Reduction of titanium raised with the increasing of TiO2 in slag, , and dissolved in hot metal, simultaneous there is a certain amount of TiC, TiN and Ti (C,N) formation, with the increase in furnace charge bearing titanium[1,2].
Ti reduction in blast furnace is predominantly by the reaction of TiO2 in slag and fixed carbon of coke, then can dissolve in molten iron.
The combined effect of [Si] and [Ti] concentration is slightly smaller than [Ti] content to viscosity with the previous results mentioned that the data by Wen Guangyuan et al[5].
Moreover, furnace temperature over high will increase the reduction of titanium, resulting in the precipitation of titanium, hot metal become viscous, and its flow properties deteriorate, the desulfurization capability of it will be further affected.

There is little literature data shows the change of silicon-carbon composite material and SEI film in the lithiation/ delithiation process.
The CV, without cycle, has excessive reduction/oxidation peaks because of the sum of silicon, carbon and the silicon-carbon composites (through Figure. 1 shows) cyclic voltammogram.
And there is an obviously reduction peak at 0.05 V, is consistent with the characterized potential of Li15Si4.
There is a reduction peak at 0 V which corresponds the generation of a series of LixSi alloy [11].

The data presented in [7] revealed that the stress-strain response is sensitive to the strain rate during the curing process of the composite.
●Subsequently, stresses increased due to polymerization, stiffening and a reduction of visco-elasticity of the composite (150-450s).
Figs.2 and 3 shows that the process can be divided into three different phases: ●a viscous behaviour phase ●a reduction of visco-elasticity behaviour phase ●an elasticity phase Microcracking and interfacial failure may occur due to residual stress, or as a result of resin-based composite polymerization.

Experimental data proves that with 10% engine bleed the flow distortion was reduced up to 42% and ram pressure recovery of up to 0.96 relative to free stream[9].
The heat exchangers have been prominent generating combustion temperatures at low OPR of 30 providing substantial reduction in TSFC values.
The technologies involved for the engine assists in noise reduction by approximately 35-40db relative to present engines, NOx emissions are reduced by 70-80%, the SFC has been improved upon by 50%.

Experimental data in Fig. 5(a) demonstrate that compressive strength decreases dramatically with increasing MBV when water content is increased under constant flow.
Moreover, compressive strength appears to have a negative linear relationship with MBV, which confirms that the reduction is directly related to the increase of water content.
However, this reduction is considerably limited as compared with the reduction in Figure 4(a), revealing compressive strength is remarkably reduced only when W/C is increased due to growing water demand, which contradicts with traditional academic views.

Load cell recorded forming load as a function of displacement in time behaviour and displayed the load data in computer software.
Fig. 3 shows friction measurements are presented for a range of conditions, including changes in lubricant, strip reduction and strip roughness.
Measurement of friction coefficient on the contact sliding surface, particularly at 45° tool die reduction area, in strip drawing is given by Eqn. 3 [7]
Results and Discussion The mechanics of strip drawing began by placing the aluminium strip in the die container at the die opening reduction region.

The reduction in the projected area makes the thickness of the cured layer more prominent.
This substantial reduction highlights the significant role that Sudan I plays in modifying the curing dynamics of the resin.
(a) Exposure time vs. layer thickness for raw resin, resin containing additive CB, and Sudan I, respectively; (b) Zoom in the data of resin containing additive CB and Sudan I.
This reduction brought the layer thickness closer to the usual minimum layer dimension setting of 5 μm, showcasing the effectiveness of grayscale adjustment in achieving finer control over the printing resolution and precision.

Regarding the mechanical properties, the Hall–Petch relationship indicates that the reduction of the average grain diameter leads to the increment of strength.
Polarization curves of samples Electrochemical tests were performed to get accurate electrochemical data of pure Mg.
For as cast pure Mg, the corrosion potential (-1.65 V) is lower than that of as extruded ones (-1.30 V); Meanwhile, the current density (1.00×10-5) of as extruded pure Mg has apparent reduction comparing with that of as cast pure Mg (1.47×10-4).
Furthermore, dilution of segregated impurities at grain boundaries is well-known beneficial effect of grain size reduction for corrosion resistance [9].

Indigo reduction/oxidation process can be described as scheme 1.
Scheme1 Indigo reduction/oxidation process In practice, the indigo dyeing is carried out in warp yarn form; the yarn is running continuously, the yarn is in the form of a full-width warp beam or a string of yarns with thickness similar in size to a thumb (ball warp), containing 300-400 individual threads.
The reduction was carried out for 60 min, and taken 50 ml of above concentrated leuco solution to prepare 500cm3 of diluted solution by the addition of distilled water, the calculated amount of each auxiliary was then added to diluted leuco solution to form the final dyeing solution, the dyeing solution is composed of: (1) Indigo Blue (gdm-3) 5 (2) Sodium dithionite (gdm-3) 12 (3) sodium hydroxide (gdm-3) 8 (4) dyeing auxiliary (gdm-3) 1.0 The cotton fabrics of the size of 20.0cm×25.0cm were impregnated with the dyeing solutions at 25 º C by passing through the mangle nip to squeeze the surplus liquor (80% pick-up), then oxidized for 75s in the air and washed by tap water.
Effects of auxiliaries on the dyeing performance Dyeing performance can be expressed by color yield and grade of rubbing fastness of dyed fabric, all data were measured and recorded in Table 2.
