Finally combined with the data, we predict the future 30 years and 2050 years of China's total population, predicting the birth rate, the mortality rate, the natural population growth rate.
Using MATLAB software and MathCAD software and based on collecting data, we calculate the value of each statistic from 2001 to 2005.
The level of human health raising leads to reduction of natural mortality rate.

Atmospheric pressure cold plasmas have received increased attention recently because of several emerging applications such as in material processing, aerodynamics (drag reduction, shock wave mitigation) [2, 3], bio-medicine, and radar communications (absorption and reflection of microwaves).
Fig. 3 Temperature distribution.Numerical simulation of plasma jet The calculation results of the plasma jet along the jet centerline are compared with calculating data in paper [8], shown in Fig. 4.
(a) (b) Fig. 4 a and b are velocity and temperature distribution along the jet centerline respectively It can be seen from Fig. 4 that the simulation results by D2Q9 model agree with the calculating data and the distribution trend of the velocity and the temperature distribution along the jet centerline are almost as same as in paper [8], respectively.

The Ag content being close to the detection limit it is given as relative content deduced by SIMS (a) while XPS data are reported for Cu (b).
Conclusions The greater efficiency of Ag is demonstrated by the fact that Ag-TiO2 nanocomposite coatings become bactericidal, i.e. a reduction of approximately 7 log CFU (colony forming units) for Ag content close to only 1 at. % while a comparable efficiency requires about 3.5 at. %. of Cu.
Squares and triangles in (a) are SIMS and EDS data measured on 20 and 400 nm thick films, respectively.

Values of lattice parameters from the X-ray diffraction data can be manipulated to get values of strain along the c-axis (εzz) by using the following Eq 2 : Eq. 2 where c is the lattice parameter of the strained ZnO films calculated from X-ray diffraction data and co (5.207) is the unstrained lattice parameter of ZnO.
The reduction of in the length and diameter of the ZnO nanostructure was due to dissolution of ZnO to form Zn2+ ions, followed by subsequent redeposition of Zn2+ ions as ZnO upon extended temperature HWT exposure.

This, of course, leads to a reduction in the acquisition rate of experimental data down to ~30 events per second.
However, the estimation of the concentration of the vacancy-type radiation defects based on the positron lifetime spectroscopy data (see below) gives a much lower value, ~1017 cm−3.

PHEVs can get about 50% reduction in fuel costs compared with the traditional HEVs.
The models of engine and motor are designed according to their test data.
Engine power, fuel consumption and emissions at specified speed and load can be calculated via data interpolation.

The reflectance data of ZnO, Ag-ZnO and Cu-ZnO nanoparticles are presented in terms of kubelka constant.
Impedance data (Table.2) are analysed in terms of Niquist plots which provide the ohmic and charge transfer resistances of the semiconductors.

The contact angle (CA) of distilled water was measured at room temperature using an optical device OCA 15 Pro (Data Physics).
According to the data obtained the phosphating and anodizing methods significantly decreases the values of CA up to 2 ± 1°.
According to studies anodizing allows to obtain more resistant to moisture adhesive joints compared with chemical treatment: the maximum reduction in strength values was 25.3% and 39.3% of the initial strength, respectively.

After the reduction, the temperature was raised to 650℃ under flowing Ar atmosphere.
The data indicates that the top surface of AAO template with pore diameters 25nm has a strong catalytic property.
The above literatures and statistical data suggest that when an AAO template itself was used for CNT growth, a competitive catalytic carbon deposition between on the top surface of AAO template and in the pores was involved.
