Fuel composition affects flame properties including heating value, and adiabatic flame temperature.
In turn, these properties changes gas turbine primary parameter such as compressor inlet mass flow, compressor pressure ratio, fuel mass flow, and cooling air mass flow.
Therefore, if the condition is changes (e.g., a decrease in heating value), the matching between the turbine and the compressor causes a change in the working pressure ratio of compressor thereby affecting the surge margin [3].

The surface quality is a critical factor affecting the performance and reliability of advanced ceramics.
Introduction A critical factor affecting the performance and reliability of advanced ceramics is the quality of the resulting surface by lapping and polishing.
Regarding 4 factors - 3 levels situations, there are 3 4 possible combinations and would require 81 trial runs for a factorial experiment.
In this study, standard 4 factors, 3 levels L9 (3 4) OA is used in this study.

Factors that can lead to instability of desulfurizer includes: (1) internal texture changes and irreversible changes of desulfurizer caused by sintering in the process of desulfurization/ regeneration recycle; (2) loss of active components; (3) stable sulfates produced during regeneration; (4) pulverizing problem of desulfurizer in desulfurization process.
However, the sorbent texture is one of the main factors that affect diffusion.
For desulfurization reaction, pore volume size of desulfurizer is an important factor that affects the desulfurization performance.
He also pointed that pore size, pore structure and crystal lattice defects caused by impurities or additives are the main factors that affect the sulfurization capability of sorbent.
Relationship between fractal dimension and porosity and average pore size Conclusion Besides the active component, the texture property of desulfurization sorbent is also a dominant factor that determines the desulfurization performance of sorbent.

The results show that the friction dynamics research on the involute helical gear meshing can be resolved by Virtual Prototyping Technology, which can provide a new method to study the tribological properties of the gear meshing.
The mechanical properties and performance of the helical gear transmission directly affect the whole mechanical system [1].
Studying the dynamics and tribological properties of the helical gear pairs during the gear meshing process is positive to improve the performance of the whole mechanical system.
After that, the physical properties are defined, the contact, rotation, rotation driving and torque load are added.
In this paper, the contact ratio of the virtual prototyping model is greater than 3, there are always three pairs or four pairs of teeth in the meshing process, and the meshing position is changing over time, these factors lead to some fluctuations of the friction force on the tooth surface, as shown in Fig.8.

Research Approach There are many factors to affect the strength of cement soil.
The mainly factors are as follows: (1) Cement: the type, mix proportion and mixing content of cement; (2) Soil property: the property of soil in different area is difference, and even for the soil of different type in the same area, there is also relatively large difference; (3) Degree of mixing uniformity: It is the degree of mixing uniformity of cement.
These factors will affect the strength of cement soil.
Therefore, the tests were done regarding several main influential factors.
Table 1 is the main physical mechanical properties of the soil samples.

Research for Specimen Preparation Technology of Basalt Fiber Reinforced Concrete As described above, BFRC specimen’s preparation technology may have effect on its mechanical properties.
Construction process has great influence on the mechanical properties of concrete and is based on specimen’s preparation technology.

Enhancement Mechanism Analysis of Basalt Fiber Reinforced Concrete Compared with the continuous fiber composite, short-cut fiber composite’s special nature brings more complex stress distribution when it meets external force, so fiber’s volume fraction, varieties, mixing technology and distribution’s directivity affect mechanical properties of composite materials.
The former is based on material properties’ superposition in composite; the latter is based on the perfect bond between fiber and matrix material.

Nanoindentation test is adapted to investigate the heat affected zone mechanical behaviour.
This material imperfection is characterized by a heat affected zone (HAZ) singular by its geometry and properties.
Welded zone Fig. 2: Tube ductile rupture from experiment The ultrasonic technique is very useful for non-destructive measurement of the mechanical properties of materials.
In this study, the nanoindentation with a pyramidal BERKOVICH indenter has been used as an effective tool to characterize the mechanical properties of welded joint and HAZ.
It allows admit that mechanical properties of the HAZ are homogeneous on few microns depths.

Lateral and edge wear of electrodes in micro-EDM affects workpiece shape accuracy.
There are many factors that influence EDM precision, the most influential property is electrode wear.
End wear causes errors in the electrode length estimation, side wear affects the shape of the hole created.
And, debris removal act as suspended powder will induce powder mixed EDM in the side gap, these factors destine that electrode wear is inevitable in µEDM.
ZrB2 is known to have many superior properties such as high melting temperature, high hardness, corrosion-and oxidation-resistivity and high electrical conductivity, being used for aircraft or rocket components working at an especially high temperature.

The structural physical properties are often uncertain due to manufacture errors, measurement errors and other factors.
However, due to the manufacturing errors, measurement errors and other factors, structural geometric properties and mechanical properties are usually uncertain.
However, due to the presence of uncertain factors, classical optimization method cannot solve structural design problems effectively.
Rao [5] discussed probabilistic optimization of design parameters for a mechanical system under random vibration circumstances.
The result means the fundamental frequency of non-probabilistic method is the least affected by uncertain parameters.

Significant deterioration in the mechanical properties of polyolefin is observed after two weeks of accelerated ageing at increased temperature, and for engineering polymers after a month [3].
Accelerated ageing method does not give the real picture of change (unknown factor of shorten the experiment time), such as ageing by weathering properties, therefore, must assume a large margin of error, but it is well suited for comparative studies of different types of materials [4].
Influence to changing climatic conditions on the chemical properties of the composites was investigated.
