Measures Analysis of Energy Saving Reconstruction for Existing Building Windows Jianping Liu a, Xuefang Zhao b School of Architecture Engineering,Shandong University of Technology, Zibo,255049,China a liujp@sdut.edu.cn, bzhaoxf79 @sina.com Keywords: Existing Building, Energy Saving Reconstruction, External Window, Measures Analysis Abstract.
According to the statistics show that the heat loss through the outside doors and windows account for about 50% of the overall building energy consumption, the weak link of the heat consumption and energy-saving key positions.
Which reduces cold air infiltration is the principal means of use of new materials, new technologies for serious parts of cold air infiltration to be sealed; The ideal way to increase the thermal resistance is to increase the number of layers of windows, and glass layers, or with new types of glass such as laminated glass, heat-absorbing glass, heat reflective glass and low-e insulating glass.
Windows for energy saving once and for all and the effect of the most significant way is to directly will be the demolition of the original high-energy outside windows replaced with energy-efficient window, such as hollow glass, plastic windows, or use after breaking heat, the thermal conductivity of the metal frame material, steel, aluminum, wood and other composite materials, window frames, window glass can be used in insulating glass, heat reflective glass, heat-absorbing glass or coated low-e glass.

The yield stress of steels is in general influenced by hardening, but the ratio of approximately 2.8 between surface hardness and current yield stress is true from initial state to fully hardened material.
This allows to determine the plastic surface deformation field in the contact zone directly from the gap equation (8). upl = −hmax + h − uel + uo (9) This algorithm reduces the surface height locally by removing material, which means it is not volume conservative.

Experimental Procedure Materials.
The microhardness values decrease with increasing depth from the top surface and approach the hardness values of bulk material (340 HV for 20MnCr5) as seen in Fig.3.
It should be noted that better accuracy in MQLAH gears was observed despite carrying out hobbing at higher speed and feed combination which resulted in almost 25% high material removal rate as compared to FLAH.

Synthesis and properties of thermo- and pH-sensitive poly[(Sodium humate)-(N-isopropylacrylamide)-(Acrylic acid)] intelligent hydrogel Xiaomi Zhoua Xiaoran Sunb Guangyue Lic (College of Chemical Engineering, Hebei United University, Tangshan Hebei China 063009) azhouxiaomi201212@163.com bxiaoranhb@yeah.net cgyli@heuu.edu.cn Keywords: Inverse suspension; Thermo-sensitive ; pH-sensitive; Intelligent hydrogel; Abstract.
The hydrogels have been utilized in a variety of applications such as water treatment, separation extraction, drug delivery[3,4], and tissue engineering.
Since the polymerization is directly affected by many factors, we focus on the study of the key parameters such as mole fraction of span-65 in mixed monomers, concentration of monomers and crosslinking agent, and polymerizing temperature.
Materials and methods Materials.
If the dispersant used in the system is improper, the balance of the emulsion system will be destroyed and the formation of absorbent polymer material will around the stirring rod or sticky wall.

The formability of stamping products is generally determined by the factors including the structure of die, the material properties, the shape of initial blank, the blank-holder force, the layout of draw-bead, lubrication condition and so on [2].
The material of the product is cold-rolled steel plate ST13 with the thickness of 1mm.
Secondly, the draw bead is a key factor in forming this complicated automobile part, which we must take into account.
The draw-bead can provide more resistance to the sheet metal flowing into die cavity, control the flow rate of material and improve the plastic deformation degree [8].
