This practice does not meet the requirement of energy conservation, emission reduction, low carbon and environmental protection.
This paper chose Parasolid(.x_t) interface for data transfer between Adams and parametric entity models.
The reduction of the amplitude at the rear end of the vibrating screen makes for kernel separation.

To solve the above problem, we use that Matlab has a powerful data analysis, to achieve ultrasonic echo signal denoising.
From the above analysis, the single use of hard thresholding or soft hresholding, noise reduction effect is not ideal.
As can be seen from Table1, noise reduction of the proposed method in this paper is better than other methods both in SNR and MSE sense, and with in a certain range by selecting the appropriate a, b value, the effect will be more obviously.

It resulted in a significant reduction in percentage of water soluble, extractable, carbonate and Fe-Mn oxide fraction of Cu and Zn, and an increase in organic and residual fraction of Cu and Zn in compost.
The reduction in volume of pile after composting also resulted in increased concentrations of these elements.

Before 800°C, the Y4O(OH)9(NO3) and
AlO(OH) phase thermolysised to amorphous Y2O3 and Al2O3 respectively, with aggregation of ash
and reduction of space between powder.
However, while the temperature above 800°C, the YAl4O9, YAlO3, Y3Al5O9 phase was formed sequentially and the reduction of surface area was not so severely.
As reported before, YAG powders have been synthesized by a mixed solvo-thermal method, and IR data also showed evidences of the presence of ethanol group [14].

According to data released in April 2014 from the Environmental Ministry in China, 16.1% of the country’s soil was polluted in which 19.4% from contaminated farmland.
Reduction in crop output due to heavy metal contamination in soil amounted to 10 million tonnes [4].
Solanum nigrum L., Brassica juncea and Pteris vittata L. all showed great tolerance towards Cu and Pb and accumulation was mainly in root zone causing reduction in heavy metal mobility.

If we could utilize the aluminium alloys with higher strength like 7000 series alloys, it has the benefit of the reduction of the weight of the hydrogen tank liner materials.

The data obtained during the production tests on additional flotation of coal foam enrichment tailings using column cells indicate the high efficiency of the process.
At an annual production of primary aluminum at BrAZ of about 900,000 tons per year and an average output of 60 kg of coal foam per 1 ton of aluminum, a 4.5% decrease in fluorine content in the tailings from the fluoride production shop will lead to a reduction in fluorine emissions into the environment by 600 tons, which is 50% lower compared to the existing values.

Latest efforts are focused on synthese of the nanosized MoO2 by different manners as solid reduction [15], electrospinning [16], liquid reduction [17], and rheological phase reaction [18].
As a result of approximation of the experimental data in the case of CPE2 model the following parameters could be obtained: Rct1, T1, f1, Rct2, T2, f2 and Rs (Tabs. 2 and 3).

According to the reference data manganese at room
temperature must have a complex body-centered cubic lattice (α-Mn), and cobalt - a hexagonal
close-packed lattice (α-Co).
The developed technologies in comparison to the conventional ones are more cost and energy saving (due to the reduction of the tin coat thickness from 1.2-1.5 µm to 0.1-0.3 µm and due to the reduction of the chromium coat thickness from 0.05-0.07 µm to 0.01-0.03 µm) and more environmentally friendly (due to the usage of less toxic electrolytes).
