Data Resource of Prevention Rule integrated analysis is proposed which using the two data sources from the civil aviation flight terms and the questionnaire from resourceful pilots.
The Obtain of Experimental Evaluation Data Provided by Experience Pilots.
There was untruthful data from the questionnaire from resourceful pilots because some pilots’ carelessness owing to their hard work, so it is important to clean those false data, noise data, redundancy data and incomplete data.
At last, it is to keep the data integrated, facility and timeliness, to repair those data according to statistic method for those two kinds of properties values [5].

296 Effect of Rolling Temperature, Reduction and Alloying Additions on the Texture of Warm Rolled Steels M.
Two warm rolling temperatures (640 and 700ºC) were employed together with a reduction of 65%.
A reduction of around 65% and two rolling temperatures (640 and 700ºC) were employed.
The steels were rolled to a reduction of 65% at 640ºC and at 700ºC.
Orientation distribution functions (ODF's) were calculated from the pole figure data, to an expansion of Lmax=22 [14], using Bunge's series expansion method [15].

The unique advantages of GPRS are: packet switching possesses resources only during the period of sending or receiving data, billing method is more scientific and reasonable according to data traffic as the standard; provide reliable 115 Kbit/s transmission rate and meet the requirement of real-time; quickly and timely connect with short access time; Once activated, remain activated online status; send messages without having to reconnect again; When sending data, first decompose packet into several pieces of data, and then transmit store-and-forward way, until the receiver again combine reduction data; Provide a complete communication based on TCP/IP protocol, which would wireless access to the Internet and other global network anytime anywhere, and truly realize mobile office.

In addition, good fits to the experimental data were found using the proposed residual strength model, with the maximum difference of less than 6%.
Comparing the remote tensile strength at each moisture content, it is observed that a reduction in the area of 20% (notched specimens) has led to strength reduction of maximum 51%.
After prolonged ageing, a maximum of 17% strength reduction was observed.
In addition, good fits with maximum difference of less than 6% were obtained by using the proposed residual strength model to fit the experimental remote tensile strength data.
This model has the advantage of reducing the amount of experimental works and more data is needed to further validate the applicability of this model to other materials.

Al2O3-Ti(C,N)composite ceramics were prepared by in situ aluminothermic reduction and pressureless sintering.
It can be seen from the figure: the aluminothermic reduction nitridation was incomplete at 1200˚C, AlN and Al2O3 were in eutectic, while only TiN was generated.
Fig.1 XRD analysis of Al2O3-Ti(C,N)composite ceramics sintered at a different temperature Under conditions of this experimental, Al-Ti-N-C-O system may have generated nitride with TiN, AlN and carbides with Al4C3,TiC due to gas diffusion,and the main reaction and are as follows (thermodynamic data from reference [7]: (2-1) (2-2) (2-3) (2-4) (2-5) (2-6) The equilibrium temperature of reaction (2-1) and (2-2) are 3915K and 3156K respectively.The two reactions can occur simultaneously,and the test temperature is far lower than the equilibrium temperature, so the of the reaction is much less than 0, the positive reaction is very strong.The reaction (2-1) has priority to reaction (2-2) by the diffraction pattern.
At 1300℃ the porosity of T2 composites are the minimum because the aluminothermic reduction and nitridation was carried out fully at this temperature, at the same time,TiN and TiC were in eutectic and generated Ti (C, N).

Herein, hexagonal Ni micro/nanoplates were synthesized by a facile hydrothermal reduction route in aqueous solution with the assistance of polyvinylpyrrolidone.
The N2H4·H2O has the strong reducing ability, but its reduction reaction with Ni2+ has been confirmed to follow such a route: Ni2+ + 3N2H4 → [Ni(N2H4)3]2+; [Ni(N2H4)3]2+ + N2H4 → Ni↓ + 4NH3↑ + 2N2↑ + H2↑ + 2H+.
By means of the N2H4·H2O reductant and PVP additive, the hydrothermal reduction route has been verified to be effective way for the controlled synthesis of hexagonal Ni plates. (2).
In comparison with the magnetism data of other Ni materials the coercivity of hexagonal plate-like Ni powders has greatly increased.
