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 functional properties of electrodeposited Ni-Co alloy depend greatly on their composition, which should be strongly affected by deposition parameters such as chemical composition of electroplating bath, electrolyte pH, current density and temperature.
In this paper behaviours of mechanical and tribological properties of Ni-Co coatings with different wt. % cobalt on the current density of electrodeposited process which ranged 1 to 6 A/dm2 were documented and discussed.
According to the authors [4,6] a current density is one of the major factors which influence structure and morphology of the deposited coating.
Tribological properties rated pin-on-disc test using corundum balls with defined test conditions showed good wear resistant properties of Ni-Co coating; the thickness approx 30 mm coating to avoid sanding straight to the copper substrate.

The presence of atomic oxygen at internal metal-ceramic oxide interfaces significantly affects the physical properties of the interfaces which in turn affects the bulk properties of the material.
The presence of solute atoms at internal metal-oxide interfaces influences the physical properties of the interfaces and this, in turn, may affect the bulk properties [6].
The segregation of the oxygen atoms at the metal/oxide interfaces is modelled as a boundary flux q = −w12 · ψ1O + w21 · ψ2O , (2) where w12 and w21 are local transition rates which relate to the equilibrium segregation factor s = w12/w21.
The next step must be to simulate how this segregation influences for example the macroscopic mechanical properties.

The formation mechanisms and properties of white layers produced in precision hard part machining of GCr15 hardened steels are not clearly understood to date.
Klocke et al. presented evidence that in addition to machining conditions, material properties affect white layer generation[4].

Bosheh considered another three important factors are pressure, strain rate and cooling rate[7].
For the machined surface encounters an extremely short cycle thermo-mechanical process.

The key factor affecting the temperature distribution and uniform deformation of the workpiece is die chilling during the extrusion process.
In fact, can and insulating materials contribute greatly to temperature uniformities, and they are also key factors affecting flow uniformity of the workpiece during extrusion process.

Power performance is good or bad directly affects the effect of automobile driving on the highway.
In theory the automobile maximum climbing angle is greater than the actual value because that in actual case as uphill the car will be subjected to the impact of factors such as the wind resistance, the soft or rough surface resistance.

The submarine cable is affected by a variety of factors in the sectors of manufacturing, transportation and installation.
The ultra-high voltage oil-filled submarine cable used in this project is affected by a variety of factors in the sectors of manufacturing, transportation and installation.
Main insulation withstand voltage test is the main method to assess cable insulation properties and the ability to withstand over-voltage.
DC voltage test is easier to detect mechanical damage insulation, bubbles, moisture and other defects; (4) AC voltage test need several cycles to reaching the voltage level needed in the test, while the time of DC voltage test is significantly shortened.
Therefore, the difference of high-voltage lead is one of the major factor leading to the differences of each phase.

According to eigenvalue buckling analysis, the research proves its stability bearing capacity and mechanics properties.
Therefore, in order to promote the development of a new frame formwork support and have a full understanding of mechanical properties, which is necessary for the systematic and scientific theoretical analysis.

If the acting load {P} as working load, the minimal eigenvalue λcr is called structural stability safety factor, related to load.
The frame bearing capacity is mainly affected by the pole, and the maximum stress value appears at the bottom of the pole, as the basic unit.

During carbonization process, the thermal stress concentrates on the relatively weaker fiber / matrix interface, which result in decline in mechanical and thermophysical properties [4].
On the other hand, it will cause decrease in the viscosity coefficient of the mesophase pitch, and foam in some extent, both of above factors affect the crack generating in the carbonization process.
Compare with C140, C170 has lower fracture energy because excessive pre-oxidation temperature affect the MP rheology, MP viscosity, and stickiness properties finally resulting in lower fracture energy.
