Lithium compounds find widespread applications in secondary batteries (rechargeable batteries) as cathode materials (e.g.
LiFePO4, LiCoO2, LiMn2O4, LiNixCoyMnzO2) as well as in primary batteries (single-discharge batteries) as anode materials [6].
There exists, therefore, no longer a difference between primary and secondary raw materials.

It is commonly alloyed with aluminium, tin, and vanadium to produce strong and lightweight materials [3].
A magnetic field close to the maximum capacity of the equipment was chosen to guarantee that all magnetic material was separated, since due to the small amount (in terms of mass) the magnetic material could be dragged with other non-magnetic materials present in the black sand.

Application of titanium dioxide photocatalysis to create self-cleaning building materials.

Materials are sent to storage silo through conveyor belt.
Materials are weighed by the sensor after they are sent to weighing silo.
Secondly, materials are dropped into packaging bag from emptying silo after weighing.
Before system starts working, touch screen can select the corresponding parameters of different materials to achieve better control precision.

Because the smart materials have excellent mechanical performance, the structure vibration control applied them is focused on recently.
One class of such material is shape memory alloy (SMA)［2］.

Provide the method for improving testing accuracy of green high performance concrete strength testing by rebound method. 1 Meaning of Rebound method test the strength of green high performance concrete Concrete as the most major manmade materials, it have a big demand for resources, and have very huge influence on protecting the environment.
How long-term be Concrete, as a major building material, key lies in how it become a green materials.
Analysis thinks, for realizing the liquidity pumping concrete, increased gelled material ratio, increased sand ratio increases, gravel size is small, that reduced surface hardness, and make rebound value slants small.
Considering the influence of slump in test the strength of concrete by rebound method, plastic concrete and pumping concrete must respectively established detection strength curve. 3.Test analysis prove: raw materials, mix proportion, early maintenance methods of concrete strength, surface hardness and carbonization speed has great influence, concrete carbonization phenomenon has significant influence to test concrete strength by rebound method, not allow to ignore, therefore, carbonation depth value as an independent variable in detection strength curve.

A nation can purchase the necessary materials from other nation and the condition that primary elements are not limited in Von Neumann is adaptive.
If a nation can firstly get the quantity and scale of the national economic system in the next year and afterwards purchase the required material, the production of a nation will decrease the storage and production cost.

Fig. 2.The finite element model of the girder Fig. 3.The virtual prototype of beam-carried crane with flexible body Dynamic Analysis Results During the application of Beam-carried cranes in engineering construction, the load for the girder consist of both impulsive load and periodical alternating load for wiggling movement of heavy material.
Where is the mass of the lifted material, here ; is the acceleration of gravity, here ; is the coefficients, here ; step(*) define step function response from 0 to 1 within 0.2s.The simulation result of the displacement for the girder’s centroid with step load was shown in Figure 4.
And they can be derived by formula listed as[5]: , , So the transfer function of the girder’s vibration system can be got as: (3) Sine Response Simulation.According to lifting height in design, the frequency span of lifted material is 0.5~2Hz.
