Development and present situation analysis of desks and chairs From the point of the material of desks and chairs, its development has experienced the miscellaneous wood made of steel ,wood and hard plastic three phases; from a modeling perspective, they evolved from a single style to free combination of different kinds of forms [3].
There are two keys of the chair design.
The selection and collocation of color and material of the desks and chairs The color design of desks and chairs should not only ensure individual set of desk and chair look beautiful, but also ensure that dozens of sets of desks and chairs should be coordinate with each other in classroom.
The research of primary and secondary school classroom desks and chairs design human-machine engineering in Wuxi [D].

Manufacturability of sheet metal design with the help of Product Data Management (PDM) Merja Huhtala1, a, Mika Lohtander2, b and Juha Varis3,c 1, 2, 3 Lappeenranta University of Technology, LUT Mechanical Engineering, Skinnarilankatu 34, 53850 Lappeenranta, Finland amerja.huhtala@lut.fi, bmika.lohtander@lut.fi, cjuha.varis@lut.fi Keywords: Product Data Management, PDM, Sheet metal design Abstract.
There are, according to Rao et al. [4], three different dividing groups for sheet metal part features: management features, shape features and material features.
Of course each of these groups is including more information about the part; material, drawing number et cetera.
Manufacture friendly product is the key for fast and quality proof production.

Microstructure, Texture and Mechanical Properties of Mg-2.0Zn-0.3Gd Alloy Sheets Fabricated by Large Strain Hot Rolling Jun Luo 1, 2, a, Hong Yan1, b, Rongshi Chen 1, c and Enhou Han 1, d 1State Key Laboratory for Corrosion and Protections, Institute of Metal Research, Chinese Academy of Science, Shenyang 110016, China 2 University of Chinese Academy of Sciences, Beijing 100049, China ajluo10s@imr.ac.cn, bhyan@imr.ac.cn, crschen@imr.ac.cn, dehhan@imr.ac.cn Keywords: Mg-Zn-Gd alloy, Large strain hot rolling, Microstructure, Texture.
Recently, texture weaken effect have been observed in Mg-2.0Zn-0.3Gd alloy (SuperDucMg®) [2] and this alloy made the raw material cost comparable with AZ31 for its trace Gd addition.
Therefore, it is helpful to enlarge Mg alloys sheet application when combined the low price raw material and efficient producing method, e.g.
Fig.4 shows the engineering stress-strain curves of the as-rolled Mg-2.0Zn-0.3Gd sheets along the RD and TD.

Besides the silica spheres, the materials of interest used for the EPSA process for photonic studies can be extended to ZnS, polystyrene (PS) and polymethylmethacrylate (PMMA).
