Among others, one of the most remarkable properties of this sensing principle is the capability of being used through a wide viscosity range.
This is the reason why oil must be replaced before it loses its lubricant properties.
But the aging process of the oil is not the same in all circumstances, because lots of variable factors are involved (environmental, fuel quality…), so the preventive maintenance is normally conservative and usually leads to premature oil changes.
Viscosity is one of the most important properties for a lubricating oil to accomplish its mission.
Experimental Magnetoelastic materials display a coupling between their magnetic and elastic properties.

Influence of these factors were shown by force-displacement, force-time and energy-time diagrams.
In addition to the mentioned researches, Lannucci, Willows [3] and Tita et al, performed some numerical analyses by using a material model which can demonstrate the reduction in the properties of composite materials.
Effect of changes in the shape of impactors and its effect on impact properties of a composite were assessed by Mitrevski and his contributors [4].
It was observed in the previous section that rise in curvature for plate with 3 mm thickness coincided with ascent of maximum force but for thick plate 20 mm, curvature factor does not affect significantly in amount of maximum force.

A critical factor affecting the performance and reliability of KTP in laser system is the quality of the resulting machined surface.
In a previous study, the physical and chemical properties of KTP are discussed in detail, but the machining characters are seldom involved.
On the Lapping Process In the lapping process, the workmaterial is removed by the mechanical and chemical actions between abrasives, workmaterial and environments (water or air).
The properties of lapping pad and abrasives are the essential factors to ensure the super-smooth surface.
It can be concluded from this study that: The mechanical action of abrasives includes rolling and micro cutting in lapping process of KTP.

HIP helps in eliminating porosity, thus enhancing the mechanical properties of the alloys [11].
However, it has been observed that factors such as lamellar spacing and lamellar colony size significantly impact mechanical performance [10, 13]. 2 Materials and Experimental Procedures 2.1 Material and Processing.
Moreover, these microcracks were also observed within lamellar colonies, affecting those identified with the contrast corresponding to the γ phase.

Effect of heat treatment on microstructures and mechanical properties in a full lamellar TiAl alloy.

Due to its high strength to weight ratio and high corrosion resistance properties, it is widely used in aerospace industries and military applications as well as in biomedical implants.
Their low thermal conductivity property reduces heat dissipation capability.
They concluded that the most important characteristics of powders affecting the EDM performance are particle size, particle concentration, particle density, electrical resistivity and thermal conductivity.
CNTs have remarkable properties, such as very high electrical and thermal conductivity, strength, stiffness, and toughness.

The degree of dispersion of aluminosilicate and silica components is one of the important factors in the "mineral component - alkaline grout" system [6-9].
The obtained dependences of the specific surface area of mineral powders on the duration of fine grinding allowed us to establish that the grinding process is rather laborious and is determined by various factors.

One of the key issues for work rolls is the surface roughness which affects the rolling stability and surface finish of the strip.
The refining of grains inside the structure can improve the mechanical properties of the roll, and an increase of carbide can increase the surface hardness and abradability of the roll.
It reveals that the major wear of the roll is mechanical wear.
The result shows that the main factor of roll wear is adhesive.

Physical and electrochemical properties of that membranes were investigated.
In the development of new membranes, functionalisation of a preformed polymer material offers many advantages, in particular with respect to the mechanical properties of the matrix material.
Mechanical properties were measured with a testing machine INSTRON 6025/5500E, using a programmed elongation rate of 2 mm/min (22 ºC, 40 % RH).

The ferroelectric and dielectric properties of the ceramics are characterized by TF analyzer 2000.
The dielectric properties of the BaTiO3-La2O3 were measured at room temperature as a function of the applied voltage.
Besides, the percentage of the la2o3-doped influenced the size of the ceramics, the structure of the crystal and the defects are also the key factors to the high dielectric constant.
That directly affects polarization properties of nanometer powder, therefore, lead to the increase of dielectric constant[14,15].

At the same time, it need to be pointed out that they also have many disadvantages, for example, being buried deep, relatively poor physical properties, a certain heterogeneity, with the bottom water, the high formation pressure and temperature and so on.
The fault sealing property is determined by the physical properties of two sides of fault, and mainly displays on the interfacing conditions of the sandmud of the two sides rock.
Then after determining the deliverability equation factors, we can get the vertical well exponential equation of XX Buried Hill condensate gas reservoir.
Therefore, in order to reduce the risk of gas injection for building gas storage, we need to evaluate comprehensively the influence degree of the above factors on the storage capacity scale.
Because XX buried hill is located at JiZhong Plain, surrounded by a big population, considering the safety factors, it is not suitable to raise the maximum gas storage pressure to exceed the initial formation pressure[12,13].
