Different evaluation methods were used for the interpretation of the scattering data.
Scattering data were evaluated by Freltoft, modified Freltoft, and Emmerling approximations.
Scattering data were evaluated by Freltoft, modified Freltoft, and Emmerling approximations.
The reduction of BET specific surface area required to get more precise data is ≥ 1015% in the case of fractal aluminosilicate aerogel.
The evaluation of the scattering data depends strongly on the aerogel structures.

Movement between different networks at different intervals using the difference between bandwidth and packet loss handovers of technology are unsafe and will cause a delay of data transmission.
Further reduction can be achieved, though continued research should be considered.
Future research includes reduction of the time-consuming DAD-hours (1000ms).

The temperature data near to fusion boundary, HAZ and base material were measured using thermocouples during welding.
This leads to reduction in temperature gradient (G/R) and promotes equi-axed dendrites.
A reduction in micro-segregation of Nb in the inter-dendritic region is in the order of 25-32% while using the CCP welds with helium shielding gas.

Therefore, the reduction of the induced EMF fundamental component is mainly due to the reduction of the magnetic field.
Conclusion The fault diagnosis of fault-tolerant motor armature windings inter turn short-circuit is difficult, one reason is that the exterior characteristic of inter turn short-circuit fault is subtle, the other one is the lack of accurate characteristic data.

However, a reduction in the grade of the concentrate will inevitably make the unit cost of metallurgical process increase.
M1is the yield of WO3 in the original technology, 2902.2 tWO3/a.P1is the unit price of mineral metal when the WO3 grade of concentrate is 65%, RMB/t M. fd21 is the annual process costs reduction by using the new technology instead of the original one, RMB/a, according to statistical, the actual costs by the original technology is 403.8×104 RMB/a.
By use of data in table 1 and table 2, the relationship graph of E-P0 is calculated according to formula (3), shown in Fig. 3.

They were subjected to laboratory rolling at 1100 °C (25% thickness reduction) and 950 °C (47% thickness reduction) after reheating to 1250 °C for 120 s.
The evolution of the RA in the NbMoAl-2 steel was determined from XRD data collected during in-situ tensile testing (Fig. 3a), whereas the microstructures of the other three steels were examined at 0.05 and 0.12 true strain, as well as near the fracture surface.

Under the Kyoto Protocol the developing countries start to do the obligations of emissions reduction from 2012.
China, the largest developing country, has to face the growing pressure on energy conservation and emission reduction.
(1) The research on the comprehensive evaluation method The principles for grade indicators usually have such things below: The quantitative description of indicators: According to various regulations, norms, standards and other requirements based on the data, or based on common use industry standard, rate according to the targets difficult, slope and linear and has assumed the scoring changes.

From the present work, it is concluded that lignin's rigid network strengthens and minimizes the loss of tensile properties in UcS through the reduction of its biodegradability which occurred naturally by soil microorganisms.
The data were submitted to pair-sample t-test.
These findings confirmed that lignin had strengthened the UcS and reduced its losses of tensile properties possibly due to reduction in biodegradability of starch polymeric network within the composites under aerobic soil microcosm.

Pinnel and Bennett [3] found that by a large reduction in rolling, the alloy didn’t always show brittleness, instead, it had a certain plasticity and toughness.
Through data analysis, their interplanar spacing were both two times of peaks in 44°and 65°directions, which may be DO3 phase, occurred by ordered phase transformation due to the slower rate when cool from 800℃.
Recovery, recrystallization and grain growth will take place during isothermal heat treatment after a large reduction of cold rolling.

The basic input data: gas СО2, gas flow rate 20 l/min, geometry of the welding torch for machine welding with traditional (one-jet) and two-jet gas shielding, front surface of gas flow – plane, distance from the nozzle edge to the plane (welded item) – 12 mm.
It leads to the increase of heat input into the item and into the droplet of electrode metal, heat efficiency upgrading, reduction (under the given conditions) of the heat-affected zone (HAZ) in comparison to traditional (one-jet) shielding.
Reduction of HAZ reduces the risk of weld joints weakening and improves their working properties [8, 11, 12].
