In the cloud computing security model, authority management and identity authentication is must done, being conducted to ensure that only people who have relevant permissions to access the Hadoop data; network threat defense is setted up, which realizes intrusion protection; Data encryption is done to prevent data theft; Ensuring the integrity of the data ensures the data will not be tampered with; virtual technology is used to realize dynamic management of material resources and protect the safety of cloud environment., cloud computing security policy model based on the structure of the Hadoop can be obtained on the above of protection strategy.

While in FDR, the sweep signal is inputted to the wire under test and by the Fast Fourier Transform (FFT), the measure data of its reflected signal can be turned to the information in the time domain where the fault distance will be calculated according to the relative propagation velocity which is different in different materials [1].
The interface of a result of the data query Conclusion The data system of wire fault diagnosis in aircraft engines denotes the traits of its capability demonstrated as follows: first of all, it has the ability to meet the objective require of fault detection; secondly, the information of wire parameters in the database holds the authority because it is sorted with widely collecting materials and attained with consulting the experts; thirdly, the easy-to-understand query interface can satisfy the search of the maintenance personnel at all levels; at the end, it is convenient and easy to take the research of the data, and it can also save time and labour for the maintenance.

In the process of attempting to making the sample of the product, technology improvement and material optimization can not only make motor completely reach the required performance indexes, but also reduce the winding copper quantity and the cost in contrast to the same sample machines.
The purity of copper and silver in commentator material is lower, in which the content of silver is small, giving rise to the large friction coefficient and the acceleration of brush’s wear and tear.
Through experimentally comparing the finish turning, grinding time, pressure, and stone materials of the commentator, the best solution is chosen, making the roughness reach 0.24-0.4.

Inoculation cultivation method Inoculation culture method is to add a part of anaerobic bacterial-sludge or large amounts of methane bacteria materials on anaerobic digestive tank to culture.
As the methane bacteria to grow continuously, that can make more use of materials such as carbon dioxide, acetic acid to produce methane, which lead to the anaerobic digestive performance of the whole system gradually stable.

Introduction Conventional accelerometers are made on silicon wafers [1-17], some of them used the thermal convection technologies, and the chamber is filled with the materials such as: air, CO2, liquid, or others.
Step 6: Use the same method to deposit a layer of chromel alloy as the basement material of RFID antenna, and the conductors connected to the power supply.
Besides, the thermal isolation capability is better than silicon with the plastic material, thus the cost of power dissipation for long time operation is lower for the new design.
