Key Technologies and Trends of Passive Buildings Lizhong Shi1, a, Yemin Zhang2, b Institute Architectural Engineering ; Liaoning Province Environmental and Geotechnical Engineering Laboratory, Shenyang University, Shenyang 110044 aslz-0318@163.com, bm1964@163.com Key words: passive house, interdisciplinary field, energy conservation and low carbon Abstract.
The thickness of insulation materials in Germany has gradually increased from only 4 cm to no less than 10 cm regardless of the type of material.
With a thermal conductivity between 0.007 and 0.009 W/(m∙K), vacuum insulated panels provide insulation performance ten times better than that of conventional insulation materials.
There are commonly two types of materials for roof insulation.
The floor insulation thickness is at least 25 cm. 3) Airtightness To ensure the completeness of thermal insulation, key locations including window openings, air conditioning bracket, service penetrations, roof joints and building corners must employ suitable sealing materials and thermal insulation. 4) Thermal bridge treatment To make the thermal insulation systems work well, not only should insulation materials and thickness be carefully selected, but also design and construction of key joints to avoid thermal bridges.

However, to reduce the product development cycle and minimize the number of costly hardware builds, hardware testing must rely on engineering analysis and upfront simulation in the design cycle.
The typical materials for lightness of weight are high-tension steel sheets, plastic, etc. [2, 3].
Key-life test [9] A Fundamental Experiment We executed a tension test to obtain data in the elasticity and plasticity regions of PPF 213-59 TY1=SO-5208, PC-ABS MS214-04=NS-5000, and ABS MS225-18 TY5=XR-474, which are the typical plastic materials used in this study.
As mentioned earlier, the materials used are four types of plastic material (PPF, PC-ABS, ABS, and TPO) and five types of steel material (SPHC, SPCC, STK500, SPFC590, and SECC).

Materials for Devices Applications in Life Sciences G.
The unprecedented technology advancements in miniaturizing integrated circuits, and the resulting plethora of sophisticated, low cost electronic devices demonstrate the impact that micro/nano scale engineering can have when applied only to the area of electrical and computer engineering.
The integrated life chip technology requires the integration of multiple materials, phenomena, technologies, and functions at micro/nano scales.
In addition, we will examine how to modify microfabrication techniques and innovate process conditions for depositing, patterning, and measuring these materials.
Technologies for performing automated, high-throughput protein crystallization screening, and strategies for rational control of protein crystal growth are key engineering challenges for structural genomics and for structural biology in general.

Engineering change is an important and complex activity for manufacturing enterprises.
In order to improve the efficiency of engineering change, we proposed a method of EC propagation in collaboration environment.
Introduction Engineering Change (EC) is one of most important activities for manufacturing enterprises.
Engineering change is essentially a process that is caused by initial change and affecting different constrains.

Application Research Development of Smart Materials on Personnel Armor Protective Materials Jun Liu1, a *, Dang-sheng Xiong 2,b and Bin Li1,c 1The 3rd Department of Suqian College, Suqian 223800, China 2 Department of Materials Science and Engineering, NUST, Nanjing 210094, China a xingzhitianxia@163.com, bxiongds@163.com, clibinnfg6@sina.com Keywords: smart materials; ER; MR; STFs; armor protective materials Abstract.
Now armor protective materials understudied can be made into new adaptive materials by introduction of foresaid fluid.
MRFs can offer solutions to many engineering challenges, whose finding traces back to 1940s earlier than that of ERFs; but only recent decades they reattract attentions of research staff and obtain quickly development.
Among these technologies the key to obtain bullet resistance is a novel use of electrorheological materials.
Other similar smart material applications on armor protective materials.

The collaborative design and manufacturing process reflects the concept of concurrent engineering.
However, the data sharing is passive, which is realized by the way of sending and receiving, so the concurrent engineering is limited.
The system supports the engineering change management which could record the change process and previous version of drawing.
As the suppliers could share the data through the collaborative platform, C919 could be built in the concept of concurrent engineering.
We build the collaborative design and manufacturing system and propose the way to share the data and realize the concurrent engineering.
