Problems that cause fire in construction tunnel are common,such as the prevalence of combustible materials, confused electrical lines and the limited fire safety conditions[1].
Xu Qingkun , from University of Science and Technology of China, has done some research about regularity of temperature and smoke concentrations in under construction tunnel which used force injection[2].
Conclusions Due to stacking of construction materials, Electrical Equipment, the probability of fire disaster is high in under construction tunnels.

Low-carbon construction, throughout the life cycle use in construction materials and equipment manufacturing, construction and construction reduce fossil energy use, energy efficiency and reduce carbon dioxide emissions.
In 1999, the UIA 20th meeting, with “21st-century architecture”, which issued the “Beijing Declaration” that “the development of comprehensive utilization of a variety of architectural elements in order to meet the full needs of the phenomenon of human settlements, take the road of sustainable development concept is based on the new architecture of development towards the 21st century, which will bring another new construction campaign, including science , technology , art and creation of the construction.” [3] Today's global trend of sustainable development, ecology and sustainable development will become the common theme of Architectural Education.
Increase energy efficiency and construction architectural theory and design of sustainable development-related courses; in the original creation of “construction physics” course, based on the addition of “construction blocks”, “Environmental Psychology” and “ecological design and technical architecture” and other courses Initial construction of low-grade curriculum of increased environmental awareness, awareness materials, construction and other related topics of teaching cognitive.
Whether in the cultural, social, or in science and technology, the development trends of architecture and architectural education is Consistent with the world, which is diversified, regional differences and ecological and sustainable development direction, Among the historical trend of the world architectural education.

Ibrahim Physics Department, Faculty of Science, Minia University, Minia, Egypt Keywords: Electrical Properties, PbS Thin Films, SCLC, Thermal Evaporation, XRD Abstract Lead sulfide (PbS) thin films were prepared by thermal evaporation onto glass substrates from PbS powder.
Introduction Lead sulfide (PbS), an important member of the chalcogenide materials, is of interest in a variety of applications including IR detectors and solar cells, due to its small band-gap (0.4 eV) [1].
In addition, its relatively large Bohr exciton radius (~18 nm) makes it an attractive material for the fabrication of quantum confinement structures.
Recently, PbS crystals have demonstrated highly efficient multiple exciton generation (MEG), making it a potentially attractive material for nextgeneration solar cells [2].

Introduction Along with the high-speed development of science & technology, the increase of quality and accuracy is a general tendency that can be observed in manufacturing.
The need for high accuracy machining and for high efficiency machining of difficult-to-machine materials is making the application of abrasive technologies increasingly important.
Same time, material removal rate, grinding force decrease gradually in backward grinding, so we can obtain good grinding face.
