Table 2 depict the corrosion rate data of Zn electrodeposited PCS without additives.
Table 3 depict the corrosion rate data of Zn electrodeposited PCS in the presence of 5 ml and 10 ml of ON and GY additives while Table 4 depict the corrosion rate data of Zn electrodeposited PCS in the presence of CS additives.
The proportion of ON coating performance data above 10% threshold value is 32% at margin of error of 11.8%.
Data for mean, standard deviation and margin of error for the coating performance data of ON, GY and CS additive with respect to observation time, additive volume and plating time ON Additive             Plating Time (Mins) 15 18 15 18 15 18 Additive Vol.

The noted reductions in sulfide oxidation were thought to be the result of the various iron-phosphate precipitates.
They proposed a combined biotic–abiotic effect on the initial reduction of acid generation.
Due to biological iron oxidation (data not shown), the redox potential values differed significantly between S and B column effluents.
NPR led concurrently to a reduction in the number of acidophilic iron oxidizers.
The colonization of pyrite coupons in the columns was also monitored (data not shown).

By studying composition of the material, we successfully developed a material that offers both high resistivity and high compressibility, reduction of core loss by more than 20% over the conventional material was achieved.
A crucial prerequisite for reducing high-frequency core loss is the reduction of eddy-current loss.
Ingot electrical resistivity was calculated for each composition according to the data shown in Fig. 2.
The data also show that Fe-2Al permits an even higher density than Fe-1Si, which confirms that aluminum is superior to silicon in that it enables high-density compaction in the ingots.
To stop any further reduction in density and compactibility due to alloying, alloy compositions that would offer high electrical resistivity and high deformability were determined.

The theoretical model is validated by experimental data.
The effect of section dimensions on temperature reduction is less for the temperature of STRC surface, and is significant for the temperature of steel tube surface.
It can be found that the influence of steel ratio on temperature reduction both of steel tube and member surface is less.
Effect of sectional core area ratio on temperature field Conclusion Based on the discussions presented in this paper, the following conclusions can be drawn: (1) The theoretical predictions by nonlinear finite element in this paper are in good agreement with the experimental data
(4) The increase in section dimension results in a temperature reduction within the section, whereas the reduction in temperature becomes less significant when C exceeds a certain range.

Based on the idea of ecological sustainability, this paper puts forward a mode for the overall process of managing the construction wastes in Shenzhen, which can be divided into four aspects: reduction at source, optimization of the transportation, comprehensive utilization and efficient disposal.
The data shows the silts in Shenzhen sum up to more than 10 million cubic meters (weighing 16 million tons by an average density of 1.6 tons/m3), taking up about 70 percent in quantity of the city’s annual solid waste.
The put-forward of the comprehensive management mechanism during the overall processing of Shenzhen’s construction a waste of silts from an ecological perspective The processing of the silts from an ecological perspective is not the afterwards treatments, but to put the viewpoint and stress forward, sticking to reduction, reuse, resource.
Reduction at source The sorting and recycling at source means to share the usable waste metal, wood, paper, bricks and rocks by selling or refilling and smoothing the ground, leaving the rest to be entrusted to the company for processing.
The Shenzhen economic zone silts reduction and reuse guidelines have set up the system for charging for the silts, the fee standard should be determined according to the factors such as the local economy and the actual needs for the recycling and the tolerance of the construction units.

The safety factor of landslide is calculated according to shear strength reduction theory in the numerical simulation software.
Concrete methods and the Data depend on the importance of the construction, the consequence of landslide and the believable degree of basic information.
The safety factor of landslide is calculated according to shear strength reduction theory in the numerical simulation software which is using to carry out strength reduction of materials parameters of landslide also when we designed the landslides state.
Strength reduct On formula is as equation (1): (1) In formula: are reduction of soil shear strength index on slope stability analysis .c and were conventional parameters of soil shear strength index.

Take a scaled model of the reticulated shell structure as an example to analyze, the cross section of one member supposed to have a slight damage of stiffness reduction.
Results of the numerical analysis indicate that the difference of wavelet transform coefficients of modal curvature can be used to locate damage roughly, while the wavelet transform coefficients of modal curvature difference can be used to locate damage more precisely with easier and more reliable data processing.
Damage cases is to weaken the rod 35, which the stiffness of the cross-sectional size reduced toΦ41mm×2mm (equivalent to 24% reduction of the section stiffness).
On this base, process and analyze of the data using the wavelet transform, which can make the signal “zoom in” and interference of some the useless information.

A time dependent corrosion model has been developed for failure prediction purposes, based on the historical data of plate thickness reduction.
In addition to TSCF, Wang et al., 2003, also presented corrosion data in a more recent version, this is data collected from 140 single hull tankers with a total number of 110,082 thickness measurements, vessel age range of up to 32 years and this data was collected from the period 1992- 2000 [13].
The last parameter is derived by considering the corrosion wastage data available in each of the hull structures' locations.
The Chi Square method was used to conduct a goodness of fit test in order to gather accurate data in this investigation.
Decision-makers and inspection planners are given the risk rating data in easy forms to assist them in prioritizing inspection activities.
