This compound exerted an efficient inhibitive action both on anodic dissolution of metal and on the cathodic oxygen reduction reaction.
This would result in a reduction of the current densities without change of the anodic slope.
The analysis of the results obtained shows that the increase of the inhibitor concentration is accompanied by a reduction of the Icorr, and consequently an increase of inhibition efficiency follows.
The reduction of anodic mainly and cathodic currents in the presence of compound inhibitor can be explained by the blocking of active sites with the formation of a protective film on the electrode surface.
The impedance data were analyzed using the equivalent circuit (EC) model, where Rp represents charge transfer resistance and Cd the constant phaseelement.

Comparing to others, program 1 can not only improve voltage in maximum extend but also can make a 25% reduction of line losses.
Calculation of transformer loss reduction when DG is used to peak.
According to transformer B’s parameters, power losses reduction after adding DG for peaking could be obtained.
The data can be seen in Figure 5, adding DG for peaking can make transformer losses decreased by 23% -25%.

Exterior Wallboards with Exterior Wall Tiles 1.1.2 Reduction in Costs and Convenient Construction Steel consumption of prefabricated buildings is only 30-40kg/m2, saving 30% -40 % of construction steel.
Prefabricated components are on-site assembled after processed in the factory, reducing the turnover materials and tools as well as their leasing expense, the construction speed of part of the buildings has increased by 4-6 times, the economic benefits gained due to the shortening of construction period is considerable. 1.2.3 High Degree of Mechanization and Reduction in Equipments of on-site Construction Staff Prefabricated buildings use a lot of finished and semi-finished components for installation and construction, the labor intensity is greatly reduced, the number of on-site construction staff has fallen more than 30%, which also leads to a corresponding decrease in the number of on-site construction management staff, thereby reducing labor costs. 1.2.4 Features of Thermal Insulation and Superior Performance Prefabricated buildings can organize walls with different thicknesses and structures according to climate and temperature in different regions.
Data show that when the prefabrication rate of residence reaches to 37%, it can save water by 36%, electricity by 31%, reducing construction waste by 83%, simultaneously, achieving 60% reduction in material consumption and 50% in energy consumption. 1.2.5 Environmental Protection and Good Economy Prefabricated buildings are prefabricated and semi-prefabricated, which greatly reduces the on-site wet construction, the great reduction in construction of mould boards and cast-in-site concrete helps to reduce the impact of construction on the surrounding environment, dust and noise pollutions have been effectively controlled.

.), a harmonic drive (SHD-17-100-2SH, Harmonic Drive Systems Inc.) and a reduction system.
This system has advantages compared with a reduction unit using plain gears in terms of high output torque and high accuracy [1].
The input/output ratio from the original motor torque to the output axis of the reduction system is 1/100, i.e. the original speed of the motor decreases through the harmonic drive gear.
The crank shaft in the reduction system oscillated through the motor's output axis.
These graphs included three-dimensional data of the surface, and their roughness values Ra were calculated basing on the JIS B 0601:2001.

Dust Reduction Measures Before the proposal of dust reduction measures it is necessary to assess, whether the dust generation is not due merely to the lack of technological discipline.
In the framework of construction preparation the entity preparing the design of blasting operations must be provided with sufficient data, comprising primarily the size (dimensions) of demolished buildings, description of building materials, technical state of buildings intended for demolition, their connection to utilities and circumstances connected with environs.
Perfect knowledge on these input data co-determines the methods used as well as their success.
However, the ensuing reduction of dust generation is not substantial; · covering of buildings/structures requiring protection.
Although this method brings about good results (some sources claim a 50 % reduction of dust generation), it has its disadvantages, too.

Mostly these influencing parameters result in a further reduction of the compressive strength compared to the strength loss already induced by the temperature.
It is noted that those values are smaller than the strengths found for test samples xxx°C,A,0d, which are from the available test data the ones with the most representative test condition for hot strength.
When for theses conditions the superposition is applied based on the values from Table 4, the derived strength losses are too large compared to the experimental data.
· The studied high performance concrete mix suffers from almost no strength loss when exposed to 350°C and about 35% additional reduction in case of water cooling.
When heating to 550°C, respectively 40% and 30% of reductions are found

This data is usually related to the oven temperature.

They are therefore really complex and need a lot of physical data.
Recently, for very small reductions (temper rolling), Krimpelstätter [13] suggested the importance of a hitherto neglected term in the roll elastic deformation, namely the tangential displacement.
This isothermal model should be precise and robust for a wide range of reduction, strip thickness, rolling speeds, lubricant viscosity etc.
They measured friction in the cold rolling process of aluminium strip at different reductions and oil temperatures.
The authors showed that µ depends firstly on film thickness / combined roughness ratio (H), and on strip thickness reduction.
