Beijing a.37264565@qq.com Key words: Asphalt Mixture; High Temperature Stability;Impact Factors Abstract: Rutting is one of the most hazardous damage form of asphalt pavement.But,owing to itself inherent in the viscoelastic characteristics of asphalt mixture,the diversity of factors influencing the high temperature of asphalt pavement anti-rutting performance and The complexity of rut formation,this three reasons make ruts become a worldwide problem.Starting from the mixture, This article analyzed the influence factors of the rutting resistance of asphalt mixture at high temperature.For asphalt mixture, through the experimental data, the research status at home and abroad, from the type of asphalt, asphalt content, grading of aggregates and air voids four aspects analysis and study the influence factors of the stability of asphalt mixture at high temperature. 0.

Depth extraction using 2,662 depth sample data.
The depth data will be divided into two, data used for depth extraction modeling samples and data used for accuracy testing.
The selection was done by random sampling using 1,000 data, 2,000 data, 2,400 data, and 4,000 data.
The depth extraction model data used is obtained from the overall data as much as ± 25% of the data.

However, most of approaches estimate CPU power consumption only from CMOS power consumption data and CPU frequency.
The dynamic power is considered as the power consumption when a processor is processing data in a certain time period.
The Hardware Power Consumption Measurement of Modern Multi-core Processors In order to measure the power consumption of a PSU, the high accuracy Extech Power Analyzer/Data Logger 380801 power meter is used as Figure 3.

The resulting data consists of the tensile strength, microstructure (including the size of grain as well as the morphology of the β phase that were precipitated), and distribution of hardness on the weld’s cross-section.
The use of aluminum and its alloys in automotive structures, aircraft, and electrical elements has increased due to the efficiency and significant reduction in structural weight.
While this method has been the subject of research for some time, comprehensive data regarding the welding process and the specific effects of heat treatment on 6061 aluminum alloy friction stir welds remain limited.
According to the results for the test of tensile (displayed in Figure 6b), the higher the aging temperature, the higher the tensile strength and the lower the elongation, which is also consistent with the resulting data of the hardness test.

From the data, highest efficiency was obtained from sample deposited at 3500C which is 0.114493% followed by 0.007912%, 0.000374%, 0.000335%, 0.000001%.
The reduction in sp3 ratio reduce the dangling bond [11] and from the electrical and optical properties it was observed that at higher temperature, the sp3 ratio reduce, based on the incresing conductivity and reduction in optical band gap energy.
This gives rigid explaination on the cause of reduction in efficiency as temperature increase.

Historical data provided by tank manufacturers, shows that within the range of dimensions used in this investigation, the failure is dominated by buckling [4].
Results shows that the tank length and the buckling pressure appears to have a close to linear relationship up to a tank length of approximately 3.6m after which slope changes and the rate of reduction in buckling pressure becomes less sensitive to any further increase in length of the tank.
It is shown that the reduction of 83% in rib-spacing lead to 200% increase in buckling pressure, and the highest appears to be at m.
A reduction in the ribbed tank’s diameter from 3.2 to 1m (70%) shows an increase in buckling pressure from 8.5 to 36.2kPa (425%).

This is, however, difficult to achieve in constitutive model using only two scalar damage indicators for tensile and compressive behavior, due to the lack of experimental data.
On the other hand, it is also observed that the material deterioration leads to a decrease in the elementary area of resistance and hence the reduction of the material strength, resulting in the indirect coupling between damage and plasticity.
This implicit coupling characterizes the strength reduction due to the material deterioration and is equivalent to introducing effective instead of nominal stress into the yield function [15].
The coupled damage-plasticity model is intended to capture important features of the material behavior such as the strength reduction, stiffness degradation, and permanent deformation; all of which occurs in both tension and compression.

In accordance with the 2011 data, assuming the limestone are all used for the cement production and are consumed about 20 million tons per year, 20 years later China's cement industry will be difficult to sustain.2)The impact of cement industry on the environmental load, including CO2, dust, SO2 and NOx, industrial waste emissions and noise pollution source load is severe, especially on the dust (soot) pollution, accounting for 40% of the emissions of industrial dust and ranking first in all kinds of industry[2].
Applying wastes as the secondary fuel of cement kiln had several advantages including the emission reduction of CO2, SOx, NOx and methane due to burning coals, less expense of waste disposal, and economic benefits of the cement plants.
After solid-liquid separation, NaOH and NaSH were added into filtrate to adjust pH value and oxidation-reduction potential.
With the purpose to achieve the safe treatment, recycle, reduction socialization and industrialization of urban waste disposal, development of eco-cement become an important part of eco-city construction and strategy of sustainable development.

But the direct result that the shearing force acts on flocs results in grain diameter reduction of flocs and broadening the distribution of grain diameter, which would make the filtering and subsiding rate of flocs to decline distinctly.
This indicates that reduction the shearing force sustained by flocculant should also be taken into account while considering reduction of the shearing force sustained by flocs.
It can be observed from the experimental data in Table 1 that as compared with jar testing method C, the subsidence rate of flocs conducted with controlled flocculation process A has raised by 47% averagely, the filtering rate of fermentation broth has raised by 65% averagely, the loss rate of lincomycin and micronomicin in the filtrate is no much difference, and both are under 5%.

Reduction of liquation is possible by providing accelerated solidification of the casting [12].
Taking into account the peculiarities of the process of casting copper alloys in the chill mold, the coating must withstand significant temperature influences, as well as ensure a reduction in the coefficient of friction of the forming surface with the poured melt.
