Simulation has been realized on two models with analysis of resulting data.
Simulation has been verified on two proposed models with subsequent analysis of resulting data.
Even if the height of draw piece “B” is by 40 mm bigger, difference in reduction of thickness in critical areas between both models is insignificant.

Based on a roadway project of Dongqu Colliery of Xishan Coal and Electricity Group,using the geological exploration data and on-site research and referring to the theory and engineering experience, the tunnel grouting program for marl was worked out and it was revised the program in the construction.
According to the drilling data, the sedimentary cycle in general the formation is brecciated limestone, marl and brecciated limestone.
(2)In order to facilitate the infiltration of the grout in the crack path, advanced and reasonablely arrangement of reduction of artesian water is available

The obtained spectroscopic data has been correlated with the conductivity performance of hexanoyl chitosan-based polymer electrolyte.
This in turn results in the reduction of ion mobility which leads to the decline in conductivity.

Through the comparison of experimental phenomena analysis, the general rules of coefficient stiffness and energy dissipation capacities were obtained, and the corresponding theories could be analyzed with the experimental data.
But the study of Topcu I.B[1],Margaret M[2], Jianzhuang Xiao [3] and other scholars all showed the recycled aggregate with large porosity, compaction, aggregate strength low defects, the test blocks proved that it existed the different reduction phenomenon on the compressive strength, shear strength, and other mechanical performance index.

In order to meet the demand on the miniaturization and manufacturing cost reduction of
the multilayer ceramic capacitors we have developed a nano-BaTiO3-based non-reducible dielectric
material through a soft chemical route.
It is 30 nm for the powder calcined at 850℃ for 2h.The XRD data of the ceramics of nonreducible BaTiO3-based dielectric obtained after 1200°C sintering show that the diffraction peaks become much sharper.

Reduction in adhesive remnant is
likely due to the higher bonding of adhesive resin to granules.
The Weibull statistics were useful to relate survival in clinical trials to the data obtained from laboratory tests[5, 6, 7].

The zeolite with 7.5 g of sorbent dose and activated at 225oC for 3 h has a high salinity reduction of
3.2 ppt and reduction efficiency of 4.9%.
This decrease arise from the reduction of the pores created by the empty sites of the evaporated water and the same residues of PVA as well as the combusted residual organics.
Furthermore from XRD data, zeolite contains 59.30% SiO2.
The melting continues until the pores become filled, causing a reduction in the porosity [33].
For all samples, the decrease of the permeate flux with time is because of the reduction of the pore sizes by blocking the internal pore connection [35] and adsorption of impurity droplets from the non-sugar ingredients.

Currently, energy saving and consumption reduction has been a crucial task the domestic people are facing with.
In this paper, we classified new wall material and thermal insulation material, analyzed the performance, feature and application of such materials, selected typical foam concrete and slurry insulation material and analyzed their thermal properties and technology parameters and so on, to present the development trend and direction of energy saving building material, to provide valid scientific data to relevant building energy saving management units, design units and construction units, to play a positive guiding role in improving the application level of new energy saving building material and promoting new energy saving building material of high quality.
In use, slurry insulation material should pay attention to the following test data, apparent density, bonding strength, thermal conductivity, volume shrinkage, softening coefficient, water absorption, fireproof performance, content of asbestos and so on.

Figure1: Relationship between the different birthday day m and probability of at least two people share the same birthday (evenly distributed)
Monte Carlo simulation
Take 3 non-uniform distribution of the birthday data as example.
Simulation steps: (1) Get the given birthday data’s distribution law
Moreover, Monte Carlo simulation combined with variance reduction technology can make the same birthday probability more accurate.
