The result of hydrogen charging is embrittlement and reduction of metal plasticity [9, 10].
Hydrogen charging leads to reduction of the length of the flow site, sections of uniform and localized deformation.
Which is good, considering the eight-hour working day of the laboratory and allows to obtain the necessary data for the study of the process of hydrogen charging by electrochemical method more effective.
The kinetics of hydrogen charging, according to literary data [1-11] and own tests, depending on the current density, duration of charging, material, used equipment and modes.

The obtained experimental data for dry tests on tool wear, surface roughness and hardness were analyzed and some models were derived, able to predict the above-mentioned variables as function of the cutting parameters.
An analysis was also carried out on the hardness experimental data and a full quadratic model was derived for the surface hardness.
On the other hand, there are important functions of cutting fluids such as the reduction of temperature in cutting zone and the reduction of the friction, the cleaning of tools and workpiece, the transport/evacuation of chips, etc.

It can be shown by some Relevant data that building energy consumption accounts for 20.7% of the total social consumption and HVAC energy consumption accounts for 50%~60% of the building energy consumption[3,4].Therefore, the research on the new energy-saving technology in the HVAC field is very important.
The COPw is around 1.3 and up to 1.8.Its change trend complies with the temperature difference of inlet and outlet in the heat recovery plate exchanger.The COPa+w improves by 50% than the coefficient of performance in the refrigeration mode.The time-varying reduction of COPa leads to its reduction.

Statistical analysis of data Sigmaplot2000 statistical software was used to do relative-analysis and to draw graph, in which each data in the graph was the average of six repeatedly measured values.
There is significant relationship among GST activity of chloroplast, osmotic potential of the seedling leaves and Na2CO3 concentration of culture solution, and among GST activity of chloroplast and O2-. produce rate as well as osmotic potential of seedling leaves, and among GST activity and osmotic potential of culture solution and seedling leaves, and among GST activity of chloroplast and the O2-. produce rate as well as relative electric conductance of the seedling leaves(Fig.9, 10, 11 and Fig.12), which indicates that under the condition of Na2CO3 stress, Na2CO3 stress firstly causes the change of osmotic potential of culture solution of seedlings of P. tenuiflora, then leads to the reduction of osmotic potential of seedling leaves of P. tenuiflora, on one hand, does injury to membrane permeability, on the other hand, the change of osmotic potential of seedling leaves finally affects GST activity of chloroplast and O2-. produce rate.
This does suggest that the function of some plant GSTs might be the reduction of toxic fatty acid hydroperoxides formed during normal cellular metabolism or as a result of oxidative stress[37].

The installation frame which contains the suspension system, ISA and assorted circuits (which include power supply module and sensors data requiring and processing module are not shown for the sake of clarity) is fixed firmly on the base.
The experiment result is shown in table 1: Table.1 The precision differences between single DRLG and within the IMU Temperature state X gyro[°/h] Y gyro[°/h] Z gyro[°/h] 20°C Single DRLG 0.0088 0.0090 0.0093 Within the IMU 0.0113 0.0121 0.0107 -40°C Single DRLG 0.0116 0.0108 0.0094 Within the IMU 0.0131 0.0106 0.0128 65°C Single DRLG 0.0114 0.0098 0.0088 Within the IMU 0.0090 0.0137 0.0112 Range (°/h) 0.0043 0.0047 0.0040 As we can seen in table 1, there are three facts listed below: 1) all three DRLGs are working perfectly; 2) comparing to the precision of single DRLG, degradation is really occurred when the DRLGs are working in the IMU, there are some residues of uncertainty errors such as manufacture mismatch, rubber isolator deformation and so on, but the range is about 0.005°/h and all of the experiment precision are higher than 1.5% °/h; 3) furthermore, considering the data are sampled directly, temperature compensation can be applied by using many mature algorithms which

Further reduction of the electric noise in the QPD output is also required for achieving better measurement resolution.
Improvement of the resolution of pitch angle measurement, reduction of the influences of the thermal drift, etc. will be carried out as future work.

The reduction itself and the reduction rate of ferrostatic pressure play a key role in porosity formation.
The Liquid Motion Intensity (LMI) model provides these kind of data [1,2].

This paper employs the environment statistic data[3.4] of the whole city to compare the IHW generation from 2006 to 2010 (As shown in Table 1, Fig.1 & Fig.2).
IHW generation equivalent and its attenuation coefficient are calculated based on the statistic data discussed in "Chongqing Statistical Annual (2007-2011)".
It is urgent demand for calling clearer production, green technological transformation and energy-saving & emission-reduction process[7].

The average values of the stress-strain data along different directions were used to describe the material behaviors in FEA.
The geometric data on the middle cross section of the profile was defined to verify the accuracy of the FE model.
Note that it is not suggested to apply an over-large thickness compression, as severe compression may cause the wall thickness reduction, the deformation of the shim block as well as higher requirements on the machine capacity.
The compression deformation to the profile thickness should be carefully controlled to provide the bottom/sidewall with a relative uniform stress state but avoid severe reduction of the profile thickness.

., [4] reported Ag nanoparticles and SnO2 films prepared by photo reduction deposition and sol–gel method, respectively, and subsequently deposited onto TiO2 nano tubes (NTs) fabricated by electrochemical anodization.
They have reported the experimental data and the related analysis on the resistance and magneto-resistance of thin films made using a dispersion of these single-crystal nanobelts.
From the transmittance (T) data, the absorption coefficient (a) of these films were calculated in the spectral region of fundamental absorption by the following relation where d is the film thicknesses.
This reduction in the resistivity of thin films is mainly attributed to the increase in the size of the grains as evidenced by the XRD results.
