Analytic structure model in the analysis process has a high application value, so each risk factor relationships are well to be known.
3 Conclusions and recommendations
(1) Through adequate market research and analysis, to accurate market positioning, market demand and supply risk reduction
Developers when conducting market positioning departure from the laws of the market, on reasonable market segmentation, accurately identifies the type of items to meet market demand, positioning should fully consider the following three aspects: First, the market demand.
Developers respond to the project area through market research to determine the potential market demand and in which the proportion of effective demand, determine the age of the consumer groups and consumer ability occupational characteristics and other data.

Based on the above studies, this work performed SEM-EDS analysis to study elementary variation of fly ash to provide data for stabilization of heavy metals and reuse in construction materials.
Fig.2 Content variation of Ca, Cl and O as a function of temperature S disappears in fly ash sintered over 1000℃ and content of K and Na reduces considerably at 1100℃, which are conducive to reducing leaching toxicity of heavy metals due to reduction of soluble salts (Fig. 3).

Semi-finished products obtained after 5 rotations of the rolls, with the effective strain distribution marked
Based on the analysis of the effective strain distributions both on the surface (Fig. 2) and in the axial section of the semi-finished balls (Fig. 3), it can be observed that the material flows most intensively in the area where the necking is formed and the billet diameter reduction takes place.
The data presented in this figure demonstrate that the function takes – in both cases – the highest values near the neckings where the balls are connected.

Calcination method without additives at high temperature merely remove 15% of S in petroleum coke since organic sulfur can not be oxidized in reduction atmosphere formed by carbon in petroleum coke which accounts for about 88.3%.
The experiment was carried out systematically in order to reduce relative alkali amount, the data of the paper present convenience for relevant researchers. 2.

The viscoelastic materials properties were determined according to the Generalized Maxwell model after calibration of the test data using the 2S2P1D model.
At low frequencies, the observed differences between the numerical and the experimental data were minor.
Figs. 12 and 13 show an agreement between the model and experimental data.
Stiffness master-curves at 15 °C obtained from the complex modulus data, 2S2P1D, and Maxwell models of (a) BBREF_5,3 and (b) BBRAP_3,7.

The paper originally investigates the influence of the admitted ranges of slow-acting filling time of brake cylinder on longitudinal dynamics of freight trains, using experimental air pressure data obtained in tests on filling characteristics.
As regard the filling characteristics of air brake distributors, we considered appropriate to base on experimentally determined data, adequately implemented into the simulation program.
Simulation Assumptions and Data According to the main target of the study, a major objective was to identify and eliminate, as much as possible, any aspect potentially disturbing the direct influence of filling characteristics.
In this respect, the main initial data for simulations were: vehicle’s mass 80 t; length of a vehicle 20 m; the maximum clamping force on one block brake 30 kN; initial train speed 80 km/h; time rate of successive actuation of individual vehicles braking system in long of the train is 0.08 s.
After the first 15 s (see detail in Fig. 5 and Fig. 4, c), a stabilization and even a slight reduction of the differences in braking forces relative to the first vehicle, diminishes, in time, the compression of the train.
