Introduction
Incineration is witness a rapid increase for treatment of Municipal Solid Waste (MSW) due to weight reduction and energy reuse [1].
Such a pre-treatment is necessary for reduction of leaching toxicity of the hazardous fly ash.
In addition, they also elaborated the leaching data for selected heavy metals (Cr, Cu, Pb and Zn) obtained from sequential monolith leach tests with a pseudo-diffusional leaching model in order to identify the release mechanisms of such heavy metals and to predict the long-term leaching behavior of cement mortars.

Adopting Japanese evaluation train derailment safety C limit value (that is, derailment coefficient=1.2, wheel load reduction ratio=0.67, lateral wheel-rail force=78kN) as the standards to evaluate the train running safety on rail-bridge during earthquakes.
When the earthquake intensity increased from 0.05g to 0.2g, the vehicle speed limit decrease from 265 km/h down to 23 km/h, a decline of 91.3%; (3) Derailment coefficient, wheel load reduction ratio and the lateral wheel-rail forces are all likely to become the vehicle derailment critical state control parameters, which also reflects the randomness of vehicle derailment.
Fig.3 Comparison between interpolation curves and simulation ones From Figure 3, one can see that the interpolation data curves are consistent with the simulation data curves.
This indicates that the Lagrange interpolation data meet the accuracy requirements of numerical interpolation.
Fig.4 Comparison of interpolation data and specification values From Figure 4, it can be seen that the ground motions have greater influence on trains passing by the simply supported rail-bridge during earthquakes.

., S1 with mgb = 1 and mtj = 1/64) analogously a reduction in the number of grains together with an increase in the grain size can be observed as shown in Figure 2a.
Plotting the mean edge length of each grain versus its relative size, we observe a wide scattering of the data (Fig. 3b).
The data of vs. x for all grains with a certain number of faces s show a strict linear relationship.
The data of all grains with the same s are plotted in Fig. 3b with the same symbols labelled by s.
A reduction of the mobility of triple lines and quadruple points leads again to a reduction of the velocity of growth, where with decreasing mobility the simulated curves become linear over a long range of time.

Previously, studies were conducted in which was justified the choice of the chemical composition of the experimental alloy [20-25], computer models were developed, the modes of hot rolling of model ingots on a laboratory mill of DUO 330 are calculated and tested, and also received data on mechanical characteristics and structure of metal.
After that, temperature, speed and time modes of rolling were introduced, according to the parameters of the industrial process, and with the help of the DEFORM-3D software complex, an array of data was obtained on rolling passes, which included: - the dimensions of rolled products depending on the single reduction; - the temperature of the metal; - forces and moments of rolling.
The authors of this paper showed that when hot-rolled of ingots, the values of the Cockcroft-Latam criterion are the fastest approaching the maximum value at the edge of the rolling stock with a total reduction of more than 70%, which indicates the possibility of forming and further development of microcracks in this section of the slab.
Analysis of data on the metal forming, temperature and velocity parameters of rolling, as well as stress-strain state of the metal obtained in the simulation is described in detail in [20].
The data of experimental studies of the structure and properties of cast, deformed and annealed semi-finished products from the experimental aluminum alloy P-1580 make it possible to recommend the developed technology for industrial development, since the level of mechanical properties of these semi-finished products with a minimum content in the scandium alloy is comparatively high and comparable to high-alloy aluminum alloys such as 01570.
