Working principle The principle of SAW air flow sensor shows in Fig.1, whose core is SAW delay line sensor, It is a transducer and composed by piezoelectric material substrate and interdigital electrode deposited on the substrate.
Firstly, aiming at air flow detection, the temperature characteristic of piezoelectric substrate material should possess sufficient temperature sensitivity; secondly, the electromechanical coupling coefficient should be high as far as possible to increase the signal-to-noise ratio during signal transmission and processing; meanwhile, piezoelectric substrate material should also have high Curie point to ensure it won’t occur piezoelectric effect degradation under working conditions.
In the article, we selected YZ-LiNbO3 monocrystal as sensitive material of SAW flow sensor, with spread velocity of ν0=3485m/s.The interdigital transducer was placed on the piezoelectric substrate using microelectronic process.

To ensure that the identification task faithfully represented the detection of a fatigue fracture event, preliminary tests were carried out on a small compact tension (CT) coupon of the same material as the landing gear.
The major advantage of this approach is that it is expected to transfer between different materials without difficulty.

Experimental Description Materials and Specimens.
The materials used were cement of type Portland 42.5R, general river sand, crushed gravel (the maximum grain size is 20 mm), and tap water.
Speed of sound in concrete depends on the relative concentration of its constituent materials, degree of compacting, moisture content and the amount of discontinuities present.
This correlated the damage variable with the macroscopic physical quantity of concrete materials and makes the physical meaning of damage clearer.

In the same way, people in the past paid more emphasis and priority on emotion and spirits than on materials.
How do the soft and material systems get function?
We think that the researches to traditional buildings should be related with the surroundings when civil culture, materials, weather, economy, environment, selected mode, lifestyle, public feelings, folkways, local interesting, folk music and other conditions get function.
