The influence of Ti/N ratio on the effective boron and mechanical properties was investigated by analyzing data from low carbon boron alloyed bainitic steel plates.
The reduction of each pass was 10~20 %.

The simulated strain relaxations for thin metal sheets are evaluated with an algorithm as used in commercially available evaluation software (i) for uncorrected data as well as (ii) for strain data corrected by the proposed correction procedure.
Furthermore, the surface data are excluded.
The necessary training data can be determined by a sufficient number of specific FE-simulations (9 simulations lead to an error of only 0.14%).
Through the presented direct strain correction in combination with a stress evaluation using commercially available software (and the implemented calibration data for bulky samples) a noticeable reduction of the mean stress deviation is achieved which is in tolerable limits with respect to practical application.
Without application of the correction the herein implemented calibration data/functions lead to erroneous results due to the decrease of the local effective stiffness at the measurement position for which the calibration data in general do not account for.

In 2003, the British government proposed greenhouse gas emission reduction targets in the < Energy White Paper> that in 2050, they will reduce carbon dioxide emissions by 60% at 1990 levels, and establish a low-carbon economy society.
Data This paper selects data sample of years 1990-2011, and the data of energy consumption and GDP is from the China Statistical Yearbook.
We use data’s logarithmic form to eliminate heteroscedasticity.
We make ADF test of the data before establishing VAR model, we find that all variables are integrated of order one at the 5% significance level, so it is reasonable to establish the VAR model.

This paper proposed that install the AE sensor on the base for collect the fault AE signal, but the signal was weak, so carried on EMD first, and selected the former 8 IMF to construct the original feature, than carried on KPCA for dimensionality reduction and get the optimized feature.
Use SWAES’s full waveform acoustic emission detector and acoustic emission data acquisition system for data collection, setting the sampling frequency fs = 1MHz, sampling time t = 0.5s, the speed was 2160 rev / min.

The main advantages of using SMAs include the reduction of the system weight, the ease and reliability in application, and a simple control strategy.
In this way, Tab. 2 lists data relating to input currents (I), activation time of SMA elements (Ton), maximum temperature reached during test (Tmax), cooling time of SMA actuators (Tr), minimum temperature reached during the test (Tmin) and test duration (Ttot).
The temperature behaviour (a) on the SMA element and IR data collection (b).

Preface The dish-shape metal corrugated pipe is widely used in petroleum, electricity, chemicals, metallurgy, marine, aviation and other engineering equipment, as the role of seal, vibration absorption, noise reduction, energy storage, thermal compensation, media isolation, and so on.
The test system of the apparatus includes: Random signal and system analyze is software SSA V7.0, Signal conditioning instrument AT04R, Data acquisition NI9215A, Acceleration sensor CA-YD-115, Hammer 5113 type force sensor, Test bench, A type of dish-shaped metal corrugated pipe, Standard block quality.
Test method: Percussing the dish-shaped metal corrugated pipe with hammer, using Acceleration sensor, Data acquisition, Signal and system analysis software, etc, we can easily access to time-domain and frequency domain signal, measured of dish-shaped metal bellows natural frequency.
Test system is shown in Fig. 5, the experimental datum are shown in Table 1.
Through the datum in Table 1 into the formula above, we can calculate the dish-shaped metal bellows' stiffness coefficient k=33.4, through the regression formula to, correlation coefficient r=0.99.

This interpretes that insertion of a thin Zr layer into Zr-N film is attributed to the densification of grain boundaries in ZrN/Zr/ZrN films followed by the reduction of fast diffusion of Cu through ZrN /Zr/ ZrN multilayered films.
Since XRD data do not indicate any other phase formation and there is no considerable increase in the sheet resistance value after annealing at 700 °C, the formation of these small islands indicates the onset of Cu agglomeration.
The significant improvement of ZrN diffusion barrier property by the insertion of a thin Zr layer into ZrN film was attributed to the densification of grain boundaries in Zr-N/Zr/Zr-N films followed by the reduction of fast diffusion of Cu through Zr-N/Zr/Zr-N films.

Main conclusions are drawn as following: (1) high geothermal or geothermal gradient accelerates the reduction of sandstone porosity, (2) high geothermal or geothermal gradient can improve the reservoir properties by promoting the dissolution of carbonate minerals, the filling of hydrocarbon and the development of overpressure, (3) overpressure can preserve partial primary pores, (4) overpressure can inhibit the growth of some cements and slow down the destruction of diagenesis on deep reservoir, and (5) overpressure can generate some secondary pores by enhancing dissolution.
Specifically, high temperature accelerates the reduction of sandstone porosity but improves the reservoir properties by promoting the dissolution of carbonate minerals, the filling of hydrocarbon and the development of overpressure.
