While, Traditional slicing methods in the rapid forming process always produce ‘staircase’ or additional support structure which reduce deposition accuracy and efficiency, bring about the dissipation of materials.

By means of acoustic data to make a quantitative analysis of architectural history, it will in theory broaden the research domain of architectural history and lay a solid foundation for Chinese religious soundscape science, and in practice, will support the protection of the acoustic environment of historic buildings as intangible cultural heritage, and provide sound field parameters for the construction of a new temple.
As a result, Buddhist temples become good material carrier for ancient Chinese architecture study in modern times.
(2) Studies on the traditional architectural acoustics and soundscape The domestic contributions of acoustic research mainly are from Chinese Academy of Sciences Institute of Acoustics, Nanjing University, Tsinghua University, Tongji University, Harbin Engineering University, Northwestern Polytechnical University and the Shanghai Modern Architectural Design Group acoustic Zhangkui Sang Design Research Institute and other units.
His researches have discussed the differences between the soundscape with the traditional Sound Environmental Studies and Landscape Architecture, which made up for the deficiency of traditional landscape studies that they only consider the visual landscape, and ensured soundscape study to be a basic study in China’s Habitat Environment Science, and made great contributions to the development of soundscape study in China.

Abstract
SEM observations and Vickers-hardness tests were performed to identify the irradiation effects. γirradiation effect during the aging hardening
process can be explained depending on the
composition of the alloy and is used to derive quantitative information on the kinetics of the
transformation precipitates.
γ-irradiation probably play the key role in defects responsible for material strengthening and embrittlement.
Therefore, γ-irradiation probably play the key role in defects responsible for material strengthening and embrittlement.

Introduction
Materials with body-centred cubic (b.c.c.) structure is generally hard to deform at low temperatures, which leads to a brittle fracture while they become easy to deform plastically with increasing temperature, resulting in ductile failure.
The primitive dislocation glide process of silicon crystals is the same as that in b.c.c. materials because of their high values of Peierls potential.

So these are concerned with such things as materials science, superconductivity, microelectronics, optoelectronics, sensors and micro-nano science etc, they have been extensively investigated and utilized up to now.
One of the representations being studied widely is called C60, and the results of C60 are especially important in the superconductors, optical materials, functional materials and biomaterials.
Fig. 3 Transmission coefficient - Energy spectrum in atomics lines C60 model Fig. 4 I-T curve for C60 single-molecule system When C60 contacts with metal atomics line, the interfaces of these two materials will form a barrier, the barrier height is closely related with materials and temperatures.
And we can choose some different atomics materials in order to make unequal current ratio values.
Actually in order to make the device work better, we should select the appropriate Fermi temperature of working materials that is so necessary.

Introduction
The mechanical, magnetic, electrical, and thermal properties of several materials can be modified without necessarily changing their chemical composition, with a simple change of the molecular structure.
In this sense, it is important to study the factors that influence the change of the internal structure in a certain material, therefore from the control of the involved variables, materials with superior properties, smaller specific mass and better corrosion, oxidation, wear resistance can be obtained [1].
Thus, the knowledge and the control of the involved thermal parameters are very important in Materials Engineering, once the temperature levels and the cooling rates are deterministic to the specification of the properties that the material will attain after the thermal treatment [3].
