Abstract: In this paper, three disperse dyes were selected to study the kinetic dyeing model of PLA fabric. Based on the dyeing results and the SEM spectrum of PLA fabric before/after dyeing, the kinetic dyeing model was established. Besides, the half-dyeing time and the diffusion coefficient of the disperse dyeing process were also tested. These research results will be very helpful to the development of the application of PLA fabric and also set a theoretical base for the dyeing of such environmentally friendly fabric.

Abstract: Low permeability fractured reservoir is a special reservoir with complex fracture distribution and dense matrix. Low permeability fractured reservoir always have small porosity, low pore pressure and permeability. Therefore, low permeability fractured reservoir has low oil recovery efficiency. Besides, the developing complex process and higher costs lead to lower economic benefit. Low permeability fractured reservoir production mechanisms in the fracture system mainly by the capillary force of water into the matrix. Therefore, the hydrophilic blocks of dense, self-priming effect of capillary water is the main mechanism of oil. In this study, numerical simulation, the establishment of a dual media model analysis showed that the capillary suction from the oil production rate and the final volume flow channel structure, the capillary force, viscosity of crude oil and other factors.

Abstract: Due to the requirement of lightweight in the automotive body structure design, the application of advanced high strength steel (AHSS) has been widely adopted in the automotive industry. However, the technical difficulties are also experienced in the forming process of stamping the advanced high strength steel. One of the major defects is springback. In this study, both the experimental approach and the finite element analysis were adopted to examine the springback phenomenon occurred in the stamping of a front bumper inner made of 590Y advanced high strength steel. The die compensation approach was employed to adjust the amount of springback to make the dimension of the automotive part conforming to the design specification. The accurate dimension of the production part validates the finite element analysis and the die compensation approach adopted in the present study provides a useful guideline for improving the springback defect in the stamping of advanced high strength steel sheets.

Abstract: nfluences of install and design of residential lighting on physical and mental health of residents in Dalain were studied by field investigation and questionnaire survey. Luminance simulation of the local light environment was analyzed by SM light environment test software. The results reflected that path luminance and entrance luminance are weak. There is a larger illumination gap between inside and outside of the district owing to bright commercial light. Part of landscape lights has a potential light pollution on the city ecosystem. Therefore scientific design and evaluation of light environment have a important influence on city life and traffic in the night.

Abstract: The city is a complex system. The construction of sports facilities is a subsystem of the city construction and the correct selection and construction is beneficial to promote the development of the city. It has become an important impetus for the development of city and will serve to undermine and hinder. On the other hand, stadium management and use depends on the surrounding environment support, venues and located in the region to other functional units coordination, organic intergrowth, will facilitate the system overall efficiency of each subsystem and the sustainable development.

Abstract: With the progress of science and technology, rapid development of city economy, city media facade become increasingly popular art form, its strong visual effect has great influence on city development.

Abstract: A systemically study on the new space structure steel - concrete composite ribbed shell is made, which is loaded by stepped load. The ultimate bearing capacity and failure modes are investigated based on the characteristic response indicators. In the foundation of large number of parameters analysis, the influence of the span ratio, span, boundary conditions and initial imperfection on the ultimate bearing capacity and instable dynamic failure are discussed in details. All the results will provide mass of data to the investigation of failure mechanism and the property under complex dynamical loads.

Abstract: Steel-concrete composite ribbed shell is a kind of shell structure based on the thin concrete shell, which has the advantages of two different materials, at the same time with steel nets shell and thin concrete shell structure. In this paper, the seismic performance of steel concrete composite ribbed shell is analyzed, in which the elastoplastic time-history analysis method is used to analyze internal force and deformation. Furthermore a parameter analysis is made to discuss the seismic performance, which considering different high-span ratio, section dimension, boundary conditions and structure division frequency. The influence on structure seismic performance and some structure dynamic response characteristics are obtained, which can be resulted for structural seismic design and referenced in steel-concrete thin shell design specification modification.

Abstract: DongYue Temple is an important part of Jin Memorial Temple, which has immeasurable cultural value. It is the indispensable supplement of various architecture artistic forms in Jin Memorial Temple. From the angle of the description of the hall buildings and murals, this article analyses the historical value, scientific value and aesthetic archaeological value of DongYue Temple.And fully reflects the Jin Memorial Temple is a rare ancient architectural complex, with the diversity of historical and cultural characteristics.

Abstract: Materials in sports building space plays not only a supporting role but also an important part of building exhibition. With the rise of intelligent and ecological buildings, as a building enclosure material properties and role will become more prominent. New advances in technology make material has been not just enclosure system, but with the external environment for building dialogue interface, visual, structure and control technique of bonding layer. How effectively function technology element integration in material artistic expressive force is the important thing in current material design.
