By defining the concept of low carbon clothing and summarizing the design factors, this paper analyzes the low-carbon characteristics of pleated design in the processes of design, production and wearing. In the concept of low-carbon clothing, pleated design achieves the structure design of “multiple ways of wearing one piece of clothes” and “one-piece style”. It saves the cost of clothing, satisfies people’s diverse needs for clothing, brings a fresh wearing experience to customers, advocates the concept of “green” wearing and consumption, and meets people’s spiritual demand for low-carbon culture and life.

Through Mathematical derivation can be R(d) the parameters of the function expression R (s), but is generally must use computers that are to be evaluated specific iterations. According to R (d) definitions of functions, to seek the iterative algorithms for key is to first search for describes the mutual information of both a pair of independent variables. This selected, namely mutual information can be represented as . Through the simulation, study attained R(d) of the main properties of the function.

CPM as a typical constant envelope modulation, timing synchronization method of research is becoming increasingly important. Articles research associate of constant envelope modulated signal timing synchronization methods, respectively, measured from the errors of timing synchronization, synchronize the system's structure, partial adjustment aspects are discussed. Theoretical analysis on the basis of performance in different conditions, and verify its performance. Meanwhile, encode with sync cascade simulation testing, discusses the overall robustness of the algorithm.

Hydrothermal treatment method was proposed to prepare boehmite and the effect of precursors on the morphology of beohmite was investigated. On the coordinate effect of organic and inorganic flower-like AlOOH assembled by nano-plates can be obtained by Al(NO3)3 as precursor. 3D urchin-like AlOOH superstructures consisting of nanoribbons were produced from hydrate AlCl3 as reagents. Dissolution and recrystallinity of intermediate product AlOCl caused this result. Globe and hollow sphere morphologies of beohmite were synthesized by Al2(SO4)3 in a water-alcohol system. The formation mechanism is also because of the dissolution and recrystallinity of intermediate product sodium sulfate aluminum. Beohmite prepared by hydrothermal treatment was transformed to γ- Al2O3 at 600°C. The morphologies of γ- Al2O3 powders were still kept their original forms.

Using aluminum sulfate as precursor and urea as precipitator, hollow sphere boehmite was synthesized by hydrothermal treatment on 140°C for 24h. The time effect of as-synthesized product was studied by XRD, SEM and TG, et al. The results show that with the hydrothermal time increasing the product’s phase transformed from sodium sulfate aluminum to amorphous form to mixture phases of sodium sulfate aluminum and boehmite to boehmite. After 24h hydrothermal treatment, the product can completely change to boehmite. With the hydrothermal time increasing, the micromorphology of hydrolysis product experienced the evolution of smooth dense globe to core-shell sphere to hollow sphere.

Presently, there are a significant number of investigations that study the influences of the hydrogen embrittlement on pressure vessels for hydrogen storage. But few of them consider the effects of helium-3 decayed from hydrogen. This paper studies the effects of the high-pressure hydrogen on mechanical behavior of a kind of steel pressure vessel by elastic-plastic finite element simulations, based on the explosion tests data of 4-, 6-, 14- and 17-year hydrogen storage vessels and relating experimental data of materials properties. Then the mechanical responses of the 50-year hydrogen storage pressure vessel are predicted. The results provide guidelines for design and evaluating hydrogen storage vessels.

Information technology which takes the Internet as representative swifts development, more and more people who are pursuing more interesting and better tasting lifestyle pay more attention to the personality, emotion and originality of the product. Now, consumer market enters a new period which is characterized by fast, changing and personality. Under this complex background, how Designer organize production, sale and other clothing enterprise resources well, provide very markeTable design, is very important to promise the achievement of clothing enterprise, take full advantage of all the enterprise resources and adapt market changing. All these are to promise that a costume brand can possess core competitiveness. From the Influence of product, price, environment and publicity on a good clothing market design point of departure, preparation before design, process of design, evaluation of design, result and verification of design, these elements of design activity were analyzed in this paper. The results show that it is important for designer to cultivate the sensibility to the clothing market; to master the relation among design ,market and popular ,to guarantee design promote the sell, to achieve the goal that design can meet demand that people want to look for better lifestyle.
