Introduction The strain control rotational rheometer, quipped with different methods of steady, transient and dynamic tests, has been maturely applied to study rheological properties of polymers.
During the process, melt spinning is a key step impacted by rheological properties of PCS melt.
Temperature control was an important factor on PCS melt rheological test.

Generally, W/B is a significant influencing factor on properties of concretes or mortars.
Its physical properties are given in Table 2.
Specimens in the forms of 100 mm ×100 mm ×100 mm cubes and 100 mm ×100 mm ×300 mm cylinders were cast for measuring the mechanical properties of UHSC.
(1) Ultra-low W/B between 0.14 and 0.22 at a constant increment of 0.02 affected the mechanical properties of UHSC remarkably, while RPC or UHSC with coarse aggregate
Explosive Spalling and Residual Mechanical Properties of Fiber-Toughened High-Performance Concrete Subjected to High Temperatures.

By adjusting the technical parameters, we can obtain different coatings with the desired properties, such as corrosion resistance, wear resistance and mechanical properties[1].
The organic fibres not only can affect adhesion strength with the nickel coating but also has great influences on the technical conditions of sintering procedures as well as the properties of the hollow nickel fibres.
In this experiment three key factors were considered.
Cheap fibres were considered with the precondition of the above two factors well satisfied.
By comparison the properties of different fibres, we choosed the polyacrylonitrile fibres as the templates of electroless plating.

In recent years, some scholars begin to combine digital image processing (DIP) technology and geomaterials, with different image information corresponding to different geotechnical materials, to analyze the mechanical properties and monitor deformation of materials[1,2].
Pixel unit is the basic processing objects of the image, with two properties: coordinates and intensity.
Figure 5 shows the total pixel number is 441×599, actual size is 221m×300m, proportional conversion factor R is 0.61475m/pixel, actual area of each pixel is 0.25083 m2.
Compared with conventional modeling, still the following deficiencies exist: (1) Compared with the literature[2-6], although the total number of pixels greatly improved, the establishment of a greater number of pixels or further reduce the size conversion scale factor will greatly affect the Flac3D calculation speed, time-consuming; (2) Although achieving unified operation to the pixels of the same region with the same gray degree to control element size in the horizontal, further exploration of independent subdivision of the grid in the longitudinal direction is expected.

The concrete composite material with basalt fiber as enhancing system in it has a lot of advantages ,including excellent mechanical properties , high temperature resistant, resistant to acid and alkali, low cost, environmental protection materials and resistance production process.
Damage of northern environment of freezing and thawing on the properties of the composite material has become a new hot issue.
We can use CBF as reinforcement to make all kinds of excellent properties.
But current research on the properties of basalt fiber concrete frost resistance is relatively limited.
Thus, concrete reinforced by basalt fiber can effectively improve the frost resistance itself, and it has the best antifreeze performance with 0.3% basalt fiber. 4.2 Experiment Result Analysis The main factors influencing the concrete freeze-thaw performance has two aspects.

Compressive residual stress induced by water peening was measured to investigate the surface strengthening effect as a quantitative factor.
The main parameters and mechanical performance of the helical gear part are given in Table 1. ⑤ ⑥⑦ ⑤ ⑥⑦ Fig.1 Schematic of water peening equipment Fig.2 Photo of the specimen and nozzle Table 1 Main parameter of the gear shaft and mechanical properties of SCr420H steel No. of teeth 17 Young's modulus 219.4 GPa Module 2.22 Poisson's ratio 0.26 Pressure angle 18° Yield stress 400 MPa Helix angle 25.7° Hardness (Hv) 180 Out circle diameter 48.37 mm Machine method Shaving Pitch circle diameter 43.89 mm Heat treatment Carburized quenching B A C Water peening conditions.
The stress factor of the X-ray diffraction method was -318.71 MPa/deg.
In order to examine the water peening affecting area for the gear shaft with complex shape, the specimen was pre-coated blue painting on the whole surface of the gear.
For the industrial heat treatment process, there are many influences factors which lead to uneven heat transfer and in turn result in heterogonous microstructure and mechanical properties of quenching steel.

Part of polymer phase fills capillary pores and has a major influence for final properties of the matrix.
The properties of hardened cement paste are well-known.
Improved properties in adhesion to the substrate.
Consequently, the properties of latex-modified mortar are markedly improved over conventional mortar.
The properties of fresh and hardened mortar are affected by multiplicity of factors such as polymer type, polymer-cement ratio, water-cement ratio, air content, and curing conditions [1].

Deposition temperature is a key factor influencing the growth morphology of thin-films, aiming at this phenomenon, a precise control system of deposition temperature in ultra-high vacuum is developed in the paper.
And the substrate deposition temperature is a key factor to affect the morphology of thin-films in the process of growth because it is not only related to the molecular diffusion style and diffusion coefficient of single molecules and molecular clusters on the surface, but also associated with the film growth morphology, crystalline state and optical properties [6-8].
The ultra-high vacuum conditions should not be affected by used components in a wide range of temperature variation; (2).
Therefore, the mechanical connection relationship between the substrate carrier and the sample retainer can cause a certain temperature gradient between theirselves.
It is worth mentioning that the mechanical installation of such a system still needs to be optimized, it is undoubtedly that further controllable temperature range of the system can be expanded if the more close mechanical connection between the substrate carrier and the sample retainer is established.

The nano-structured TiO2 is of prime interest owing to its high catalytic activity, enhanced mechanical properties as well as distinctive optical properties when compared to the bulk material.
One of the key factors that affect the performance of thin film prepared via sol-gel dip-coating method is the thickness of the film, which on the other hand is influenced by many other factors such as the viscosity of the sol, the number of coating layers, and the dipping rate [8-10].
In addition, the crystal structure and morphology will also be affected by the increment in coating cycle [11].
It can also be seen that the surface morphology of the coating is greatly affected by the number of layers.
