Using nanoindentation to measure material mechanical properties has been a pioneering application of nanotechnology in materials science and engineering.
Cement-based materials' local mechanical properties can now be measured at the nanoscale with nanoindentation [11], and researchers have recently used a "Triboindenter".
Many properties of cement, including as mechanical and transport properties, creep, and shrinkage, need a thorough understanding of the interplay of cement phases with water.

Al 6061 alloy is one of the non-ferrous metals which have properties of light; the power level is roughly equal to mild steel, good corrosion resistance, electrical conductivity and good heat and easily formed through the process of forming and machining [4].
The four end mill parameters (control factors) are type of milling operation, spindle speed, feed rate and depth of cut.
When the range of the series is too large or the optimal value of a quality characteristic is too enormous, it will cause the influence of some factors to be ignored.
Finally, with the application of Analysis of Variance (ANOVA), significant factors in this quality index and their contribution percentage for total variation in MPI can be obtained.

The quality of refrigerator inner liner not only affected by each structural characteristic, but also affected by mutual coupling of structural characteristics.
Table 3 lists the factors and factor levels selected in the main experiment.
And those most significant factors could be disclosed basing on the result of range analysis.

Experimental results using the proposed control strategy show better performance and robust properties than the ordinary Fuzzy-PID.
Since Fr is affected by various factors such as wheel friction, vehicle velocity, vehicle load and also other friction, it is regarded as random disturbance in the actual project.
It is used to analyze the dependencies among the properties of the information decision system and the necessity of a data value without a priori knowledge.
V is the property values.
In order to protect the control system hardware and mechanical properties of the vehicle, two limit switches are installed at both sides of the front wheels.

Because this resin has good adhesive, excellent chemical resistance and good thermal properties [1-3], which was duo to their rigid backbone structure and high cross-linking density.
Meanwhile, the thermal properties were also affected after the modification [8].

First, sample with residual stress of shot peening were detected, material properties change with residual stress was analyzed.
Material Characteristics of Cold Deformation Strengthening In order to facilitate the discussion, focuses on the properties of the materials after shot peening.
Changes in Material Properties.
After the shot peening treatment, the material properties of the surface layer material is defferent with the material properties of the core material.
The shot peening residual stresses affects the size of the mean stress, the size of the mean stress also affects the size of the fatigue strength[1].

One of the intrinsic HPDL (High Power Diode Laser) properties is the rectangular beam shape, which can be profitably used in welding of large polymer parts.
Beyond reduced handling costs, the residual mechanical properties of the weld governed by the thermal cycle can be controlled by the pulse shape and are no longer constrained by the welding speed.
In determining the conditions of the process should take into account several important factors, including the following: the beam energy, absorption differences between the cast of aluminium alloys, laser scan rate.

The improved measures, which is under the premise of not affecting power performance and economic efficiency of IC engine, combining the emission process of IC engine was presented, it needs some measures to improve the quality of biodiesel and the system of IC engine to control the emission of the harmful substances, in this way the problem of energy shortage and environmental pollution can be ameliorated.
Introduction Petroleum resource is an important factor that the development of human society relays on, which is related to national economic stability and national security.
Factors affecting cetane number of biodiesel including two parts: one is that cetane number of animal oil methyl ester is higher than that of vegetable oil methyl esters; the other is that long carbon chain contributes to the improvement of cetane number, the less unsaturated double bonds, the higher the cetane number [18].
Depressants can improve the cold flow properties of biodiesel, making the engine work at low temperature.

It should be noted that the reliability and durability of the reactor pressure vessel and its internals under operating conditions is determined not only by the average level of physical and mechanical properties of the steel, but also by the homogeneity of these properties in the entire volume of metallurgical blanks [3-5].
At the same time, there is an acute problem of ensuring the homogeneity of properties in the production of billets from large ingots.
This can affect the technological ductility of steel, as well as have a significant impact on the formation of the grain structure and mechanical properties [10,11].
