Introduction Deterioration of the reinforcement structure corrosion caused by carbonization corrosion has been paid attention to by some scholars and a number of research data and results have been got [1,2,3].
(7) μ——shear capacity reduction factor considering the reinforcement corrosion in the beam, which can be described as Eq. 8:
Then, based on the vehicle load survey data measured in Luogang Section of No.107 National Highway, and the basic theory of probability and statistics, the parameters such as gross vehicle weight, axle load, wheelbase, vehicle spacing and so on, are statistically studied[10].

Introduction Energy conservation and emission reduction is the technology focus in the environmental protection field.
The datas are substituted in equation(9), and calculated result shows that the minimum system desorption energy consumption is 3.10GJ/(t CO2) when the mass concentration of CO2 is 40%.
Look up numerical data and we can see that =472.39kJ/kg,=510.44kJ/kg,and =433.93 kJ/kg.
The datas are substituted in equation(10), (11) , (12) and (13), and calculated result shows that the COP of the lean solution source heat pump is 2.01, and the desorption energy consumption of unit CO2 is 0.96 GJ/(t CO2).

The minimum temperature of the test is -50°C.The loading process and data acquisition are controlled by PC automatically.
Conclusion According to the research results and the experimental data, a description of frozen soils can be obtained.
With the reduction of temperature, the decrease of ice strength compared with the increase of soil strength due to bonding effect, the ratio reduces.

There are overlaps between these types of methods, as well as complementarity, protected space resistive, capacitive and inductive "coupled" noise reduction to harmless [1], thereby reducing the switching overvoltage damage by lightning.
According to the local meteorological data and formulas to calculate the value of N, to determine its level of lightning.
Induced voltage conductors in different ways By formula and chart data, switch lines must not be allowed immediately laid in parallel with other conductors, laid in parallel to ensure that a certain amount of space, if you want to cross with other conductors must ensure vertical laying.

Thus, the analysis of experimental data allows us to assume that the particles is SnO2 and PbO, while the nanowhiskers growing at their surface consist of SnPb2O4 mixed oxide.
The cathode region of the initial curve includes a series of peaks in the range from 0.15 to 1.65 V associated with the reduction of metal oxides (Eq. 3–5) and the formation of Pb and Sn particles, as well as their subsequent alloying with lithium (Eq. 6, 7).
The results are in a good accordance with the data of cyclic voltammetry.

X-ray diffraction (XRD) data were carried out at the room temperature using a Philips PW1830 diffractometer with Cu Kα radiation in the 2θ range from 30° to 60°.
The refinement of the XRD data shows that all the compounds crystallize in the Fe2P-type hexagonal structure (space group) with small amount of impurity phase with space group of Fm3m, the lattice parameter a increases (from 6.0461 to 6.1077) and the lattice parameter c decreases (from 3.4326 to 3.3360) with increasing B contents (from x = 0.01 to 0.04).Analysis of XRD patterns reveals that the compounds contain a small amount of impurity phase which has been identified to be cubic (Mn,Fe)3Si phase, we found that the peak intensity of second phase becomes less with increasing B contents.

In particular, the data reported in Table 1 have been here assumed for deriving the analyzed solutions.
Data accounted for the theoretical model and the FE analyses.
In particular, from the figure it is evident that the load P grows almost linearly with the slip, and the subsequent formation of cracks leads to both drops of the load P and, as shown in Figure 6.b, also to a progressive reduction of the shear stiffness of the strengthening system.

Transition metal ion complexes, especially in the form of stearates, are used as pro-oxidant additives which induce abiotic (photo or thermal) oxidation leading to reduction of molecular mass [2].
Using the data on the maximum weight uptake and loss, mean effects and analysis of variance (ANOVA) were employed to determine if thickness and colorant additive significantly affect the sorption kinetics of PE films immersed in different aqueous solutions.
Conclusion Our data indicated that white colorant additive significantly affects the sorption kinetics of pro-oxidant-loaded PE plastic bags during exposure to different aqueous media at 60 °C.

In this section, the effect of denatured bath of the protein fibers on the colorimetric data of the reactive dyes was evaluated and the results were shown in table 5.
Table 5 Colorimetric data of the dyed soybean fiber with different process C.I. reactive Fabric L* a* b* C* h Red 238 Alkaline bath 39.84 54.50 -0.80 54.50 359.16 Denaturated bath 37.63 56.80 2.87 56.87 2.89 Yellow 206 Alkaline bath 68.59 26.70 66.35 71.52 68.08 Denaturated bath 66.68 28.53 67.90 73.65 67.21 Blue 235 Alkaline bath 36.68 -8.05 -18.72 20.38 246.73 Denaturated bath 27.94 -5.67 -17.26 18.17 251.83 Bursting strength of dyed soybean knitted fabrics.
As the date shown, after the denatured bath, the bursting strength of three dyes were both reduced compare to the fabric’s bursting strength before dye, but the reduction was in 5%, so denatured bath has no great effect on wearability of soybean fabrics.

Introduction Porous metal material due to its advantages of light weight, high stiffness, and high heat-resistant temperature, is widely used as a shock energy absorption, noise reduction, electromagnetic shielding, heat insulation, or corrosion resistant material in engineering.
Schematic diagram of the structure of test system The diameter of impedance tube in Fig.3 is 29mm, in this work, the temperature distribution over cross-section of the acoustic impedance tube is nearly uniform according to measured data.
Experimental Data Analysis 4.1 The Effect of Temperature on the Sound Absorption Properties of Porous Metal Materials Backed by Rigid Wall In order to explore the effect of temperature on the sound absorption performance of porous metal materials, the specimen is placed close to the end cap of impedance tube, i.e., backed by rigid wall.
