Digital protection based on reverse engineering Reverse engineering is refers to that the product was obtained from the actual sample and get the relevant technology of the new product manufacturing.
In order to achieve the effective mass of 3Ddigital workflow, complex irregular shape using reverse engineering scheme, as shown in figure 2.
Reverse engineering can be divided into data acquisition, data processing, surface reconstruction and other key technology.
Data acquisition is the first step of reverse engineering CAD modeling.

It's the cause for many failure accidents in soil nailing support engineering.
But it was often neglected in engineering design and construction.
Engineering application of this technique has been for more than 10 years[1].
It is engineering favor in foundation pit supporting and slope reinforcement.
Soil nailing steel materials were II grade rebar.

Second, it is aimed at train applied and composite talents on high-level engineering technology and engineering management and puts more emphasis on engineering practice.
Intuition and inspiration is a psychological phenomenon which is based on logical thinking and closely connected with creativity and it plays a key role in creative activities.
Since Master of Engineering is applied engineering talent, engineering practice will be needed to accumulate practical experience for future service in medium-sized industrial and mining enterprises.
Institutions of Master of Engineering can build practice bases.
Establishing a Scientific Evaluation System of Master of Engineering.

Finally, there was an outlook for the development prospect of such energy materials and its power generation technology in China.
By taking briquetting fuel technology, the dispersed raw materials (mainly in agricultural and forestry residues) with uncertain shapes can be compressed into briquetting fuels with a certain geometry and lager density through processes of drying, chopping and briquetting, etc.
According to different heating positions for raw material, heating action to raw material can be divided into two kinds, i.e. heating at briquetting position only and heating respectively before putting raw materials into compressing mechanism and at briquetting position. (3) For common briquetting, namely forming under normal temperature and moisture condition, after corruption to a certain extent, fiber comes to be soft, wet, cracking and partly degraded, at which time it is easy to be briquetted; then extrude water out from the partly degraded agricultural and forestry residues with a simple die, thus the briquetting fuel can be got.

Fabrication and Characterization of Nano-Hydroxyapatite / Poly (D, L-lactide) Composite Porous Scaffolds for Human Cartilage Tissue Engineering L.Cheng1 , S.M.
These results suggest that the PDLLA/nano-HA porous scaffolds are promising candidates for cartilage tissue engineering application.
Introduction Hydroxyapaite (HA) has been used as tissue engineering material for cell culture and tissue repair due to its excellent biocompatibility and osteoconductivity [1].
And there is much increase in protein adsorption and osteoblast adhesion on the nano-ceramic materials compared to micro-ceramic materials.
