The key measures for this technology are energy saving, material saving, water saving, land saving, as well as protecting the environment during construction.
Meanwhile, responsibility engineers were designated to document requirements on material and use plans.
All these analyses above made the engineering geological conditions rather complicated.
Moreover, recyclable construction waste such as waste paper, wood, wire and scrap metal material was collected for other engineering applications by staff specially designated.

A method is proposed for joining materials by means of EBW using an electron beam sweep.
In various sectors of industry, including, first of all, petrochemical, mining and marine engineering, large volumes accrue to products designed to the use in harsh environmental conditions, and this fact substantiates the demand for cold and corrosion resistant steels [6-8] and other materials.
Aluminium alloys hold their niche in the list of such materials in mining engineering.
Currently, to reduce the number of experiments and, consequently, the costs for performing thereof, various simulation methods are widely used during the development of new materials and techniques in different technical fields, including welding engineering [13-16].

Production of bioceramics from natural materials such as bovine and sheep bones with calcination method, is possible.
This study indicates calcination as a simple way of nano-scale bioceramic production for drug delivery and tissue engineering applications.
In order to get rid of all prion diseases (such as mad cow disease) these natural materials should be treated with high temperature calcination method [5, 10].

Introduction Building the architecture of green building is highly complex system engineering.
In order to realize the engineering, environmental engineers and architects must use sustainable design method and the decision makers, management institutions, community organizations have the environmental consciousness, and all participate in the construction process [1,2].
The evaluation factors and sub-factor can be divided into key and non-key.
Therefore, for the environmental standards, after the operation personnel choose the object materials with a clear study goal, then it collect data to judge, and calculate the percentage of waste materials to all materials, and the percentage of high cost circulation material, so as to find the problem in advance and adjust in time

A survey on design trend of 21st century involving 100 contemporary designers and design teams shows that designers widely admit that possibility from new material is a key drive for creating new products in the future [1].
Materials and Sensory Properties Being parallel to engineering properties of materials (such as strength, hardness, modulus of elasticity and so on), the term “sensory properties” of materials we use is its equal [2].
Hence, actually sensory properties of material are a combination of engineering properties or physical properties and subjective reactions and a direct feeling of human organs, which differ from the understanding of material properties measured by instruments [3].
The key to display the sense of beauty of work’s materials is not the value of materials but applying the materials rationally, artistically and creatively.
