The specimens were upset to a height reduction of 60%, since almost complete DRX could occur under this deformation degree.
Determination of critical stress and strain using work hardening rate.From the true stress–strain data,values of the strain hardening rate (θ = dσ/dɛ) were calculated for each condition.
Apparently, the fitted curves fairly agreed with the experimental data.Therefore, these curves could be used to determine the critical stresses for different deformation conditions.

How much contribution does the energy-saving emission reduction make?
Construction of renewable energy is focused on monitoring the application of the system by monitoring the breakdown of the content (Figure 3), the data laid the foundation for the development of science and technology for future eco-city building energy efficiency policies to achieve energy quantitative targets.
Each application projects simultaneously measuring device related indicators have been established, if not by the provisions of the real-time data acquisition system for data collection, not acceptance, in order to ensure fair and objective inspection system established.

Experimental system analysis and calculation The main work of three-phase flwo laboratory experiments is to study the slurry transportation and other aspects of drag reduction.According to the study ,it need to establish a small diameter experimental system,the diameter of the pipe is 50mm,the experiment system includes the following sections:main transportation pipelines, cutting and suction device, air entrainment device, capacitance testing device, frequence control module and data acquisition module
(5) Frequency control and data acquisition system: The IPC communicate with the frequency transformer.if the IPC gives out a order,then the drive can rotate at the setting velocity.By changing the parameter of the system it can work in Various working conditions.
Using cross-correlation method to calculate the flow velocity and flow rate of the slurry in the same situation at the different time(including five different time).Comparing the results of related calculations and the actual measurement the data are as tab.1 below: In the tab.1,it give out the result of the flow velocity and flow rate in the same condition at different time.Comparing the flow rate between the cross-correlate method and actual measurement it shows that the maximum error is 18% and the minimum error is 2.3%.The error analysis prove that the cross-relation method is feasible and reliable,the tesing result have high accuracy.

Through this way, they realized the exposure and the reduction of the key of AES crypto chip and gave a new thought, implanting hardware Trojans into the logic chip, successfully.
Among them, and parameters for safe operation waveforms read latency on the data,the parameters can be selected according to the actual operating speed of the chip,selected based on their experience in the general statistical regularities obtained.is the commonly used method for selecting.
Issues related to the work of waveform parameters detailed set of attribute recognition is not the focus of this paper, as in the skip. 2.Waveforms attribute recognition model 2.1 waveforms attribute false identification process handling Definitions 1 "lag" relations: in a group of waveforms, the data on multiple waveform data preparation due time there has led to the theory that signal transitions occur simultaneously, the actual exhibit has hopping phenomenon.

Examining the data of table 3 it is evident that the impact energy increases with the density at both sintering temperatures.
Decarburization is very common in Cr steels sintered at high temperature since the high temperature activates the reduction of Cr oxide by carbon [6].
This is confirmed by the present data.
Samples of B sintered at 1350°C fits very well with the previous data while the same sintered at 1260°C show better impact energy than expected, probably because of the presence of a higher amount of bainite respect to pearlite, as confirmed by both metallographic analysis and microhardness.

The measurement system includes LGY-6 multi-channel wave height gauge, IDTS-4516U series sixteen channel data acquisition instrument, pressure-measuring system and wave run-up measuring system.
Data Processing System.
Data processing adopts engineering general scientific computing and processing software MATLAB.
(2) This structure has an obvious inhibitory effect on wave run-up, and the wave run-up reduction effect of which is much better than cement mortar

In 1992, Donoho and Johnstone proposed the Wavelet Threshold Denoising Method and also gave the threshold value formula, which was applied to a variety of noise reductions and achieved great success.
The method is as follows: It is assumed that if the autocorrelation sequence of discrete data sequence is.

Introduction Since the reform and opening-up, the traditional extensive energy consumption pattern has brought increasing pressure to environmental protection and economic development, and energy saving and emission reduction has been elevated to an unprecedented strategic height.
Output Set for Strong and Weak Disposability Data.
Due the incomplete data of Tibet Autonomous Region and Hainan province, Tibet and Hainan are excluded temporarily, so there are a total of 29 provinces (autonomous regions and municipalities); All data is sourced from the China Industrial Economy Statistical Yearbook, the China Statistical Yearbook, the China Energy Statistical Yearbook, and the China Environment Statistical Yearbook.

Toxicity data for the 50% growth inhibitory concentration against Paramecium caudatum for 26 substituted nitrobenzenes (logIGC50-1) were obtained experimentally.
Molecular descriptor data are often parameters that quantitate physico-chemical properties of the compound. logP is the n-octanol/water partition coefficient, which is hydrophobicity parameter. 1XⅤ is calculated in accordance with its definition.
The ELUMO is used because it appears in direct proportion to its electron affinity and there is an obvious relationship between ELUMO and oxidation-reduction potential.
These data show that most calculated values are close to actual values.

There has been a rapid loss and fragmentation of this habitat over the last half century, which may jeopardize the long-term survival of the species through reduction of dispersal success [14-15].
