Carbon cluster-like radar absorbing material is a new material designed and developed based on the relationship between structure and vibration-rotation motion levels of planar cyclocarbon cluster.
For example, specification will describe that ducts may be made of galvanized-iron. When galvanized-iron is used, it may be lined with sound absorbing material, to reduce noise from movement of air.
Nature of the electromagnetic wave( EMW) absorbing materials is the energy conversion.
These rods, made of neutron-absorbing materials such as boron, mop up excess neutrons and quench the chain reaction.
Measures to promote the durability of inorganic tunnel sound-absorbing material
The nuclear reaction can be controlled utilizing rods made of neutron-absorbing material, such as boron, essentially shutting down the fission process.
There is a best matched point of chiral spring concentration between3.2% to4.0%, which should be considered when the chiral absorbing materials are designed for wide absorbing band applications.
Conjugated Schiff bases have a potential possibility in producing microwave absorbing materials because of its adjustable electrical conductivity.
Influence of thickness and density on sound-absorption capability of nonwoven sound-absorbing material
As the key of stealthy technology, radar-absorbing material (RAM) has been paid more and more attention all over the world, it has being the hotpot in national defense field after the gulf-war.
This paper reviewed the realization methods of radar camouflage from four aspects: shaping design, absorbing materials, jamming and offset technique.
A new type of porous sound absorbing material was made from super-strength gypsum and glass fiber.
It is an important way with the sound-absorbing materials to improve the sound pollution.
When the as-formed mullite ceramic is used as an impedance transfer layer of the microwave absorbing material, it greatly enhances the microwave absorbing efficiency of absorbing materials.
Al-Cu-based sound-absorbing materials by self-propagating high-temperature synthesis
It has odd angles (reminiscent of a stealth bomber) to reduce its radar cross-section, and was coated in radar-absorbing material.
The present experimental investigation attempts to understand the attenuation of detonation waves propagating through an absorbing material lining section.
Absorbing properties of MnO_2/CB/epoxide resin absorbing materials with double-layer structure
sound - absorbing material and sound - absorbingconstruction
On the other hand, microwave absorbing materials are being used to confront radar detection in military fields.
