Introduction Rare earth elements are widely used in luminescent materials, magnetic materials, catalytic materials and superconducting materials due to their unique 4f electronic shell structure.
Therefore, they could be used in televisions and computers as a substrate for up-conversion luminescent materials of rare earth luminescent materials.

Ecological aesthetics is an emerging interdisciplinary applied science, its theoretical guidance is ecological worldview and the ecological and cultural concepts, and it also possesses strong academic pioneering.
A good ecological system must follow the natural circulation of materials and energy conservation, sustainable development of the basic requirements of human society, in fact sustainable development of the basic spirit is the above-mentioned coordination and long-term nature.
If the building design and construction process damage such coordination, ecosystems, material recycling and energy conservation will be broken, which also destroyed the conditions of life persists.

From equation (1) to (3), it is shown that dioptric power for single lens is a function of radii of curvature, axial lens thickness and refractive index of material used.
Analysis on influence factors for refractive property From above models established, one can see that refractive property can be affected by many factors when two or more lenses are combined together, such as lens structural parameters, material used and lens space.

Therefore, if microphones were used in such harsh conditions, they should be specifically designed for such purpose [8] or placed in large T-boxes filled with an appropriate material [9].
It suggests that either the accelerometer sensitivity is rather low or the vibration suppressing material used between the metal plate and the duct wall should be investigated more thoroughly.
