Based on existing research data[3,4], the formula of critical edge pressure of foundation has been put forward when K0=1 under this assumption.
Case data is substituted into this paper formula.
The range of reduction of value is 0.009m~0.126m.
The range of reduction of value is 0.339m~1.654m.
The range of reduction of value is 0.583m~1.434m.

For conventional machine tools, the further shortening of auxiliary hours has been very difficult, thus only a significant reduction in cutting working hours (to improve the working feed rate like cutting speed and feed rate.) is possible to further improve the productivity of the machine.
Structure diagram and finite element analysis results Data Analysis Structure Description Option 1 Beam weight 3.19 tones.
Many weight gain, a corresponding reduction in deformation amount.
Switch the whole as square box, not hatchback, simultaneously more weight gain, a corresponding reduction in deformation amount Analysis of testing result.Compare various design options and select the best solution.
We deduced the following formula: (1) Derived from the data in Table 2 and the casting manufacturability, although option 3 and option 4 have a improved maximum deformation compared with option 1 and option 2, option 3 and option 4 have a larger structural weight, but poorer casting manufacturability.

In the literature, a TED reduction has been already observed in similar conditions [14] while no information on B electrical activation is reported.
In Fig.4, we report the carrier concentration versus depth profiles calculated from the SCM raw data taken at the centre of the windows in Fig.3(a) and (b), respectively.
These features are consistent with those observed in the SCM data in Fig.4, which showed a higher electrically active B level in sample (A) than in sample (B) and a similar box-like shape in the implanted B profile.
(iii) The reduction of I supersaturation by the presence of the nanovoids distribution causes also a reduced formation of B-I clusters, which make B electrically inactive.
Conclusion In conclusion, we demonstrated the effect of performing a high dose 20 keV He + implant before the implantation of B at low energy (3 keV) and the subsequent thermal annealing at 800 °C for 12 min both in terms of B electrical activation and of B diffusion reduction.

Currently, there is a reduction in the limits of hazardous substances stationary sources of risk to qualify under the SEVESO III directive force.
The need for algorithm evaluation of unclassified risk sources the determining separation distances are based on data contained in the manual on the method of IAEA-TECDOC, which lists the recommended distance of industrial enterprises from populated areas (Table 4).
In this case, the estimate of bystanders can be determined on the basis of operating data and experience.

The proposed approach can contribute to the prevention of accident of unclassified risk sources because identification and risk assessment is a prerequisite for the reduction and risk management.

The influence of the partial replacement of slag by CKD is unclear from the obtained data.
Maybe some shrinkage reduction can be achieved, but one cannot expect very significant reduction.
During the demolding samples with 5% slag replacement were broken, so only the data for 2.5% replacement are available.
Higher dosage of FBC fly ash can possibly lead to even higher shrinkage reduction, but especially at higher replacement levels negative impact on the mechanical properties might be expected.

The balls weight before and after ball milling were weighed and it was found there is slight reduction in the alumina ball.
The data in Table 1 is plotted in Figure 3 and 6 for further analysis.
The data in table 2 is plotted in Figure 8.

The milling hours had good effect on the reduction of crystallite size and increase in the lattice strain for both alumina and zirconia.

As is well known in the literature, the rate of consumption of these fuels significantly exceeds their reserve formation, leading to a continuous reduction of available reserves [9].
Associated with the growth in demand for electricity is the reduction in energy from available water sources, with a drop of 0.4% in 2020 compared to 2019 [11].
This paper analyzes the data obtained from computational simulations conducted using the EnergyPlus software, to examine the influence that electrochromic devices have on the thermoenergetic performance of a residential building, compared to double and electrochromic glasses.
To perform the simulations, the characteristics of the building, its materials and the climate file are used as boundary conditions, and configured in the input data.
In the simulated cases, data on external monthly average temperatures were also collected, in addition to the operative temperature of the environment, which made it possible to calculate of thermal comfort level.

Environment protection ability mainly includes reduction rate of material consumption x55, reduction rate of energy consumption x55, treatment ration of industrial waste x56, recycling ratio of resource x57, and so on.
This tool establishes double feedforward neural network based on selected data, trains this network by Levenberg-Marquardt backpropagation algorithm (trainlm), finally assesses network effect through MSE and regression analysis.
If the network's performance on the original data is not satisfying, train it again or increase the number of neurons or get a larger training data set until a satisfying network is obtained.
For example, to evaluate green sustainable innovation ability of other enterprises or some sample enterprise in following years, just import input data, and get output result based on fitting neutral network system.
Because of business secrets, the paper hides original data and enterprises’ name.

In order to evaluate whether SCR denitration equipment can attain expected performance guarantee index, and provide technical basis and necessary data for business claim, generating unit acceptance and power plant operation, the performance test experiment should be carried out on flue gas denitration equipment after the generating unit trial run for 168h under full load.
There exists certain risks when using performance experiment as the basis of denitration system acceptance, which is due to the short period of performance experiment, and the requirement of furnace load stability and coal quality stability for guaranteeing the stability of data has no representation to the long-term operation status of generating unit FGD at the later period.

All data listed in Table 2 refer to the mean of each steady stage.
The results were similar to that of the above start-up period (data not shown).
All data listed in Fig. 3 refer to the mean of each steady stage.
As shown in Fig. 3, the total nitrogen elimination rate increased from 0.236 kg N/(m3.d) to 0.826 kg N/(m3.d )with the stepwise reduction of HRT from 2d to 0.5d.
The operation of the ANAMMOX reactor was almost stable in terms of nitrogen removal efficiency during the stepwise reduction of HRT from 2d to 1.0d.
