The uniqueness and impact of this area is that it does not rely on specific material properties to achieve control of light; rather it relies on the engineering of subwavelength scale nano-structures and arrangements that will induce a strong light-matter interaction [1-2].
Such designs have been reported [5] to decrease radiative losses, leading to a cavity with higher Q-factor and improved transmission of the cavity mode.
The resonant mode quality factors (Q) are obtained from the fast-harmonic analysis which yields good accuracy results and high spatial resolutions with relatively short convergences temporal iterations needed.
The calculated Q factors of the cavity design is approximately Q = 2.8×104.
To ensure that the large area region of the doubly perturbative tip actuating mechanism does not affect the nanocavity, the length was chosen to be 1.5µm before linearly tapering the probe structure to a width of 2µm.

Firstly, based on researched mechanical properties of discontinuity, the laws how asperity inclination angles and asperity heights of discontinuity and the mechanical behavior of discontinuity are studied.
The roughness degree is a key factor to affect shear behaviour of discontinuity.
Research on deformation and strength properties of discontinuity has important significant in specific project.
In order to analyze mechanical properties and deformation under condition of different zig-zag shape of discontinuity, the discontinuities with asperity height being 10cm and asperity inclination angle being 10°, 20°, 30° and 45° separately are constituted.

In this investigation, it was found that the inhomogeneity of stress distribution in Cu interconnects is an important factor necessary for understanding textural transformation during annealing.
However, such relationships for the Cu interconnects haven't been firmly established and the driving force which can affect the textural transformation of Cu damascene interconnects during annealing were not clearly identified until now [6, 7].
This can be explained by the fact that the constraints generated by the sidewall increase at layers closer to the trench bottom and may affect the texture development of copper in the trench.
It was also assumed that the copper interconnect has isotropic mechanical properties.
From these results, it can be concluded that the stress distribution across the line depth and width is inhomogeneous in each Cu interconnects line, therefore, the stress state can be a important factor affecting textural evolution of Cu interconnects during annealing.

The data is then used to estimate the Q-value and design the support system.100 Q-values from face mapping were collected and studied and regression analysis was conducted to find out the relevance of the parameters and Q value in conjunction with Support system. 2.4 Mechanical Properties of Shale The mechanical properties of shale are highly variable and are influenced by its mineral composition, degree of compaction, and moisture content.
These properties make shale a complex material for engineering applications, particularly in tunnelling.
The compressive strength is influenced by factors such as mineral composition, degree of weathering, and moisture content.
(v) Design Considerations: Engineering solutions must account for the variability in mechanical properties and the directional nature of shale's strength.
These approaches can potentially capture complex relationships between rock mass properties and support system performance.

From the investigations, it was observed that the cutting tool was mainly the significant parameter affecting surface finish under dry cutting conditions [14].
M2 combines excellent toughness properties with an excellent abrasion resistance because of its relatively low carbon content.
It has superior cooling and lubricating properties and gives a very good surface finish.
It has rust inhibitors to impart anti-rust, anti-corrosive properties and a biocide to prevent bacterial and fungal growth in the emulsion.
All the factors and levels were analyzed and a L18 array was generated.

However, its mechanical and dyeing properties are poor.
The addition of RIFs always causes bothersome fillers aggregation [4], which would cause serious deterioration of mechanical properties.
Therefore, the mechanical properties of the iPP/ROF blends are possibly better than those of RIF- or rubber-modified iPP blends.
The aim of the study was to achieve the uniform dispersion of this novel phenolic ROF powder and then to improve the mechanical and dyeing properties of its blends.
It is always detrimental to the mechanical properties of blend if the filler particles retained this state in the corresponding blends.

But most of these achievements are carried out only considering a certain single factor.
However, practical concrete structures always subject to the combined action of mechanical load and environmental and climatic factors inevitably.
In recent years, many scholars have carried out researches about durability problems of concrete structures under combined actions of mechanical loads and environmental factors in concrete scientific field [5,6].
Results come from tests considering bending load can’t reflect the effects of tensile stress levels on the development of micro-cracks in concrete and the properties of chloride anti-permeability accurately.
This present paper aims to reveal a law of uniaxial tensile load level affectting on micro-damage of concrete and chloride penetration through experimental study. 2.

In the paper, the basic principle and connection influence factors of copper-based shape memory alloy pipe joint were described.
Now, these pipes have possessed many excellent properties such as high resistance to mechanical abrasion, high chemical stability, good heat resistance, good acid resistance, good alkali resistance, salt resistance, water resistance, and anti-microbial erosion, but pipe connection problems have not been solved well yet in China.
The minimum wall thickness of pipe joint is decided by the maximum stress required by the actual environment and the elastic properties of the connecting pipe.
The main performance indexes of the copper-based shape memory alloy pipe joint used in experiment (1) The mechanical properties of the copper-based pipe joint: tensile strength≥700MP a; yield strength≥700MP a; elongation percentage δ5≥30% (2) The memory shrinkage rate of the shape memory alloy pipe joint: ⊿L/L≥1% (3) The gas pressure that can be withstood by the gas pipeline at work: P≥680MPa (4) The oxidation resistance propertyy of pipe joint: 0.00002g/m m2 is weighted for 1h at the air furnace insulation 600℃ (5) The corrosion resistant property of pipe joint: weightlessness at room temperature 20℃ and soaking in 5% HCl is 3h≦0.1008g, 10h≦0.4797g and 20h≦1.0723g Sample production and result analysis The selection of materials For the memory alloy seal pipe joint used in the study, the copper shape memory alloy material smelted in a non-vacuum induction furnace is used.
The pipe joint made of the copper-based shape memory alloy material features excellent compactness, and also this type of material owns high connection strength and good tightness property.

In components with high local residual stresses we have to consider different effects residual stresses may have on the properties of the component.
On the other hand it is assumed that high tensile residual stresses due to welding have a strong negative effect on the strength properties especially under fatigue loading.
The heat input has to be chosen according to recommendations given for the most high strength steels from the producers with the aim to guarantee good material properties.
The reason is, that the heat input can be varied on two different ways that is to say by affecting the cooling velocity and by affecting the grade of restraint because the ratio between the molten or heated zone and the cold material depends strongly on the heat conduction which is affected strongly by the welding speed.

It has unique physical and chemical properties because of its special structure.
This was due to the thermal conductivity of graphene oxide is smaller than that of graphene, and the structural defects occered in the process of oxidation, directly affecting the transfer of heat along the two-dimensional plane .
