricultural products post-harvest storage and sorting, grading etc..
The vibration acceleration is one of the important factors in injury, so layer numbers are an important factor.
These two layer numbers are the damage factors of Huangguan pear.

Through the analysis of performance of ordinary cotton and organic cotton knitted fabrics, it was found that the mechanical properties of the organic cotton knits are somewhat less than ordinary cotton knits and there is no difference in wear ability between the two.
Fabric thickness has a great influence on physical properties of the fabric, in the same conditions, fabric abrasion resistance and warmth retention will increase with the thickness increasing; the fabric thickness may affect wear ability, such as abrasion resistance, air permeability, wind resistance, rigidity and drapery.
