But in actual operation of project, many factors affect the productions and emissions of odorous substances.
The malodorous gas composition is complex, and its generation and emission were often affected by the actual process conditions.
The Mechanical biological treatment of this plant is composed of mechanical sorting and biological treatment.
The differences between the different components on many physical properties (e. g Density and volume) were used for mechanical sorting to do screening pretreatment of garbage.

The magnetic medium phase directly affect the magnetization of abrasives, The composition of abrasive phase and particle size influence grinding ability of magnetic abrasives, The magnetic medium pahase combined with abrasive phase is solidifies to spheric abrasives of a certain size by binder.
Therefore, the total magnetic force acting on the abrasives F is as follows: F=FX+Fy (3) From the equation (3), it can be seen that the magnetic field strength is the main factor affecting the finishing effects.
Equation (1) and (2) show that the magnetic field strength, abrasive composition, size and ratio would directly affect the magnetic field force, so the magnetic field force and abrasive physical properties (composition, size and ratio) are the main factors affecting the machining effect of rotating magnetic field magnetic abrasive finishing.
Experimental research on the abrasive physical properties is carried out for inner hole surface using the equipment shown by Fig.3.

Hence the results suggest that the sub-Rouse modes and their properties are generally found in amorphous polymers by mechanical spectroscopy, and reveal the cooperative nature of the sub-Rouse modes.
Introduction From the accumulated studies by many researchers for more than half a century, the research field of polymer viscoelastic properties has arrived at a stage of becoming mature.
Another purpose of the study is to examine the effect of MW and structure on the sub-Rouse modes and its properties.
These similar properties indicate that the sub-Rouse modes, like the local segmental relaxation, are intermolecularly coupled and their dynamics are cooperative.

When an aluminum alloy for traditional heat-resistant 2219, 2618, its working temperature exceed 200℃ after coarsening main reduce the mechanical properties significantly.
Figure 5 Polarization curves of intergranular corrosion of specimens Discussion Due to the addition of a small number of metal elements Ag, the Al-Cu-Mg-Ag alloy formed on the basis of Al-Cu-Mg aluminum alloy has a better aging hardening effect, because Ag causes the alloy's surface to have a strong precipitation hardening effect of the Ω phase[13], The Ω phase is a key factor affecting the mechanical properties of the Al-Cu-Mg-Ag alloy, so as the solid-soluble temperature rises from 505 to 515℃, the diffusion rate of the atom increases, and the Ω phase increases after 185℃\4 h aging treatment, resulting in an increase in the Ω phase.

We found that the resulted nanocomposites exhibit high conductivity and strong ferromagnetic properties.
Co-Fe3O4; [Co-Fe3O4]:[EDOT]=1:0.95 (B); 1:1.9 (C); 1:3.8 (D); 1:7.6 (E) Electromagnetic Properties.
It is found that the electrical and magnetic properties of the Co-Fe3O4/PEDOT-PSS nanocomposites are strongly affected by the [Co-Fe3O4]:[EDOT] ratios.
The macroscopic conductivity relies on some external factors such as compactness, defects and density that relates to the physical property of the sample.
Whereas, the microscopic conductivity of the material is associated with the doping level, conjugation length and chain length etc. factors that is determined by the polymerization conditions.

The paper describes the principle of innovative welding method known as Delta Spot and evaluates the properties of Delta Spot joints made by combination of galvanized steel sheets H220PD (a0 = 0.9 mm) and TRIP 40/70+Z100MBO (a0 = 0.77 mm).
The properties of Delta Spot joint were compared to the properties of standard resistance spot welds.
Chemical composition and mechanical properties are listed in Table 1 and 2.

The temperature gradient and plastic thermal deformations determine microstructural changes, diffusion phenomena and mechanical properties of the finished product.
Unfavourable thermal and stress effects are intensified when materials of different heat and mechanical properties, like Al2O3 and Al, are bonded.
This phenomenon occurs due to the different thermal properties.
The discrepancy of the two temperature profiles is due to some factors.
Among the factors which need to be overcome are poor machine performance, limitations in collecting data and human factors, since the operation is manual.

Physical properties: crystal structure; refractive index; color; density; hardness; particle shape and size (dispersion); specific surface; bulk density; solubility; Chemical properties: pH of water extract; resistance to water and chemical reagents (acids, alkalis); reactivity; acid-base properties of the surface.
The shrinkage of the polymer, in addition to factors such as temperature, cooling rate, pigment concentration, is determined mainly by the degree of crystallinity.
Tests of physical and mechanical properties were performed according to the method [16].

Perhaps, numerical analysis performed by FEM could give the answers referent of all these issues concerning the CCM, because applying a numerical evaluation will not introduce external factors that can affect the recalled strain data needed to perform it.
The mechanical properties established as input data are: E = 210 GPa, σy = 420 MPa and υ = 0.29.
It is considered that, FEM could be the best option for the evaluation of the CCM, because there are not external factors that can affect the recalled strain data needed to perform it.

The compatibility between matrix and filler is an important factor to decide the mechanical properties of composites.
Results and Discussions Compressive Properties.
This shows that PS content is low, a larger mechanical strength of composite resulted from a chemical cross-linking that phenol and formaldehyde were copolymerized with lignin from the peanut shells in H2SO4 catalyst to produce biocomposites as mentioned above.
This shows that adhesion between PF and PS is an important parameter affecting the mechanical properties of composites.
