System of Aviation Supplies Inventory Modeling Introduction of aviation supplies’ operating process The Civil aviation enterprise must be followed a lot of regulations.
As the civil aviation enterprise normative operation, the "Maintenance and Production - Inventory- aviation supplies Supplement” system can be taken as a general physical system, shown in Fig.2, which provides possibility for aviation supplies inventory control strategies by the engineering control theory. [3] On other hand, aviation supplies inventory system is an uncertain system.
The result shows: (1) From the engineering point of view that the number of different dates tire consuming is independent of each other and the correlation of different date loss is weak

Test methods System test researches of the strength and expansion rate on the full weathering granite under the different compaction conditions were made according to code for soil test of Railway Engineering (TB10102-2004).
The liquid plastic limit test of plain soil and improved soil were strictly done according to code for soil test of Railway Engineering ( TB10102-2004).
(1) Summary In the tests, we can find the engineering properties of yellow weathered granite are slightly better than that of the red one, that of the grey one is the worst.

To get the exact results, you need to solve several higher order differential equations, and it is much difficult for actual engineering designs.
Full span uniform torque, cantilever (refer with Fig. 4) Boundary condition: ,,, calculate and get: (7) Simplified calculation of , , in engineering design Obviously, for calculation of internal force in torsion in different working condition, if using equations (4) to (7) to calculate, it will be very complicated in real project, and is not convenient.
Hence, the internal force and stress in torsion in real engineering design should not be ignored.

Salama proposed using modal kinetic energy as a means of ranking the importance of candidate sensor location.This method has been used in the field of aviation[4]，large scale civil structures[5]{Meo, 2005 #25}.There have also been several variants on this theme,such as average kinetic energy and weighted average kinetic energy(WAKE)proposed byChung and Moore[6].However, modern finite element models have become so refined that the mass is smeared very evenly over the structure, making it difficult to selected important degrees of freedom based on mass weighting.
QRdecomposition method is a modal matrix column vectorswith the norm of rows, to sortrows to find linear independent ones.The aerospace[7],automotive[8]and civil construction[9] applied this method.
