Crystalline phases were identified using the International Center for Diffraction Data (ICDD) database.
The Rietveld method was used to refine the XRD data using the MAUD program.
The results demonstrated that the replacement of Fe3+ by Al3+ ions and the increase of heat treatment temperature cause a slight reduction in Ms, Mr and Hc, favoring the antiferromagnetic ordering of such systems.

So each child configuration model only includes
the rational configuration data consistent with a specific customer group.
When configuring, we should choose one of these children nodes to replace the parent GM node based on the CRs and rules; ③ -Accessional‖, in consideration of data redundancy and maintenance, we suppose to build GPS model for BGP only.
The size and complexity of the problem will be of much reduction.

Introduction
Aluminium alloys contribute to a reduction of the vehicle mass in current automotive sheet applications in body-in-white (BIW) as well as hang-on parts.
While no comparable data were found for Series 1, the results for Series 2 can be drawn into comparison by data from TALAT [5].

Based on the Stratified summation method in one-dimensional deformation assumption and code for design of building foundation law in Engineering[2], but the one-dimensional compression is only a special case.Soil geometric and force are mostly three dimensional, although the <

In the formula, , was not loaded and loaded after the void ratio Put Eq. 5 into Eq. 4, we can get Eq. 6：
(6)
Put Eq. 6 in to Eq. 3, we can get Eq. 7：

Consequently, the measurement update interval (MUI) may be limited by the rate at which measurements are available, by the data processing power of navigation computer, or by the correlation time of the measurement noise [2].
For the reduction of computation load, numerical values of some parameters in the modeled system are predetermined before applying the analytic approach.
To confirm verification accuracy of the proposed analytic method, sample time of the INS measured data is 2 ms.

Introduction
Focus on cost reduction in producing advanced composites systems has increased and leads to an interest in Fe based matrix composites.
The recorded spectrums were matched in accordance to the data from the ASTM Powder Diffraction File.
All the weight loss data were converted to volume loss using the measured densities.

Sufficiently high blade vibration frequencies result in rapid accumulation of number of stress cycles and therefore in blade failure, especially if there are some factors of fatigue resistance reduction: corrosive or erosive damages, dints, material defects, structural stress raisers, residual stress in material surface layers etc. [2; 3].
Direct measurement of blade dynamic stress in an operating turbo-machine (for instance, by strain-gage testing) allows obtaining reliable data, but such procedures are quite difficult and labour-intensive [4].
, we obtain (5) where On multiplying equation (1) by х3 and integrating within the same limits, we obtain (6) where (7) Since we are developing new technique for experimental data processing, we can select those geometrical parameters of test samples which simplify experiment and its analysis (with necessary measurement accuracy remaining).
