As the result, Pt/C is used extensively in PEMFCs as an electrocatalyst to enhance the activity of oxygen reduction reaction (ORR) [2].
For example, Micoud et al [9] synthesized Pt/WOx catalyst by impregnation reduction method.
The data were collected from 20o to 80o in 2θ scale.

Natural fibres can contribute positively to sustainability and cost reduction of many products (Bonnet-Masimbert et Al., 2020).
Dog bone-shaped samples (80 x 40 x 40 mm) are used, with an area reduction at both sides of the sample of (40 x 10 x 40 mm), rounded off at the corners.
In addition, a reduction in strength is observed for higher percentages of fibres in a mixture.
Substituting local data for overseas life cycle inventories – a case study of concrete products in Hong Kong.

Our experimental data clearly show that in the early stage, the deformation is not homogeneous within the sample, indicating that significant softening occurred.
Thus interphase boundaries play a critical role in the grain size reduction mechanism.

The computation results are in good agreement with the experimental data.
Experiment model To reduction model, make an assumption as the minimum explosive velocity is a constant on the border.

Using data associated with the traffic parameter for congestion and non congestion, an incremental SA-PC method is trained to detect whether traffic congestion occur or not.
Under travel time uncertainty, it is found from several empirical studies that road users (or travelers) make their route choices, not only dependent on travel time saving, but also on reduction of travel time variability [2-4].

The measured data suggests that this wind farm is uncompetitive.
The real capacity factor (CFR) determined using measured data is 14.90%.
Research Methodology Data Collection Operational data of the two turbines was collected from 1st May 2009 to 30th April 2010.
The data was taken for only one year.
However, these tests rely on the accuracy of the manufacturers’ data.

The data collected in this research provide reference for the optimum mix proportion of the adulteration quantity of the concrete admixture.

These data are derived from the version engineering with high engineering significance.
The paper refers to the experimental data from NASA Metrics Data Program.
Defect pattern is summarized from historical defect data, so it is scientific and reality.
To introduce metrics into the knowledge base is a strong complement to software defects data.
A pattern recognition approach for software engineering data analysis.

One can choose the isotherm that fits the experimental data best.
Elevated system pressure when is isothermal, bed adsorption capacity increase, the gas adsorbed, otherwise the system pressure drops, and a corresponding reduction in its adsorption capacity, adsorbent was desorbed for regeneration, and get gas products at the same time.
The reason for considering ethanol-loaded GAC desorption under vacuum condition is that because vacuum microwave desorption of ethanol-loaded GAC has obvious advantages when compared to microwave desorption of ethanol-loaded GAC under N2 condition and advantages listed as follows: 1) High concentrations of alcohol, when stress reduction, ethanol in gas phase increase.

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.
