Introduction Solar energy, the high-temperature solar thermal heat absorption is the key component selection, and solar energy, the heat conversion device is the long-term stable operation, the choice of endothermic components play a decisive role, but also improve the energy conversion into high-grade core technology.
Analyze the reasons, using adhesive pressure seal manufacturing process endothermic components in the200-300 ℃, under a long run, to heat or freeze occurs when the materials are different degrees of chemical reaction, so that the formation of glial membrane deterioration, resulting in objects connected to a gap, falling eventually lead to failure of the vacuum tube, tube surface heat, reducing thermal efficiency, ambivalent, if not more serious collector, on the contrary, play a cooling role.
Second, the heat output is transmitted through media, but media is generally the most common water and oil, all kinds of heat transfer medium in the heat transfer process has often come into contact with adhesive sealing surface of the material composition of the adhesive corrosion, oxidation is vacuum leak that lead to the end of the main reasons cannot be used. [1-3]We propose a new type of vacuum tube that is curved in the traditional straight-through vacuum tube based on its significant improvement to retain the advantage of making production process change, improve the sustained vacuum, reduce heat loss and increase thermal efficiency, solar energy , the high temperature energy collector grade, maximum use of solar energy resources, to achieve technology industrialization.
Manufacturing · With 3.3 high borosilicate glass material, [7]the arc-shaped flat blank made of glass pull technology, further processing will be produced on both sides of the port some distance from end to prepare for and increase in special alloy welding area, and then by going from quality water to clean dry reserve.

Research of Using Sodium Alginate Fossilization Sphingosine Sphingomonas Strain Pellet to Degrade COD of Cultured Seawater in Rizhao Pinghua Zhu 1, a 1 Department of Chemical Engineering, Huaihai Institute of Technology, Lianyungang, Jiangsu 222005, China achenwenbin111@sohu.com Key words: degradation; sodium alginate; Sphingol Sphingomonas; COD Article ID: CLC number: X712 Document code: A Abstract: The sodium alginate fossilization Sphingomonas strains have double features: the biological absorption and biological degradation.
Embedding method has features of operating simple, maintaining the multi-enzyme system of microbial cells and having less effect on microbial activity; from the medicines, equipment and materials used in the experiment, we can see that this method requires less equipment and lower prices, the treatment effect is obvious, and has little pollution on the original water.
Low speed would lead to lack of oxygen therefore limited the on the microbial removal of reducing material, making water and micro-organisms could not contact completely.
Comparison of COD degradation effects of microorganism embedding or not Embedding adsorbent Adsorption capacity（mg/L） Adsorption rate（%） COD of seawater after（mg/L） Embedding microbes 18.1 85.0 3.2 Not embedding microbes 1.2 5.63 19.1 Pure strains 13.2 61.97 8.1 (The initial COD concentration of water samples was 21.3 mg / L) Thus, micro-organisms play a major role on degradation of COD; as a natural polymer material, sodium alginate has biodegradable and biocompatibility, as its structure contains absorption functional group, it has a certain degradation of COD [14].

Materials and Methods The motion of magnetic particles within the body is mainly controlled by the combination of magnetic force and a hemodynamic drag force due to blood flow.
Permanent magnets are compact, low maintenance, and low cost, and it has been proved that they are the most suitable material for compact MDT instruments despite their field weak relative to electromagnets and superconductors.
The magnetic material was assumed to be NdFeB-38 (permeability is 1.049, coercivity Hc=911 kA/m), assuming a linear B vs.

Evolution of Microstructures and Properties of the AlxCrCuFeNi2 High-entropy Alloys Shengguo Ma1, a, Zhaodi Chen, and Yong Zhang1, b 1State Key Laboratory for Advanced Metals and Materials, University of Science and Technology Beijing, Beijing 100083, China amashguo.cumt@163.com, bdrzhangy@ustb.edu.cn Keywords: High-entropy alloy, Heat treatment, Cold rolling, Vickers hardness, Tensile property.
Numerous experimental results reveal that HEAs have good thermal stability, excellent wear and corrosion resistance, promising high-temperature properties, rendering them potential candidates for future engineering materials. [6-15] As we know, the properties of alloys strongly depend on the alloy composition, and the HEAs are not an exception.

A Study on Universities’ Architecture in 1950-60’s ——Xi’an as the Model Min Zhang School of Architecture and Civil Engineering, Inner Mongolia University of Science and Technology, No.7 Aerding Street, Baotou, Inner Mongolia, 014010, China zm8124@126.com Keywords: 1950-60’s, Xi’an, Universities’ architecture, Cultural heritage, Protection Abstract.
In the course of redistribution of productive forces, Xi’an became the key area of Third-line Construction.
In the paper, by means of a host of materials [4,5]and field investigations, there were thirty-five colleges and universities of Xi’an in 1950-60’s, as shown in Figure 2.
The plans should describe the protection value, delimit the protection domain, and make the protection requirements with the following factors appropriately: l The building facade (including materials and colors); l The structural system and layout plans; l The interior decoration and architectural component with the characteristics at the time; l The landscape such as architectural pieces, virescence, fountain, sculptures and paving with the characteristics at the time; l The spatial pattern and overall style To learn successful cases.

Thereby, two of the key aspects in simulative analysis are the mechanical loads during the process [1, 2] and the developing chip form [1] when drilling with twist drills or indexable drills.
As material model the software implemented data for AISI 4140 steel is used while the workpiece is considered to behave pure plastically.
This might be due to thermal softening of the workpiece material and a temperature field that emerges ahead of the tool tip.
For future research it is necessary to obtain proper material data to achieve results which are in agreement with experimental results.
