The incubation time becomes shorter with the higher cold rolling reduction.
The calculated apparent activation energy for recrystallization decreases with the increasing cold rolling reduction, indicating that the recrystallization occurred much easier in AA5754 sheet with higher cold rolling reduction.
When the cold rolling reduction increases to 67%, the recrystallization becomes much faster.
The values of k and n were determined by fitting the experimental data (Fig. 7).
In contrast, the curves fitted according to the recrystallization time demonstrate a better agreement with experimental data.

China produces 22179000tce sulfur dioxide for the whole year, from the above calculation, one line subway in Beijing can save 19700tce sulfur dioxide, the assume that there are ten lines subway, the data may be 6-10 times larger.
From these data, transportation may be a section needs more attention to reduce emission.
So except for , other known data stay the same.

The test data show that the beam-reduction and rib-addition strengthening method results in an obvious enhancement of the natural vibration frequency of simply supported hollow slab bridges, which proves that the strengthening method has remarkable improvement effect on the rigidity of bridges.
The study result is that the beam-reduction and rib-addition strengthening method can greatly enhance the structural behavior of hollow slab bridges.
Fig.1 Cross sections of the bridge before and after strengthening (Unit: cm) Test and data analysis Dynamic test.
This is totally identical with the result of the appearance inspection and the conclusion from the static test data.
Conclusions Based on the practical test data from a 30m-span prestressed hollow slab bridge, the natural vibration frequency and vibration mode of the bridge before and after strengthening are compared and analyzed in this article.

Owing to the lack of the datas concerning the mass transfer character of chrome molten slag, the datas from dynamic model of instant and persistent contact reactions established by Robertson were adopted, namely km=2.4×10-3 m·s-1~4.6×10-3 m·s-1 [6].
The model described and resolved the process of chromium ore smelting reduction preferably.

Step 2: partition training sample data: 50% for training, training data equals to ; 50% for testing, test data equals to .
Experiment: Don’t perform any dimensionality reduction on the extracted original 48D speech feature data, and does the emotion recognition experiment directly.
Dimensionality reduction for visualization of normal and pathological speech data.

Because of the increasing demand of the simulation experimental data, the weapons target-injuring efficiency has become a very important indicator so as to be included in the evaluation system.
The variance reduction techniques should be combined with Monte Carlo method.
Simulation of Missile’s Flight Process While the high-speed computer is developing fast, using Monte Carlo Method to estimate statistic data of weapons system has become an important branch of military simulation [2].
Variance reduction techniques The common techniques of variance reduction are: Antithetic Variables Method, Control Variants Method, Stratified Sampling Method, Importance Sampling, Conditioning Method, etc.
We use Matlab to calculate data; 1.

The result shows that the hourly concentration, daily mean concentration and annual mean concentration of NOX in air exceed the standard data, and the affected areas respectively account for 0.2%, 0.18% and 0.12% of the total area of the economic circle.
Whether the emission reduction of NOx of Chengdu Economic Circle can be successful is the key for finishing the task of emission reduction of NOx during “the Twelfth Five-Year Plan” in Sichuan Province.
The NOX emission of the domestic area source in the Chengdu Economic Circle (including all cities in the circle) can be calculated according to the population data of each city, energy data, per capita living energy consumption of standard coal for domestic use, liquefied petroleum gas, natural gas in each city, etc. in the statistical yearbook of Sichuan Province by using the emission factors [5] of NOX in the rural and urban household cooking range measured by Zhang J. etc in 2000 (showed as Table 4).
Therefore, the NOx concentration distribution of the whole economic circle can not be fully reflected only through monitoring data.
Therefore, the emission reduction of the NOx becomes the actual need for the protection of atmospheric environmental quality.

To achieve the goal, the proposed system must provide the following functions: 3D modeling, visualization, segmentation, bone reduction, fixation and data output.
Display of CT data.
The CT data is essentially a sequence of two-dimensional images, which can be represented as a set of volume data where a three-dimensional matrix recording the gray value of each pixel on the images is employed.
For example, the volume rendering technique can only show the surface data of the bony structure as well as its neighboring soft tissues from any section.
Accordingly, the display of 3D isosurfaces data and 2D images simultaneously enables one to catch more information from the CT data.

Rough set data analysis is a symbol method of analyzing relativity and dependence of data.
Continuous data need to be dispersed.
The method of rough set data analysis system actually is the course of reduction of decision table.
Data Discretisation.
The function is logic(xl,x,y) ，xl is original data, x is reduction result data, y is the minimal rule.

Traditional noise reduction procedures (e.g.
Traditional speech recognition systems use a single microphone to collect the speech data to be analyzed.
However, when the environment includes noise, interfering signals, or when a different microphone is used to acquire data than was used to train the system, the system's performance invariably degrades, usually drastically.
The pattern classifier was trained using data corrupted by Gaussian noise.
Noise Reduction With Multi-microphone Recording Multi-microphone schemes use the principles developed for one microphone in various modifications and represent robust techniques for noise reduction.
