Abstract: The fashion show was needed to inosculate clothing, music, dance, music, drama, art, sculpture and other arts as a whole,and conduct comprehensive art creation.The stage art design was a very important part in the fashion show, the artistic atmosphere of the show theme need to express can be rendered and created. The expression of fashion show on the clothing art beauty, dynamic beauty and static models walk the other beauty can be better presents,and more vitality. The overall effect on the fashion show has a crucial role.Therefore, this paper,the special elements of stage art design was analysesed,and the concrete application of the stage art design in the fashion show was explored.

Abstract: For seamless fashion via the jacquard weaving, three dimensional forms for silhouettes of garments are critical research areas. Basic principles of three-dimensional weaving originate from manufacturing of apparel. Darts, tucks, and gathers are common approaches to changes of sectional areas.3D forms are usually achieved by cutting and sewing darts or pleats. In this paper, three-dimensional forms of one layer elastic fabric is to process a mono-layer fabric into some three-dimensional forms via the relative decrease and increase of partial areas on a piece of jacquard woven textile. This paper reports the basic principle and theoretical model for 3D form predicting. The experimental samples via jacquard basically coincided with the theoretical estimates.

Abstract: This article starts from discussing the quality and security issues of children’s textiles inrecent years, then it analyzes the current application range of children’s textiles in their space environment, the development status of children’s green textiles and the application of children’s space environment. From the status quo and the perspective of domestic and abroad ecological standard of green textiles, the article emphasizes on the importance of green textiles application in children’s space environment designs. It also points out that green textiles will become the development direction of children’s textiles. Finally, it offers according strategies and suggestions.

Abstract: The fiber characteristics directly affecting the yarn tensile properties are analyzed and the features of GA-BP artificial neural network are presented. Based on the interrelationship among the fiber characteristics, which could led to a worse predicting result, Principal component analysis (PCA) is adopted to solve this problem. 12 characteristics of cotton fiber tested by HVI or AFIS and yarn process parameters, such as combing, degree of twist, yarn count, was preprocessed by this method and 10 independent comprehensive indexes are induced and substituted into GA-BP artificial neural network as input factors. For further comparison, the 10 dimension reduced indexes and the 15 initial variables are respectively introduced into the GA-BP and BP artificial neural network to develop 4 prediction models. By comparing the accuracy in predicting yarn tenacity, it is concluded that GA-BP model has higher accuracy than BP model, and the dimension reduced indexes based on PCA would decrease the accuracy in prediction instead. So, blindly using PCA method for reducing the complex correlation among input variables was not helpful for the prediction accuracy.

Abstract: Geometric structures of Fe_6-xSi_x(x=1-5) clusters have been systematically studied at the BPW91 level by density-functional theory (DFT). Calculated results show that the Fe atoms of the lowest-energy structures of Fe_6-xSi_x clusters tend to go together, and Si atoms tend to occupy surface site bonding with iron atoms as many as possible. Further, we analyze the stability of the lowest-energy structures of Fe_6-xSi_x clusters, and the corresponding results of the HOMO, LUMO as well as the HOMO-LUMO energy gap show that the Fe₅Si and Fe₄Si₂ clusters have special stability.

Abstract: Heavy metal pollution has raised a lot of concerns because of its bioaccumulation and non-degradability. A variety of methods have been applied in removal of heavy metals. This paper focused on the method of biosorption using biopolymer-based adsorbents in removing heavy metals from waster water. Cellulose and chitin/chitosan are abundant in supply and contain reactive functional groups. Cellulose-based adsorbents prepared from direct chemical modification or graft copolymerization are proved to show chelating ability to bind heavy metals. Chitin-and chitosan-based adsorbents have improved mechanical strength and better resistance to chemical conditions after physical or chemical modification. The regeneration and reusability of biopolymer-based adsorbents were also discussed in this paper.

Abstract: Hydrogenated amorphous carbon (a-C:H) films were prepared by microwave plasma chemical vapor deposition (MW-PCVD) technique with a mixture of acetylene and hydrogen. The morphology of three-phase a-C:H films, such as graphite-like, diamond-like and polymer-like were modulated by microwave power, deposition pressure, and flow ratios. Meanwhile, annealing does not seem to change the surface morphology or the film structure. The phase transitions are not found during the different annealing temperatures, showing that a-C:H films have a good thermal stability.

Abstract: Flame method is a new and simple method which may has the possibility of large-scale mass production for the synthesis of carbon nanotubes. It needs not the vacuum environment and carbon nanotubes can be captured at the normal atmospheric pressure. Synthesis of carbon nanotubes from the controllable flame is a new method. It can effectively avoid the defect of the traditional flame method. Experimental apparatus is mainly including controllable flame burner with its ancillary equipment, measuring instrument and catalyst preparation system, etc. The process of formation and growth for carbon nanotube is very complicated on account of the complexity of combustion and chemical reaction. It can be supposed that the formation and growth of carbon nanotubes from the controllable flame involves two steps in general.

Abstract: This paper presents a new method to fabricate the porous nanofibrous mats by dual-nozzle electrospinning. Poly (vinyl alcohol) (PVA) and Poly (vinyl pyrrolidone) (PVP) were electrospun from two different syringes and mixed on the rotating drum to form PVA/PVP composite nanofibrous mats. SEM morphology indicated that the amount of collecting nanofibers reduced with decreasing the ratio of feeding rate between PVA and PVP. After dissolving in alcohol, the pore size of nanofibrous mats with feeding ratio of PVA/PVP at 4/1 was 1.352μm, which would be more beneficial for cells to migrate from pores.

Abstract: The Polyacrylamide (PAM) is a frequently used flocculant for high concentration suspensions removal in water treatment characterized by the generation of large and dense flocs. In this paper, by using the anionic PAM as flocculant, a full-scale experimental study was carried out on flocculating ferric flocs sludge with pelleting flocculation blanket process under scale of 19~38 m³/h. The investigation aimed to optimum the dosage of the PAM and evaluate the application of the PAM in ferric flocs sludge treatment. The experimental results indicated that the increasing of PAM dosage could improve both outlet turbidity and thicken sludge concentration obviously, under the raw wastes concentration of 285~1022 mg/L, the system could achieve ideal operation effect with PAM dosage of 0.3~2.7 mg/L and treatment unit surface loading of 19~38 m³/m²·H. The investigation results also proved that there exists an approximately linear relationship between optimal PAM dosage and raw sludge concentration, that is, the increasing of raw sludge concentration would require synchronously rising of the optimal dosage. While the relationship between maximum surface loading and raw sludge concentration appeared negatively linear dependence, the maximum surface loading would decreased linearly with the increasing of inlet sludge concentration.
