Determining these values by torsional vibrations is based on measuring the vibration factor δ.
The relaxation time of the structure and stabilization of the properties can be recommended as the value of τtreat.
The best service properties of ribbons were obtained in the third regime.
The physical properties versus the annealing temperature are shown in Table 1.
The model being beneficial is attributed to its retaining information on the actual connection between the liquid and solid states, and implies the possibility to forecast the results of physical-mechanical impacts on the melt, affecting the final product properties.

In addition, the high requirement on mechanical property of oscillatory key parts are demanded [10-12].
The factors which can affect the tillage resistance of subsoiler include tillage depth, (whereis maximum longitudinal length of the soil-engaging part of subsoiler, is tillage depth, is named longitudinal/depth ratio), structural shape and dimensions of subsoiler, penetration angle and soil physical properties.
The penetration angle is another important factor which can affect the tillage resistance and mechanical property of subsoiler.
The penetration angle which is either too large or too small can directly affect penetrability of subsoiler and increase the tillage resistance.

It has been developed rapidly because of its good comprehensive properties].
Ceramic particle reinforced Cu-base composite materials have greater electrical and thermal conductivity, higher wear-resistance and better high temperature properties.
The cutting factors is selected to be ap=0.1~0.5mm, f=0.1~0.2mm/r, n=1400r/min (v=0.88m/s) and 320r/min(0.22m/s).
When the cutting factors are bigger, the F values are closer.
There is a great difference of the physical and mechanical properties between its reinforced body and substrate Cu.

This paper makes an evidential analysis of Balidian catering buildings in Mount Shaohua scenic area by the typical demonstration; This paper analyzes the factors which influence the landscape architecture design and develop a method of the appropriate technical support for the landscape architecture design in mountainous scenic areas.
The landscape architecture design in mountainous scenic area is affected by many factors, which is a comprehensive space coordination issue.
The relationship between conditions of the natural resources and the designing of the landscape architecture In the natural environment, those natural elements that are related to the development of human society and can be used for producing useful value and affecting the labor productivity are usually called natural resources.
Machines, tools, skills and abilities are only one factor of the technology.
The type of connection is up to the difference between mechanical properties of different materials.

Silk hydrogels have mechanical properties and structural features that are similar to load-bearing soft tissues, and can be implanted for tissue restoration.
Introduction Silk fibroin (SF) protein, as a nature polymer, exhibits impressive mechanical properties as well as biocompatibility.
Especially injectable SF hydrogels, which have mechanical and structural properties similar to some tissues and extracellular matrices(ECM), have good effect in bone defect repair[2-3].
Understanding the inherent mechanism and the related factors is important for improved handling of this unique protein.
The particle size of initial solution may affect the silk fibroin gelation.

Introduction Landslides are caused by natural factors, such as river erosion, by human activities, torrential rains, earthquakes, and flows of underground water.
Because of the severity of the damage, it is necessary to understand the factors that contribute to the development of landslides, their distribution, and how they evolve once movement of the materials begins.
This difference can be explained by differences in the physical properties, such as the landslide’s internal structure and composition.
Landslides of materials with different physical properties will have different internal friction, which will affect the relationship between movement distance and the angle of internal friction.
This can also explain how the lithological properties of the sliding surface base of the landslide influence the movement distance.

Testing under different temperatures is important because the temperature significantly affects the material properties.
The surface of polymers is smooth, which leads to low friction factors and also has good fouling characteristics.
The important factor is the stress inside the wall of the fibres.
The properties of bundles and conditions of these tests are described in Table 1.
A pressure limit of 7.5 MPa was calculated based on the mechanical properties of polypropylene.

It is, in particular, the stiffness, the number and the arrangement of rubber bearings that is the essential factor affecting the dynamic characteristics of the articulated column system.
The designed solution allowing controlling the dynamic properties of the column system with articulated joints and elastically embedded diaphragms creates preconditions for controlled dynamic properties of the system offering the possibility of the system’s use under extreme conditions and situations (e.g. technical and induced seismicity, natural seismicity, etc.).
The stiffness or dynamic properties may be modified by modifying the stiffness of the connecting bearings of the diaphragm and cross bars.
Mechanical properties of rubber.
