The addition of kinetic energy may be needed to move material from one point to the next or to agitate the material.
In rotating equipment solids, liquids or other materials shift through a mechanism of drivers like engines, turbines, motors, driven elements like pumps, compressors transmission elements and auxiliary equipments [2].

Introduction Nitrogen (N),as a detrimental element in superalloys,is not easily removed even during vacuum induction melting (VIM), and usually is controlled by selecting raw materials for minimizing the N level [1].
For getting the virgin alloy, the purified raw materials were melted at a temperature of 15800C for 10min, and then cast into metal moulds in a vacuum of 0.01 Pa to get the virgin alloy bar stock with the weight of 130kg.
Tensile tests with a strain rate of 2×10-5 s-1 were conducted on an AG-5000A Tensile Machine at room temperature and on a DCX-25T Material Testing Machine at 9000C, respectively.

Titanyl sulfate (TiOSO4) is particularly attractive as a raw material for TiO2 production owing to its low cost and lower volatility than TiCl4.
Experimental Detail Materials and preparation.TiOSO4 solution was obtained from the leaching of Bangka Indonesia Ilmenite through sulfuric acid route.

With this definition, we can draw the following unusual conclusion: wastes still retain certain characteristics of raw materials and as such, they can and should be used to produce new products or energy [3].

The material flows into the forming area.
Bending different profile cross sections as well as various bow shapes with the same tool as well as using the formability of the material are the main advantages of this manufacturing process.
Incremental parameters such as distance and angle are limited by the materials tensile strength.

(2) Where n represents the number of types of building materials; represents the total weight or number of the -th building materials, represents the -th building materials’ EEEF intensity; represents the -th building materials’ attrition rate in the construction process
(3) Where n and have the same meaning with them in equation (2); represents the -th building materials’ transport distance from production area to construction site; represents the transportation EEEF intensity of the -th building materials; represents the total weight or number of the -th building materials in demolition process; represents the -th building materials’ transport distance from demolition site to disposal area; represents the transportation EEEF intensity of the -th building materials from demolition site to disposal area .
Therefore, the original building's material retention rate η (the ratio of amount of retained material in the process of adaptive reuse to the amount of original building materials) is introduced.
Construction the model of As lack of statistical data, it is assumes that the average recovery rate for building materials after the main structure of the building was demolitioned are 90%, 50%,20%,10% and 0%for metal, brick, wood and cement and other building materials, respectively.

Gjøvik Olympic Cavern Hall in Lillehammer, Norway Expression based on the local materials.
For the expression method, on the one hand, it is a method to extend and develop the traditional local materials, which reproduces the textures and colors of the traditional materials; On the other hand, it has deeply analyzed the spiritual connotation in the traditional local materials, and uses new technical method or modern materials to inherit the local characteristics.
It is preferable to select the local materials, and pay attention to inheriting and protecting the corresponding architecture technology.
