Through the airfoil surface boundary layer is divided into a viscous sublayer, buffer layer and the layer data rate, the actual flow, the viscous sublayer of the gas velocity is very different, the velocity gradient, the viscous force is relatively large.
Numerical simulation on drag reduction of revolution body through bionic riblet surface[J].

The data obtained from the analysis of particle size distribution indicates a size distribution for granules in the range from 0.08 to 0.3mm for the HA-Zn powder.
The narrowing of diffraction line can be explained both by the increase of the crystallites size (table 1) and to a reduction of the residual stress level due to the heat treatment.

The quality data of three kinds of water were shown in Table 1.
Off hard pretreatment removes most of the calcium and magnesium ions, and inorganic fouling on RO membrane surface is relative reduction, so the range of flux attenuation is lesser than direct ultrafiltration.

Introduction Following the trend for the reduction of greenhouse gas emissions and fuel consumption, automotive manufacturers are continually looking at ways to reduce vehicle weight.
[3] Technical Data Sheet: Anticorodal-121 AA 6016 (Alcan Rolled Products Automotive, Switzerland, 2002) [4] M.

Many researchers agree that the strength of material enhanced by increasing Si ratio [7, 8], but after getting optimum compressive strength additional silica in the matrix causes reduction in strength.
Table 1: XRF Data Analysis of Fly Ash.

(1) In order to measure data more intuitively and easily, we can define the ratio of depth to diameter K, to show the taper simply : (2) So, (3) In order to avoid accidental error caused by instability of the processing equipment, 5 holes samples were evaluated in each process and average is taken out of them.
When the laser processes the bottom of the workpiece, because of the overflow of the gasified material, the laser energy will rapidly decay, leading to the reduction of the processing efficiency.

The microscopic examinations include thermal, chemical, kinetics, and mineral data.
In flameless combustion technique, due to oxygen concentration reduction in the reaction zone, combustion spreads over a large volume, peak temperature decreases, heat flux and thermal efficiency increase and stable combustion is observed.

So increase in the amount of MOS could significantly reduce the oxygen release rate; (2) ORCs with 5% and 10% MOS made dramatic reduction in initial oxygen release rate at the first day by 50%, even by 90%; (3) with the ongoing of the oxygen-releasing process, the oxygen release rate gradually recovered to 85% and 60%.

The EIS data can be analyzed by the Nyquist diagram and Bode phase plot.
The increase of Voc in the low dye-loading range was plausibly attributed to a reduction in exposed TiO2 surface with increasing dye coverage, since the exposed sites are favorable routes for electron recombination between injected electrons and triiodide in electrolyte.

Variance analysis Design Expert 7.5 software was used for data analysis and processing.
Meanwhile, corresponding P values of A-space between membranes, B-aeration rate, C-the sludge concentration were less than 0.05 in the model, indicating that all 3 factors have important influence on sludge reduction. 3.2.
