Hot coilbox bending rolls are important equipment for making coil in hot strip rolling line. Bending rolls include coiling speed control and rolls gap position control need position and speed synchronization. The methods of hot bending rolls control are discussed, then test in tangshan hot strip rolling line and obtain is satisfied effectly.
Switch cubicle has been widely used in switchgear substation and switchgear house. However, the switch cubic accidents are greater due to various causes. Further more, the single accident would damage other switch cubicles, because of its special assembling. Some accidents caused by insulation problem happened in our power supply company. And the corona happened inner the switch cubicle was found,...
The paper explores and analyzes the game expression problem of Chinese future product design under the background of the low-carbon economic development in current times of globalization. In low-carbon economy era, as the primary focus of consumers gradually shifts from material to spiritual, the concept of product design will shift from function to game. The paper explains the cultural functions...
Biochemical reaction network simulation is the core task in the new virtual cell simulation technology, because it carries out a lot of complex biochemical reactions. A new general algorithm is proposed to simulate the biochemical reactions in virtual cell using multi-agent. The algorithm is based on a deterministic algorithm for biochemical reactions in virtual cell. It overcomes the shortcoming...
An eigenvalue equation for the wave number of an electromagnetic wave propagating in a photonic crystal containing frequency dependent material is presented.
Two-photon fluorescence was used for the first time to measure sodium fluorescein distribution in live corneal tissue. The diffusion depth was determined to be 350 µm under study conditions with 11µm axial resolution.
A nano-scale metal-organic framework Eu(BDC)1.5(H2O)2 was synthesized in a reverse microemulsion system. Scanning electron micrographic (SEM) showed that they were nanorods with 100~200nm in length by 25nm in diameter. Sensing experiments were carried out to examine the potential of Eu(BDC)1.5(H2O)2 for sensing small molecules such as acetonitrinile and acetone. The luminescent intensity was largely...
Gardner's multiple intelligence theory provides a new thought for the colleges' cultivation of talents by its rich educational content. The multiple intelligence theory enlightens us that the intelligence structure of the creative talents is an integrated system where various intelligence essential factors are realigned, maintaining close ties with each other and make the mode of thinking diversified...
The product collaborative design process had such characters: multidisciplinary, hierarchy, concurrent, phase, iteration, cooperativity, restriction and conflict- ineluctability. The present product design process modeling methods have their own characters, however, most of them suppose design to be a simple technical decision-making activity. They fail to describe the information completely, support...
Informationization of teacher education program is the need of society, and also the objective requirement of school and subject construction. Application of information technology in teaching promotes information-based development of teacher education program. This paper takes integration of information technology and ecology teaching methodology program as an example, and probes into the channels...
This paper mainly analyzed the safety feasibility of liquid organic heat transfer material heater used in the production process of bleaching powder concentrate. Firstly, inherent hazards of bleaching powder concentrate are fire and explosion and it must not be stored or transported with oils and so on, and after analyzing the whole process flow the harmful factor is dry bleaching powder concentrate...
Design is the artistic creation activity conducted by human beings in order to accomplish certain purposes. Modern design has already taken on a diversified trend. Design becomes the tool to pursue fashion. The purpose of design is alienated, while the nature of design becomes vaguer and vaguer. With the intensification of interdisciplinary research of subjects, identification of the design subject...
To study the effect of Asparagus officinalis polysaccharide on the number and activity of erythrocyte complement receptor 1(CD35) in S180 mice. Red blood cells from mice venous blood are labeled by rat anti-mouse CD35 monoclonal antibody and FITC-conjugated goat anti-mouse antibody. Using flow cytometry, we determined the number of CR1. Using microscope, we studied the adherence between erythrocyte...
The modified nanometer-sized TiO2 as a solid sorbent was prepared by using impregnation method, and characterized by using SEM. The adsorption properties of the sorbent to Co(II) in static system, main factors affecting the adsorption and desorption, adsorption isotherms and influence of coexisting ions on the determination of Co(II) were investigated by FAAS, and regeneration experiments were carried...
Based on the demand of material, this paper first selected the evaluating factors about choosing suppliers, and analyzed the correlation among evaluating factors. Then, by combining the merits of Analytic Network Process (ANP) and entropy right, this paper proposed a method to calculate the compound rights of factors. The new method fully takes advantage of the relationship between factors and the...
With the rapidly changing, time limit has become one of the key factor for the project to the success. So the research about how to control and optimize the schedule of the project has been hot. We have applied the advanced control methods and optimization software to the project, but the proportion of the project delay is still high. According to survey, we find that the project delay is not caused...
In this paper, the material measure of BBD ball mill based on multi-information data fusion is researched. By combining the Rough Set and Radial Basis Function neural network, this method can not only solve the priori difficulty in obtaining information in data fusion and a large number of redundant data existing problems in system, but also greatly increase the approximation ability and learning...
The basic principle of embed-in-wall heat flux sensor as well as its structure and manufacturing are introduced in this paper. And the flux distribution of embed-in-wall heat flux sensor and its deviation are analyzed. The concept of isolation layer is proposed. The introduction of isolation layer has important significance to improve the measurement accuracy of heat flux sensor.
This study was aiming to investigate the fabrication and characterization of the porous chitosan/gelatin scaffold cross-linked with genipin (GP) which is widely used as a natural and non-toxic cross-linking agent. The chitosan/gelatin scaffold was prepared and cross-linked with 1% or 2%(w/w) genipin for 24 hours at 37degC, then pre-freezing for 48h at -20degC and -80degC before freeze drying. As a...
Biodegradable polymers have been widely used as scaffolding materials to regenerate new tissues. To mimic natural extracellular matrix architecture, a novel highly porous structure, which is a three-dimensional interconnected fibrous network with a fiber diameter ranging from 100 to 500 nm, has been created from poly (L-lactic acid) in this work. These fibrous matrices were prepared from the polymer...
