Calculation of Angular Variation of Spacecraft Assembly Considering measurement uncertainty Jingzhao Yang 1, a, Guoxi Li 1, b and Baozhong Wu 1, c 1 College of Mechatronic Engineering and Automation, National University of Defense Technology, Changsha 410073, China ayjingzhao@gmail.com (corresponding author), blgx2020@sina.com, cwubaozhong@vip.163.com Keywords: Key Characteristic; Measurement uncertainty; Assembly variation Abstract.
Its basic idea is: a probability model or random process needs to be constructed firstly to make its parameter equaling to the key to the question for the sake of pursuing solutions in math, physics, engineering technology and production management; then the statistical characteristic of the parameter is calculated through observing and sampling the model or process; finally the approximate value of solution is given, while the solution’s accuracy can be explained with standard variation of estimated value.

In addition, through the rational design in a modern car, with application of new lightweight materials, such as high strength steel,1 aluminum and magnesium alloys, titanium alloys, engineering plastics and carbon fiber, rare earth and other polymer and composite material to replace the traditional iron and steel materials would also be of an important ways to reduce the automobile weight, with ensuring high-speed vehicle stability and security of the premise as well as[1].
As well as, we must adhere to the technology path in that, structural design, a variety of materials and manufacturing techniques are integrated, which is the key of resolving the problem of lightweight and security.

Biomimetic Fabrication and Characterization of BG/COL/HCA Scaffolds for Bone Tissue Engineering Chen Xiaofeng, Wang Yingjun, Yang Chunrong and Zhao Naru Biomaterials Research Institute, Collage of Materials Science and Engineering, South China University of Technology, Guangzhou 510640, P.R.China The key Laboratory of Specially Functional Materials and Advanced ManufacturingTechnology, South China University of Technology, Ministry of Education, Guangzhou 510640, P.R.China Keywords: Bio-mimetic synthesis, collagen, bioactive glass, tissue engineering scaffold Abstract.
The bone tissue engineering scaffold was developed by compounded the type I collagen with the porous scaffold of the sol-gel derived bioactive glass (BG) in the system CaO-P2O5-SiO2.
Introduction Ideally, the tissue engineering materials should possess adequate mechanical and biological pro- perties, in the form of highly porous scaffolds to provide suitable microenvironment.
Many suitable materials have been used as scaffolds, including bioactive ceramic and polymers.
The bioactive glass powder was used as the raw materials for the scaffolds.

Finally, the article puts forward three key problems of crop straws, which are used as the building wall materials and thermal insulation materials.
At present, the industrial conversion of crop straws are used as the architectural wall materials, Thermal insulation Materials, etc.
Professor Xiao Li, from Jilin construction engineering college, used straws to develop a new type of straw lightweight insulation block in 2011, and it used broken corn straws as the main material, mixing with cement and surface modification agent.
Crop Straws as the Architectural Wall Materials and Thermal Materials Are Existing Problem Crop straws as the architectural wall materials and Thermal insulation Materials need to consider the question of antiseptic treatment, Moistureproof processing, Mouldproof treatment and so on.
According to crop straws as the architectural wall materials and Thermal insulation Materials, this paper summarizes the mechanical property and thermal performance, and elaborates three key problems of crop straws as the architectural wall materials and Thermal insulation Materials.
