As in the case of aspect ratio, the adverse aerodynamic effects associated with increasing taper are counteracted by a reduction in wing mass due to the movement of the centre of pressure to the inboard sections and therefore a trade-off study is necessary to confirm or otherwise the choice of taper ratio.
Traditionally, wing section data has been presented in a series of curves which show the principal aerodynamic characteristics (lift coefficient, CL, drag coefficient, CD, and aerodynamic moment coefficient, CM) as shown in Fig. 2.

In order to compare with the vibration intensity under different rolling mill situation, different rolling speeds (set speed to 50%, 75%, 100%), different emulsion concentrations (low, medium and high concentration), different rolling specifications (select thickness finished product 0.4 to 2 mm) are selected as the test conditions. 2.2 Manifestations of strip chatter marks Some data indicate that there are two kinds of waves on the strip surface chatter of the strip related with vibration, one called thick wave, and the other called shape wave.
Vibration of roll system directly effect on the the strip surface , and make the strip surface generate chatter marks.In actual production, roll system vibration not only makes strip generate chatter marks, but also makes roll system itself, particularly backup rollers, generate chatter marks.If not exchange roll timely . 4 Chatter mark suppression measures For detailed analysising and processing all test data in duty cycle of backup rollers,confirmed by filed maintenance results, it is could be determined that HC cold-rolled temper mill system generates self-excited vibration during skin pass process,so chatter mark is generated on strip steel.
Reduction of chatter marks during the temper rolling of steel strips.

The value of the curve slope is negative and small, so traditional temperature reduction or increase method is not suitable for growing NNSH crystal.
The determination of unit cell and the diffraction data collection were performed on an Enraf-Nonius CAD4 diffractometer with graphite monochromatized Mo Ka radiation (λ=0.71037Å) by using the ω-2θ scan mode in range 2.84º<θ<39.97.
NNSH crystal belongs to monoclinic space group P21/c, a=5.5374(9) Å, b=8.2022(13) Å, c=11.0520(18) Å, β=100.5010(10)º, v=493.56(14)Å3, z=2, Dc=2.482g·cm-3, which accords with the data reported by D.Stoilova[4], et but exacter.

In the secondary treatment system of the municipal sewage plants, the energy consumption of aeration takes up 50% of the total energy consumption, so the reduction of the energy consumption of the aeration system is the key for energy-saving of the whole plant.
According to the test data, when the system runs at the best working condition, the average removal rate of COD stands at 77.81%, with the highest removal rate of 84.00% and the lowest of 72.33%.
We can divide COD in the sewage into two parts according to biodegradability: biodegradable COD (CODB) and COD (CODNB) that can not be degraded. 27 groups of data of B/C value of the inflow and the effluent can be seen in Figure 1, the average value is 0.49 and 0.29 respectively, with the minimum of 0.40 and the maximum of 0.60 for inflow; and 0.14 and 0.43 for effluent.

A dynamic signal analyzer, produced by Data Physics Corporation with model number SignalCalc430, was used for the fast Fourier transformation of the acquired analog signals from the accelerometer.
The vibration data of the test beam is acquired by the accelerometer and sent to the dynamic signal analyzer.
But the relative reduction is variable for different excitation frequency.

It can complete many works, such as data acquisition and processing, communication protocol and control of the node, etc.
In the RF circuit(as Fig.3 below), two inductances are in series and connect to a balun LDB2120402C-001 which can support the better bandwidth and the less performance reduction.
In order to assure data be transmitted correctly, the frames are sent in CSMA-CA mode, and the answer signal is adopted. 4 Conclusions Conventional vibrating wire sensor should be use together with frequency meter, and such system has the feature of high accuracy.

For this calculation model, it can be got by calculating with geological data and the design drawings: Taken the pile cap bottom as maximum scour line, l0=0m, elastic modulus of concrete , auxiliary pier pile base:; pylon pile foundation:, put the data into the formula 1, it can be obtained respectively: embedded depth of auxiliary pier pile H=5.44m; embedded depth of main tower pile H=11.76m, both in the range of 3 to 5 times of the diameter, while modeling take embedded depth of auxiliary pier pile H=6m; embedded depth of main tower pile H=12m.
Conclusion Through analysis self-anchored cable-stayed suspension bridge of two calculation modes between consolidation bottom of tower and considering pile-soil-structure interaction, we can obtained the following conclusions: (1) The integral rigidity of structure could be reduced and natural vibration period be extended by pile-soil-structure interaction which has the most influence to the first period; (2) Because of reduction of integral rigidity of structure, while longitudinal seismic inputting, longitudinal displacement of middle main span and main tower top increase obviously; the bending moment at tower bottom and pier bottom both decrease significantly, a 47% decreasing amplitude.

The mathematical model is established, combined with theoretical analysis and observational data.
Experimental data shows the fractal dimension of the crack increases with the increasing number of stress cycles initially, and decreases gradually as it reaches a certain value.
Due to bending and the reduction of the degree of its change, the covering dimension decreases.

The DSR data of asphalt binders, obtained by means of frequency sweeps at different temperatures under linear viscoelastic conditions, were horizontally shifted to form master curves at the selected reference temperature by using the TTSP.
The rheological changes for the base asphalt (#1) following RTFO aging as seen in Fig. 2 display an increase in complex modulus and a reduction in phase angle.
Conclusions Frequency sweep data from DSR testing over a wider range of frequencies were horizontally shifted to construct master curves of complex modulus and phase angle for SBS modified asphalts and base asphalt by means of the TTSP.

The supervisor establishes supervision executive detailed rules according to laws and regulations relevant to the country, ordinances, project contract documents and technological data.
It need to examine approaching materials, and deeply understanding management goals of all kinds of nodes in the green construction, at the same time, recording, collecting and clearing up the information data, in order to formulate relative measures of organization, management and technology.
In the process of construction, supply chain is throughout, and it is one of the significant ways implement energy saving and emission reduction in the process of green construction.
