reduction of TADP was superior to that of MADP.
bAs CODCr Table 2 shows the reactors' performance data during the steady state condition at HRT 30 days.
If aimed at TWAS reduction, TADP is more suitable than MADP.
The VS reduction in TADP was same as that VSS reduction in MADP.
However, the VS reduction in MADP was lower than VSS reduction in TADP.

Rising the test temperatures above ~ 420 K, was found to result in reduction of the flow stress to the values received for the industrial material (IM).The formation of coarse primary intermetallic compounds, which is typical for IM material, was effectively reduced for RS material.
According to the literature data, the cooling rate during rapid solidification is about 5×105 [K/s].
Significant improvement in reduction of primary intermetallic compound size is evidenced for PM material, however local colonies of particles, varied in size, are observed (Fig. 1b).Typical STEM and TEM microstructures of as - extruded Al-2Fe-2Ni-5Mg IM and Al-2Fe-2Ni-5Mg PM alloys are shown in Fig. 2a, 2b and Fig. 3a, 3b, respectively.
SAD patterns displayed in Fig. 3a and Fig. 3b correspond to monoclinic FeNiAl9 phase, thus is adequate to literature data.
Maximum flow stress value depends on deformation temperature as shown in Fig. 4b Increasing deformation temperature above ~420 K induces reduction of mechanical properties to the level corresponding to properties of conventionally prepared material.

The behaviour of grains is governed
by strict and unique laws and, consequently, each program execution starting from the same initial
data leads to the same final result.
Study of recrystallization in copper Several simulations were performed using stochastic vertex model in order to explain the recrystallization texture formation in rolled polycrystalline copper after high (90% reduction) and low (70 % reduction and below this value).
In the case of 90% reduction, the deformation texture is very similar in terms of main components but is more intense (Fig. 3a).
On the other hand, in the material previously rolled up to 90% reduction, only the cube component is present after recrystallization (Fig. 3b).
The starting maps for both levels of rolling reduction (70% and 90%) were the same as in the calculations in deterministic vertex model [1].

Accuracy of the traditional CGT model was verified by comparing simulation data and test data.
Then characteristics of hybrid CGT were studied by comparing simulation data of the two models.
Therefore , further reduction of CGT’s emission and fuel consumption is crucial[1,2,3].
Up to now, most researchers in automotive field have been put their attention on commercial vehicles, while only few researchers’ study the CGT’s emission reduction and fuel saving.

Experiment results indicate that temperature reduction will widen the optimal operating region and increase the optimal multiplication; therefore APD will be more sensitive.
The major objective of this paper is to report a series of experiments completely characterizing the commercial APDs working in Geiger mode so as to provide useful data for single-photon detection.
The data provided by the manufactory for these APDs is almost measured under room temperature and with continuous weak light level, so is not suitable for applications in extreme situation.
From the point of view of SNR and multiplication, the advantage of temperature reduction can be easily seen too.
Temperature reduction can lower the ground noise and avalanche noise of the detector, so the optimal operating multiplication moves to Mama at 248K in fig. 2(b).

With the ongoing energy saving and emission reduction projects, cold storage constantly faced with the challenge of energy efficiency indicators.
However, there are seldom research on achieving the substantial reductions of comprehensive energy consumption from cold storage’s energy comprehensive utilization and recycling.
If the condensing temperature is 40 ℃, aquatic cold storage’s refrigeration tonnage is 2.5 million ton (China's statistical data of 2005), each year the exergy amount in the waste heat which aquatic cold storage emitted through the condenser is equal to 5.5 × 107kWh of electricity.
The calculation of the drying system’s capacity is based on the cold storage refrigeration system’s condensing sensible heat’s releasing quantity, so as to determine the heat recovery heat exchanger’s structure, type and size, and to determine the dry volume of the materials in the drying chamber, solar collector area can be determined by the amount of dried material; during summer time, it can heat air to 60 ℃ when work independently, this was used for the design conditions, and using the local solar radiation as a reference data calculated the solar heat collector area, then selected the appropriate heater collector and inclined built it on the top of the drying chamber in the direction of the latitude.
The device coupled the two high-energy processing methods, food frozen and drying together to achieve comprehensive energy consumption of one end input, which greatly improved the efficiency of cold storage refrigeration system’s comprehensive energy consumption, and provided research direction for cold storage refrigeration system to achieve energy savings and emission reduction.

A defect reduction mechanism was proposed based on this discovery.
Together with other applications for energy infrastructure and the most recent rising demand for data centers that are reliant on artificial intelligence (AI) technology, SiC systems have been giving benefits in a way of saving very large amounts of energy every day.
TSD maps were generated by XRT Toolbox software, an automatic XRT data processing tool to generate defect analysis reports.
Cropped overall XRT image (E=8.05keV, g=0004) of the axial sample to study the cause of TSD reduction at the facet boundary.
A schematic showing the cause of TSD reduction at the facet boundary.

We have made considerable progress in energy saving and consumption reduction, in particular, some technical indexes have reached the advanced level in the world.
At the same time data acquisition are implemented on energy flow and energy flow network so that we can forecast dynamically, make decisions offline, schedule real-time, operate in the optimization, grasp the dynamic change law of relationship between energy supply and demand, solve the using problems of surplus gas, oxygen and heat power to reduce their dissipation, which makes energy saving and zero emission true.
The production data indicates that the influence ratio of concentrates technology on technical progress of iron-making in BF is about 70%.
Empirical data shows that when hot blast temperature increases by 100℃, coke ratio can decline 15~30kg/t with the allowance of more 30~40kg/t pulverized coal injection which improves the production 3%~4% and leads to significant economic benefits.

The work is devoted to the reduction of defective weld deposition zone of the pusher, as well as the reduction of the number of defects such as low density of metal, pores, shrinkage holes.
Bubbles can be the consequence of the emission of dissolved gases: hydrogen, nitrogen and the formed insoluble metal oxides of carbon produced during the solidification of metal by reduction of its volume, which leads to the formation of internal shrinkage with coarsely crystalline structure of the surface covered by a layer of oxides.
According to the data given in Table 2 and represented in Figure 12, the analysis by the method of passive experiment was performed.
