Theoretically, CNTs based nanocomposites may have very high mechanical properties with very low weight.
Unfortunately, like in every composite material also in nanocomposites the high mechanical properties of reinforcements are only partially transferred to overall composite's mechanical properties.
Their specific mechanical and electronic properties make them useful for future high strength/modulus materials and nanodevices.

Interproximal cleaning is an important form of oral self-care habits, considering such areas of the dentition are easily affected by caries.
AuNPs have many interesting properties, such as ease of preparation and modification, biocompatible, and nontoxic to human cells.[10,11] Previous study showed that small-sized AuNPs (22-52 nm) have an increase likelihood to penetrate through bacterial cell membrane.
This also can be described that the particle size and surface charge are ones of the important factors to improve the antibacterial property of nanomaterials.[23] The smaller particles with the larger surface area can adhere more to bacterial membrane, thus inhibiting bacterial growth.[24] As regarding incorporated dental floss, previous studies reported the fluoride impregnated dental floss by Chaet et al.[25] and Keene et al.[26] but there have been no report involving nanoparticles impregnated dental floss.
Further study could focus on associated toxicity, comparison with physical and mechanical properties to similar products in the market.
This information can serve for future development of dental floss product with antimicrobial properties and mechanical properties.

To carry out the simulation experiment, the results show that the proposed controller can guarantee that the system has better dynamic and static properties, error convergence rate is greatly improved.
In order to achieve the Potter diagram frequency, that in the middle and low frequency zero phase shift zero gain, high frequency amplitude fast decay, restrain the resonance peak value, reaching zero phase shift effect, system uses Notch functions and two order low pass filter superimposed structure , the Notch function expression for: The Notch function has periodic notch characteristics, its specific frequency attenuation rate is far greater than the 2 order filter, and on the adjacent frequency gain affects less than 2 order filter, if the coefficient is appropriate, the function also has a zero phase shift characteristic.
In the middle and low band gain of 0, the phase difference is zero, so that the system has better stability and convergence; High frequency phase difference is existent, but high frequency signal attenuation is very large, does not affect system performance.
After system input rectifier, using unidirectional half-bridge inverter output structure, power tube using IGBT, switching frequency 20kHz, ignore rectifying filtering, inverse peak voltage network so that can absorption secondary factors， system parameters as the input AC voltage 220V.

On the basis of the analysis of the periodic multilayer dielectric high-reflective film and the beam splitter, to meet the special requirements for the filter film of the optical prismatic system, this article takes some related research on the optical properties of materials, coating design, technological parameters and so on, including two highlights: 1)the design problem of wide band, high precision high-reflective film and the beam splitter;2)the absorption problem of multilayer dielectric film.
In the process of film design system, the selection of coating materials is based on technical requirements and material characteristics (such as transparency, dispersion and absorption characteristics of materials, mechanical stability and chemical stability, etc.) to be comprehensively considered.
Therefore, in the condition of the film not affecting the center wavelength of reflectance, we add MgF2 of a half of design wavelength physical thickness to broaden the zone of reflections, meanwhile in order to make beam correspond to the require of 2:1, we optimize the film system further, and finally the structure is below:Sub|1.79A1.01H1.10L1.08H0.33L 0.35H2.12L|Sub, in which H-Ti3O5, L-SiO2, A- MgF2.
By the way, we use Kaufman ion beam source as assistance during the deposition, it can improve the film’s intensity and enhance the Optical and mechanical properties of the film[15].
After analysis the main factors are as follows: 1）the Photoelectric extreme method which is used to control the extreme value will introduce into a certain human error; 2)In the experimental process, the value of the tooling will change along with the change of the technological parameter, and the value of the tooling also can directly affect the actual thickness of the coating system, leading to a certain thickness error and then influencing the transmittance of the film; 3)there still exists a weak membrane layer absorption and the scattering phenomenon.

However, this PMF is applied directly to the mobile vacancies in contrast to mechanical stresses.
Of these, it might be reasonable to assume that the geometric factor g and l will not be affected by the presence of microwaves because it is determined by crystal structures of the material.
Thus, the jump frequency (n) is the only one possibly affected by microwaves.

The sulfates in the complex activator could stimulate the activity and promote hydration of cement and fly ash had significant effected in the early time[4].However,joined too much will affect the strength of the cementing material.Actually,1.5% of complex activator could be added.The proper proportion was that the content of Cement,Fly ash,silica fume and complex activator was78.5%,12%,8%and1.5%.According to the proper proportion ,the mechanical property of cementing material were shown in Table 5.

Introduction Titanium and its alloys have been widely used for aerospace, medical, and other applications because of their excellent properties such as high specific strength, good heat resistance and corrosion resistance properties.
Non-uniform green density distribution, coarse particle, gravity and friction are some of the factors that may influence on the distortion of the sintered parts [4].
The average oxygen content was 0.278 mass % after sintering, which is higher than that of the initial powder (0.115 mass %) However, this oxygen content level does not affect the mechanical properties [10].

As a result, most mathematical modeling approaches often result in predictive models with unknown factors, so that these models are of little practical use.
Further, the material removed by a single particle can be estimated in terms of the target material properties (fracture toughness, hardness, flow strength etc.) and particle properties represented by the velocity, density, shape and size of a particle [12].
However, it is not realistic to include all material properties in modeling the AWJ cutting performance.
Further, water pressure, P, is related to the water and particle velocity in a jet and affects material removal and particle flow direction.
To consider this effect, a proportionality factor, k, is introduced which can be determined from experimental data.
