Milling is carried out until no further particle size reduction is observed.
The nanocomposites are cured according to the technical data sheet for 75 min at 160 °C and for 120 min at 180°C.
In fact, the additional shrinkage reduction can be explained by the formation of an interphase between filler and epoxy resin [6].
The comparison of the experimental results with the theoretical calculations reveals a higher reduction of the CTE than expected.
The presented results show the reduction of chemical and thermal shrinkage due to the integration of nanoparticles.

The water reduces the peak overpressure outside, which agrees well with the experimental data.
This indicates that the development of shock wave mitigation techniques inside a tunnel is desirable for reduction of the extent of damage inside and outside a tunnel.
Because detailed data on the explosion phenomenon are required to clarify the mitigation mechanism, a numerical simulation would be a useful tool.
Lines and symbols denote data of the present simulations and the previous experiments [7], respectively.
The peak overpressures in the cases of 50-J explosions without water, and 130-J explosion with water shows good agreement, which indicates that the internal energy transfer of 80 J from air to water and the air volume reduction inside a tube directly mitigates the blast wave outside.

This paper established multi-body dynamic model of block-crankshaft system by method of finite element substructure and multi-body dynamics, and carried out the distribution of dynamic stress acting on the crankshaft in a working cycle and on this basis carried out the fatigue strength analysis, then received the fatigue safety coefficient and fatigue life data of each part of the crankshaft.
Finally, the fatigue safety coefficients and fatigue life data of each part of the crankshaft are achieved.
Define the main DOF nodes on the mesh model by the finite element software and conduct the dynamic condensation by substructure reduction method before proceeding the dynamic calculation.
Crankshaft Assembly FE Model Simulation Calculation The dynamic model is established by introducing the FE model file of crankshaft and block and the modal reduction file into dynamics calculation software.
In this study, the measured indicator diagram data obtained at the rated speed of 2300r/min is selected as load boundary condition.

The equilibrium data from adsorption studies fitted well the of Langmuir and Freundlich isotherm models.
As expected, there was reduction in weight due to the lost of volatile matters during rapid heating of carbonization process [6].
The equilibrium data obtained was analyzed using Langmuir and Freundlich isotherms.
From the values of correlation coefficient (R2) shown in Figure 4, both isotherm models gave good fit for the equilibrium data of Ni2+ adsorption on RHAC.
The equilibrium data fitted well with Langmuir and Freundlich isotherm models for the adsorption of Ni2+ on RHAC.

The software has integrated the CNC equipment work process, CAD/CAM, turning/milling program, system control programming, etc, using 3D simulation technology, and a lot of charts, data, explanations and exercises to presentation and training the novice.

This phtenomenon results in the reduction of a pump’s life and efficiency, vibration in framework, and exra noises [1,4,5].
The images showed the reduction of ferrite ratio through depth to surface.
According to the recorded data from table 1, the feed water quality did not have a significant difference from the manufacturer‘s prescribed analysis, except the Electro Conductivity and amount of Calcium and Silicon which were higher than the prescribed analysis.
The data, given in table 2, disclosed the lower corrosion rate for feed water, so resistance to corrosion for this alloy in feed water is in "well" category [8].

Despite the following limitations, difficulties in identifying entry parameters, lack of robustness and reliability in quantitative results and so on, FEM simulation can still be considered as a promising approach to the study of the cutting process, allowing the reduction of the experimental cost.
It can be seen from Fig 3 that water vapor cooling, causes a considerable temperature reduction of tool rake face in cutting process, demonstrates the effectiveness of water vapor cooling.
The simulation results show the same temperature trends with the experimental data [5].
The errors between simulation results and experimental data were from 3% to 12%.
The present simulation results showed a good agreement with the experimental data from other researchers.

Introduction From recently years’ college students’ physical health data, it can be known that their physique is in the drop tendency.
Fig.1 PDCA cycle 2.3 Principle Component Analysis The principle component analysis is a kind of statistic analysis that transforms many variables to a few principle components by applying the data dimensionality reduction technology.
It makes use of the linear combination method, and transforms many indexes into some typical comprehensive indexes based on losing fewer data information.
