An examination of EIS shows that the physical nature of the equivalent circuits can be interpreted based on the correlation of the interfacial corrosion reactions and the electronic properties of the passive film.

By its properties, phosphogypsum is close to natural gypsum and can be considered as its potential substitute.
Phosphogypsum exhibits thixotropic properties, that is, it is capable of dissolving under mechanical influences (vibration, mixing, shaking).
Thus, in the initial stage, processes of dehydration and physicochemical sealing prevail, which leads to the formation of a denser sediment, which has cement bonding properties.
During interactions with water, phosphogypsum changes its state and properties, which affects the process of accumulation and migration of compounds, both in the dump itself and in the components of the natural environment.
The water-physical and agrochemical properties of phosphogypsum and soils were studied according to the generally accepted method.

Thus, a whole range of factors associated with the manufacture of raw materials and the steel products themselves (profiles, fencing, panels, etc.) has a significant impact on the occurrence and development of corrosion processes for products from galvanized steel.
We will consider the main features of the process, which subsequently affect the quality of the zinc coating.

According to the building layout, frame columns spacing are around 8.0m, if the common cast-in-situ beam-slab system is adopted, the beam height will be close to 1.0m, in lower space the beam will highlight the roof about 0.8m, the perception of quality is affected , and as the load for the plate in the project is relatively large, the deflection is difficult to meet the design requirements, it can only be used in traditional stiffness floor form such as tic-tac floor or multi-ribbed floor.
Compared with the honeycombed core hollow floor, tic-tac floor and multi-ribbed floor in the construction process not only exist on the characteristics of the heavy side mould workload and a long period, but also by the structure calculation, the frame beam around 1 m, plus set fire sprinkler pipe and other factors of square surface to be considered, the floor clear height has been far from the use requirements.
Experimental study on mechanical property of stiffening- ribbed- hollow- pipe cast-in place reinforced concrete girderless floor[J].

Comprehensive considered factors of test measurement precision, test site, and loaded ability, etc. determines length scales of model λ= 200, other corresponding physical quantity of model scales respectively : weight scales λw=λ3; pressure scales λp=λ; the end wide in test B=0.14m, thickness t=0.14m, 28m; The sample particles was gradation particles material made by pmma, particles had better irregular rate, and hadnot sharp edges and corners, its weight errors was controlled within ± 5%, gradation material top load imposed by 5N, 10N, 15N, 100N, 200N, 300N, rectangular load inprototy respectively.
Fig.3 Different strain load affect comparison It can be seen in Fig.3, there was a linear positive correlation between road material external loads in vertical (vibration compacting) and trends of diffusion and attenuation, as the load increases, transfer depth also increases.
Vibration compaction load is effective to the particles under active state because particles can move and the space structure of the material can be changed as well as the mechanical property of the material can be inhanced only when their acceleration is greater than the one of gravity .so, the activation area can also be called as effective compression area.The canonical active region of vibration compacting load is shown in Fig.6.

Properties of the numerical models used for model validation are presented in Table 1.
Since no symmetry can be used in the model with LAV, the fluid domain mesh was refined toward the ignition point of the charge using the biasing factor of 4, in order to reduce the model size as well as to ensure the validated blast wave loading parameters [7].

Industrial design is the source and one of the core impetus of manufacturing industry’s competitive power, it has a direct affect on manufacturing technology as well as the brand construction, especially the automotive design, which as the senior stage of industrial design.
In recent years, automobile OEMs in Wuhan are beginning to create their own brands, developing proprietary intellectual property rights, but because of the mechanism, host plants haven’t invested enough for design, and don’t spend much on cultivating the designer team, core designs are still bought from abroad.
In general, because of regional, traditional manufacturing constraints and other factors, industrial design sense is not popular yet applied to manufacturing industry in Wuhan, enterprises and the public know little about the industrial design, the industrial design is not optimistic in Wuhan which is the representative city in the central area.
Facing with this problem, Zhao Bo who is the industrial design director of electrical and mechanical institute in Qingdao University believes : there is only a few the official industrial design competitions, mostly are folk organizations, hoping that national authoritative competitions can be held in order to promote the development of industrial design industry.

The components supporting optical networks can be realized by combining clever optical microsystems with micro-electro-mechanical-system (MEMS) actuators.
Mirrors can be introduced to fold the propagation length between the input and output fiber arrays, resulting in a more compact switch form factor.
The 1×K WSS module, which can be used to construct an equivalent K×K WSXC, is more robust solution as the traffic is partitioned according to originating fiber port, and only a subset of the traffic will be affected by a single failure.
The second subassembly introduces the desired wavelength-selectivity property with the use of a diffraction grating.
Switching is performed by a high fill-factor array of tilting mirrors. a separate mirror in the array for independent addressing.

Because of these excellent properties these foams can be used to make bone implants.
In view of the above, a large attention is being paid for making Ni-Ti foams and to characterize them interms of their architecture and mechanical properties[10-21].
The present paper aims at assessing the porosity fraction and micro-architectural characteristics of Ni-Ti foams by using NH4(HCO3) as space holder in varying proportions and finally to characterize these foams in terms of microstructure and mechanical properties.
