Data on thermal conduction questions of compounds on a base of poly- chlorines are included in the literature.
In consequence, a reduction in the thermal diffusivity occurs, which can be seen in Figure 2.
In the case of the 8YSZ powder, a main change is related to replacement of a tetragonal phase with a cubic phase with simultaneous reduction of the amount of monoclinic phase.

A reduction in open porosity and pore size leads to a reduction in slag penetration [4][4][4].
Models for calculating surface tension of oxide systems and experimental data can be found in the literature [5,6,7], although they can hardly be applied to complex systems like refractories and melted ashes.

The Inner Lake was divided into 2642 quadrilateral grids with 2880 nodes by gambit software based on the terrain data.
The reduction mostly concentrated in flood season, while it is little in dry season.
Pb pollution load was higher in flood season than that in dry season. (3) The pollution load in three typical years decreased by 65.12%, 54.53% and 62.89% post water regulation compared with that in natural condition, and the reduction mostly concentrated in flood season.

During the sleeping period of "0:00 - 6:00" and "11:00 ~ 15:00" at noon , correction value has a certain degree of reduction based on the set value in the original setting while in the time living of "18:00 ~ 21:00 ",the correction value is increased to a certain degree.
Three-state control principle shows in Fig. 4 when the secondary network for average temperature measured is greater than the upper limit of Pang-Pang, the primary network valve stays in the lower limit operation, thereby decreasing the average temperature, when the secondary network for the average temperature is less than upper limit of | Pv-Sv | ≤ 0.5, at this time if the valve position is still running in lower limit, the average temperature will continue deviates from the set value area, then the valve position switches to valve average position to ease the reduction of secondary network for average temperature; when the secondary network for average temperature measured is lower than the lower limit of Pang-Pang the valve is located in the upper run to increase the heat supply; when the average temperature is more than the lower limit of | Pv-Sv | ≤ 0.5 ,the valve switches to middle position to alleviate the average temperature to continue to rise.
Some evaluation indexes can be obtained from the historical data: Pang-Pang control algorithm, the average overshoot σ% = 7.9%, while the use of three-state control Pang-Pang average overshoot σ%= 3.1%.

This reduction occurs when interaction strengths between its components are above a threshold value [6] fixed by equality between internal interaction power and characteristic cascading power from outer source.
Structure of Filtering Block of Fig.2 with Task Oriented Control The complete scheme developed here can be summarized on the following correspondence table Table I : Correspondence between Various Levels of System Structure, and Dynamical and Information Action Levels Defined in the Model Element System Control Information Level x(t) Point Asymptotic Stability Data Block 1 x(.)
Only manifolds corresponding to system invariants can be separated, indicating a reduction of number of outer control inputs, the other ones being taken care of by system own dynamics.

The ingot was hot forged at 1000°C to 40% thickness reduction and thereafter hot rolled at 900°C to 75% thickness reduction followed by air-cooling.
Our data suggest that in the present b-Ti-15Mo alloy, the twin systems with the highest Schmid factor are also those systems that are most strongly stressed at the grain level.

Specimen size and load and displacement data which were obtained from compressive tests were used to calculate stress and strain.
The fillers could be treated as air bubble defects and would result in the reduction of the composite strength.
The material density would significantly reduce with the increase of HPSM content, but excessive adding of HPSM would cause a considerable reduction in the compressive strength of syntactic foams.

To overcome this issue, inverse calculations were performed to evaluate a reduction constant r to account for material’s softening at high temperatures and extremely high strain rates.
Thus an average of 150K to 200K temperature reduction in tool body has been achieved using coolant flow inside the tool.

Due to the use of mixtures with low amount of mixing water this technology provided for:
• Reduction of pre-autoclave aging of freshly formed raw material to 1-2 hours,
• Reduction of humidity,
• Improved strength, frost resistance and durability of the products with the same density of cellular concrete,
• Increased manufacture of finished products from the volume unit of the autoclave and the production area of the shop,
In order to make products from cellular concrete binding, siliceous components and gas-forming agents are used:
binders:
• Portland cement,
• Quick calcium lime,
• Granulated blast-furnace slag,
• Ash from the burning of oil shale and some types of brown coal;
siliceous components:
• Quartz sand or silica containing waste from mining and processing industry,
• Ash from burning brown and hard coal,
gas-forming agents:

These changes are expected for MFCs, since many researchers [12,13] have found that removal of surface contaminations and reduction of the oxygen group content on anode surface could facilitate the biofilm formation and electron transfer, thus improving the power production of MFCs.
When the MFCs were operated, cell voltage was recorded every 20 min using a data acquisition device (2700, Keithley Instruments, Inc., USA).
