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.

The Applications of the Electron Beam Machining Technology in Research of Materials Science Hang Li, Hailang Liu, Haihua Yu, Yiping Huang (Institute of Electrical and Mechanical Engineering, Guilin University of Electronic Technology, Guilin 541004, China) email: 843174150@qq.com, email: liuhl@guet.edu.cn, email: 413810615@qq.com, email: hyp@guet.edu.cn Key words: Electron beam, Materials processing, Surface treatment Abstract.
When electron beam bombards materials, electronic and metal collision lose kinetic energy, most of the energy is converted into heat, cause the local temperature of the materials rising sharply and melting, even gasification and have been removed, so as to realize the material machining.
The main applications of EDM in the field of materials research The application status.

Surface Behaviors of ELID Ground Engineering Ceramics Jianyun Shen1, Weimin Lin 2, Hitoshi Ohmori2 and Xipeng Xu1 1 Provincial Key Research Lab for Stone Machining, Huaqiao University, China 2 Materials Fabrication Laboratory, The Institute of Physical and Chemical Research, Japan Keywords: Ceramic, ELID Grinding, Surface Behaviors Abstract.
Based on the analysis of material properties and detailed micro-observation of ground surfaces, it can be concluded that the material removal mechanism of engineering ceramic is closely related to its mechanical properties.
Therefore, it is necessary to understand the effect of grain size and morphology on the material removal mechanisms of engineering ceramics in grinding processes [1].
Bifano deduced a critical depth of cut for the ductile-to-brittle transition in grinding of brittle materials, and proved that it was closely related with the mechanical properties of brittle materials [6].
Fig.5 Smooth surface of Si3N4 ceramic Conclusions Difference in mechanical properties for engineering ceramic materials should lead to difference in the surface behaviours during ELID grinding process.

Enhanced Piezoelectric properties of Barium Titanate Single Crystals by Domain Engineering 〇Koichi Yako, Hirofumi Kakemoto,Takaaki Tsurumi, and Satoshi Wada Department of Metallurgy and Ceramics Science, Graduate School of Science and Engineering, Tokyo Institute of Technology,2-12-1 Ookayama,Meguro-ku,Tokyo 152-8552 Keywords: d33 piezoelectricity , engineered domain , barium titanate, single crystal , domain engineering ABSTRACT Engineered domain configuration was induced into barium titanate (BaTiO3) single crystals, and the d33 piezoelectricity was investigated as a function of domain size.
INTRODUCTION In ferroelectric single crystals, high performance of piezoelectric properties appears by domain engineering.
These ultrahigh piezoelectric properties were originated from one of the domain engineering techniques, i.e., "the engineered domain configuration"[5-6] "Engineered domain configuration" technique uses the anisotropy of the ferroelectric single crystals. [7-8] BaTiO3 crystal is one of the typical lead-free ferroelectrics.
