Should be noted that all the data used in this paper originate from the Beijing Statistical Yearbook of 2011 [2] and the China Energy Statistical Yearbook of 2011[4].
Analyzing the energy issue by the indictor of energy intensity can learn more information about energy consumption than by the absolute quantity indictor, which is also the core indicator of assessing energy saving and emission reduction used by China's government nowadays.
Secondly, according to the previous analysis, currently, Beijing has made certain achievements in energy saving and emission reduction, but it should make more efforts for energy conservation and improve energy efficiency in the next years.

Finally a 2-D fast Fourier transformation data will be in order to compare the results of composite layup Theoretical approach A model was presented by Hsu at al [4], which model decomposes the transmission of a linearly polarized ultrasound wave into orthogonal components through each ply of a laminate.
A complication arises in determining the values and functions of the orientation of transmitter and receiver and a signal reduction factor to be used in the computation of amplitude for many plies.
The first assumption used is that the interface and beam spreading losses are negligible, that is, all a signal reduction factor terms equal one.

Measurement of the gas phase composition by mass spectrometry requires careful positioning of sampling points and a reduction in the sampling pressure.
The tube was then coupled directly to a 0.30 mm heated quartz inert capillary (QIC) fast sampling capillary, which is differentially pumped before the reaction gas passes through a 0.02 mm platinum orifice to the QMS resulting in a final pressure reduction to 2.0x10 -6 Torr to optimize signal.
This, as well as residual nitrogen in the QMS during measurements account for skewing at the lower limits such that correlation between the QMS pressure data and the nitrogen incorporation cannot be fit over the entire range with a linear fit as shown in Fig. 3.

A separation of the peak due to each diffraction plane was achieved through curve fitting of the experimental data.
The reduction of amorphous area resulted in the increase of crystallinity.
The reduction in this peak intensity can be found.

Compared with IPN, the reduction in ESR from P(NIPAAm/HEMA) was attributed to the increase in crosslinking density or polymer mass per unit volume in the hydrogels, which would decrease the available space for water during the swollen state.
The changes of porous microstructure in all IPN could also be responsible for the slight reduction in ESR.
It is important and practical to examine the drug release data from those hydrogels like the body temperature (37°C).

Strong interaction between bedrock and earth core might lead to quite large differential displacement, large shearing stress and a reduction in stress at the bottom of earth core.
Stress reduction might even lead to negative stress in earth core and rock filled shell zone.
Therefore, arrangement and analysis of computation data was focused on the time when dam construction completed and water level reached normal storage level.

From the second cycle onwards, the oxidation and reduction peak currents were increased at 0.20 and 0.00 V (indicated by the arrows in Figure 1).
While the electropolymerization was increased to more than 15 cycles, both the oxidation and the reduction peak currents started to decrease suggesting the formation of electroinactive film.
The data show that there is a gradual increase in CC peak current with an increase in CC concentration and the oxidation peak current of HQ almost constant.

Even the deflection of the acting force from longitudinal axis of the rod only up to 15° results in a significant reduction of its load-bearing capacity (see Fig. 1).
However, the reduction rate of tensile strength of the specimen gradually decreases.
For a more reliable prediction of GFRP reinforcement behaviour, data from specimens of other diameters/types should be supplemented.

The regularities and causes of changes (reduction) indicators of the quality of concrete with combined aggregate.
Structural analysis data with certain reliability allows to establish the influence of certain technological factors on the formation of the structure and properties of products and can provide effective control of production.
The obtained data confirmed the assumption that the presence of hydrate formations of cement stone on the surface of the combined aggregate, close in structure and chemical composition to crystallizing tumors, promotes the formation of strong isomorphic and epitaxial coalitions between calcite carbonate fillers and calcium oxide hydrate due to the proximity of the lattice parameters of these crystals.
