The most important factors affecting the strengthening of the ceramic pellets were evaluated.
In all cases, both the structure and the mechanical properties of the polymer coated ceramic samples are affected by various factors of the coating process, namely: a removal technique of an excess polymer, concentration of the polymer in a solution, a heat treatment stage, a number of dipping (Table 1) and so on.
The statistical experimental design can determine the factor effects on characteristic properties and select the optimum conditions for these factors.
By the raw data analysis, the effects of several factors on the mechanical strength have been analyzed.
For ceramics, its density and pore size seriously influence the mechanical properties.

The results show the results calculated by software have good agreements with the tested ones; slender ratio, eccentricity and the thickness are the most effective factors on the mechanical properties of slender STSRHC.
This paper is mainly to study on the factors influencing on the mechanical properties of slender STSRHC, based on the finite element software.
HH is used for studying on the influence of moment of inertia of inserted steel on the mechanical properties of SHSRHC.
Parameter Analysis In order to get the results about different factors that influence the mechanical properties of STSRHC, the parameters of specimen HL are changed for analysis, and the results are shown in Fig. 4-Fig.9.

It should increase the harden ability of the alloy elements to improve mechanical properties of the steel HG785D.
Table 3 Mechanical properties of the tested steels NO.
In the actual production, there are many inevitable defects in raw ingots and the microstructure is the key factor which affects the high ductility of heavy ingot.
The optimum process of controlled rolling and accelerated cooling for obtaining better mechanical properties is given.
Rolling passes, reduction and TMCP are the decisive factor of the properties.

Particular attention is paid to factors influencing mechanical properties and castability.
The nature and level of alloy addition is in all cases an important determinant of castability (cracking and fluidity) and mechanical properties (strength, ductility and creep resistance).
The interplay of these factors shows considerable variation between different alloy systems.
Improved understanding has been achieved as to the key factors that affect castability including hot tearing [1, 2], room temperature mechanical properties [3], creep resistance [4, 5] and corrosion behaviour [6], of high performance alloys in particular.
Carlos Cáceres is thanked for his many discussions on the relationship between microstructure and mechanical properties in magnesium alloys.

Local mechanical properties were determined by the microhardness and nanohardness measurements.
Ring compression testing (RCT) was employed with the aim to obtain the macroscopic mechanical properties.
The experimental results confirmed that hydrogen as well as the cooling rate substantially influenced the microstructure and affected both local and macroscopic mechanical properties.
Hence, the fraction of the β-phase and oxygen content in the phase are the most decisive factors causing the fuel cladding embrittlement.
The loss of mechanical properties should be then caused mainly by the precipitated hydrides.

The changes in properties depend on several factors, such as the welding process, welding parameters, and composition of the steel.
The use of alloying elements, such as niobium and molybdenum, can have a significant effect on HAZ properties.
This could suggest that even with higher t8/5 time, it can be possible for HAZ area to achieve similar mechanical properties equivalent to the base metal.

Based on definition of porosity, permeability model of gas-bearing coal was build which took porosity gas pressure, gas adsorption expansion, temperature and crustal stress into account, and the factors affecting the permeability of gas-bearing coal has been analyzed theoretically.
There are a lot of factors influencing coal permeability.
All kinds of influencing factors should be considered if we want to obtain the expected extraction results.
Analysis of Factors Affecting the Permeability on Coal Containing Gas The permeability model of gas-bearing coal was analyzed using coal sample from the coal seam JI-15 of 1st Coal Mine of Pingdingshan Coal Industrial (Group) Company, and the mechanical parameters were shown in Table 1.

The mainly influencing factors were analyzed including vibration acceleration, frequency, exposure time and other factors.
Influencing Factors In a certain vibration environment of the human body, the blood capillary tension and smooth muscle contractile properties change.
