The height of P1 and P2 peaks is decreased with increasing aging time, which is due to the reduction in the disorder degree of the air-cooled specimen.
The whole measurement is controlled by an IBM* 586 computer and an 8087 processor, and the data can be processed in real time.
Therefore, the decrease in the disorder degree will result in the reduction of P1 and P2 peaks in their height.
They will be annihilated when the air-cooled specimens are aged at 350oC or their internal friction is measured during heating, resulting in the reduction of vacancy concentration.

The reduction of resources input and wastes could helps
recycle agricultural resources and produce cleanly in agriculture production, putting the economic
system into material circular process of ecosystems.
However, Projection Pursuit model, an exploratory data analysis method driven directly from the sample data, can overcome those shortcomings.
Examples of application The setting of index and the choosing of data.
But this article put the original data directly into models to calculate the samples, without being affected by subjective factors and artificial empowerment, therefore it can avoid information distortion, and makes relatively objective evaluation results.

Two low carbon steels alloyed with 0.48wt% and 0.78wt% Cr were warm rolled to 65%
reduction at 640°C.
After reheating for 30min at 1050°C, all the samples were warm rolled at 640°C (average strain rates of 30s -1) to reductions of 65% in a single pass on the EMR-CANMET pilot mill in Ottawa, Ontario.
Post-processing of the raw data was undertaken using HKL-Channel 5 software.
Raw data in the form of incomplete pole figures (PFs) (χ = 0° - 80°) from the (110), (200), and (211) crystallographic planes were used to calculate the orientation distribution functions (ODFs).

Another approach, i.e. the measurement of penetration profiles of the radio isotope 95Nb,
provided very accurate data on the temperature dependence of D' for x = H/Nb = 0.05 and 0.06
between 850~950°C, and additional spotty data for higher H concentrations.
Results are shown in Fig. 3 [9], together with reference data on pure Nb.
Resistometry data described above [8] are also included.
Two sets of data by Koike et al. [8] and Iida et al. [9] are shown, together with some reference data for pure Nb.
Data of Koike et al. for x = 0.26 [8] and Iida et al. for x = 0.25 [9] are compared with a model calculation assuming a temperature dependence of the occupation number (shown in the inset).

The porous network structure of RC led to the reduction of ordered crystalline region and the decrease of crystallinity (CrI), which was proved by BET results.
The content data was shown in Table 1.
Table 1 Components content of degummed pineapple leaf Cellulose (wt%) Hemicellulose (wt%) Lignin (wt%) Ash pineapple leaf 81.27 12.31 3.46 0.9 Bagasse 32~48 19~24 23~32 1.5~5.0 Coconut shell 36~43 0.15~0.25 41~45 2.7~10.2 Compared with the data of bagasse and coconut shell, the cellulose content of pineapple was high above others, and possessed the lowest content of ash.
Different from distilled water, NaOH dissolution could penetrate into not only the amorphous region but also the crystal region, which could make the crystal lattice swelling and destroyed, so its intensity and crystallinity index was decreased with the reduction of the ordered crystalline region shown as Table 2.
Due to the remove of hemicellulose and lignin and penetration of NaOH liquid, the crystallinity was decreased from 80.87% to 69.68%, accompanied with the reduction of the ordered crystalline region, leading to the decrease of thermal stability.

This study examines the recovery behaviour of the inter-alloy region between a core AA6XXX clad with AA3003 after 72% rolling reduction.
The measured intensity versus 2 theta data consisting of the Kα1/ Kα2 doublet were read into an in-house program for pseudo-Voigt function fitting and θB determination.
The data shows that there is no discernible reduction in “brass” and increase in “cube” until after 309°C.
For Al, α=0.5 and μ=26GPa, resulting in a shear strength reduction of 3.7MPa.

As an automatic identification and data capture technology, RFID can greatly enhance the visibility of the supply chain and has a significant impact on its’ performance.
Through the recent improvements RFID technologies have made headway in data processing and microelectronic and have broad application in various domains.
Besides labor savings described above such time reduction will result in the processes of loading/unloading, shipping and cross-docking. 3) The ability of real-time communicating and querying can increase data accuracy.
The ability to have visibility of product at retailer locations will provide a level of insight into product performance that is possible today only through external data gathering agencies.
The data accuracy and efficiency provided by RFID system rely on the construction of hardware, software and network Infrastructure.

Fig 1 shows a clear reduction in the strength of the neoprene as aging time increases.
This is accompanied by a reduction in the strain to failure.
It is determined at elevated temperatures and these data are used to extrapolate material performance to ambient conditions.
Average values of the data were shown in tab. 1.The data in table 1 were dealt with by means of Origin 6.1, the results shows that tearing strength of the neoprene decreases with aging time accord with Eq. (3), where SE (J/m3) is the tearing strength, k the reaction rate, t (day) the aging time, b and α constant
