The materials transportation system with storage bin is widely used in mines, power plants, material yards, and etc.
Introduction In some materials transportation system, storage bins are often set.
The block diagrams of the materials transportation system with storage bin.
(1)When links ahead of bin 1 are in failure, links behind bin 2 can continue transporting materials of bin, The maximum value of materials of bin is designed bin capacity Q tons.

The metal materials play important roles in the area of the industry.
As we all known, the structure of the materials’ organization affect the using properties directly.
In the condition of active service, most materials losing efficacy begin on the surface.
Comparing with the common materials with coarse grain, the nano materials are with super high strength, super high hardness, good ductility and other excellent properites.

With the continuous development of Chinese science and technology, structured ultra-light porous metal materials are a new type of multifunctional materials that have emerged with the increasing demand for diverse materials preparation and machining technologies in recent years.
Porous metal materials are materials that are good for the environment.
In addition, with the rapid development of science and technology, we have more scientific and technological means, and thus have greater ability to develop and research new materials.

In order to understand the effect of these materials, test LED samples were prepared with different sets of packaging materials.
As a very important part of LED compositions, packaging materials are sensitive to high temperature.
Thus, the failure of packaging materials is one of the most important reasons of lifetime reduction of the whole LED models.
In order to discover the failure behavior and principle of packaging materials, some typical samples which were the LED modules with common packaging materials including phosphor and silicone were used to undertake high temperature aging test.
By the means of measuring the luminance of samples online, the failure process of packaging materials had been revealed.

The friction materials have many species and they are being used widely, but people have higher requests to friction materials with the development of technology.
Introduction Adhesive is an important part of the friction materials, it play bonded overall load and balanced action of the load transfer in the fibers of friction materials [1-3], it also direct influence on the friction and wear properties and mechanical properties of the friction materials.
Experiment method Prepare the friction materials of the second adhesive.
