A large number of domestic and international literatures have studied the pavement performance of composite modification of Buton rock asphalt and different asphalt modifiers. It is found that basalt blending can greatly improve the performance in an all-round way, in which high-temperature stability and low-temperature cracking resistance have superimposed effect. Waste rubber powder blending has little overall performance improvement. With diatomite blending the performance can exceed SBS modified asphalt. The research on composite modification of Buton rock asphalt still needs further study.

This article traces the essence of the tourist souvenir design, explaining the core of its value, the essence of local culture, and emphasizing the law of souvenir market value that maintains the uniqueness of local culture to attract purchases. By analysing the current situation of design homogeneity and lack of innovation in Chinese market, it proposes an innovative idea, “Back to Design Origins”. Then taking Nanjing souvenir design as an example, it introduces two innovative approaches, “Discovery and Application of New Cultural Elements” and “ Cute Stylization of Traditional Symbols”. In the end, it summarizes several feasible rules on element selection, symbolic method application, and carrier selection, mainly based on the thought of “Back to Design Origins”.

In order to study the influences of the contents of short fiber on the mechanical properties of concrete matrix, the properties of compressive, flexure and splitting of concrete matrix reinforced by alkali resistant glass fiber and calcium carbonate whisker were tested. To study the reinforced effect of different scale fibers on the flexure behavior of fine concrete sheets, the flexural tests of concrete sheet of fine concrete reinforced with basalt fiber mesh and short fiber composites were carried out. The results show that the properties of the compressive, flexure and splitting of fine concrete reinforced with appropriate amount of alkali resistant glass fiber and carbonate whisker are improved compared with that of concrete reinforced by one type of fiber. The flexure properties of the concrete sheets are improved obviously when continuous fiber textile and short fiber composite are adopted to reinforce.

As a widely used reinforcement method in tunnel engineering, the accuracy of models in numerical analysis has a vital influence on the reliability of the analysis results. To solve the problem of hard modeling for complicated models, this paper proposes to build models of different characteristics automatically by the means of Enterprise Knowledge Language (EKL) of CATIA, combining knowledge engineering template with parameterization. Furthermore, the stability of surrounding rocks and the distribution features of plastic areas were studied in different cases by CATIA-ABAQUS model. Besides, the effects and contributions of several parameters, including the rock-bolt diameter and interval between rock-bolts have been studied. It was found that: (1) Rock-bolt has a notable effect on the stability of the surrounding rocks. Increasing the diameter of rock-bolts contributes to significantly reduce the plastic area and the vertical displacement. With the increase of the quantity and the diameter of anchors, the degree of influence gradually weakens, showing the logarithmic relationship; (2) When the quantity and diameter of rock-bolts are constant, in the case in which the intervals between rock-bolts are various, the plastic area of surrounding rocks and the axial stress of rock-bolts are larger than that of the same distance, while the vertical displacement are uniform. (3) The excavation process has a great influence on the axial stress of rock-bolts and the redistribution of stresses in the surrounding rock.

Constructed wetland (CW) is a low cost and easy operation process for wastewater treatment, while filler clogging is one of the disadvantages for this technology. Using activated carbon as the filler, a regular CW and an integration of constructed wetland with microbial fuel cell (CW-MFC) were constructed. After continuous operation of four months, specific surface area and pore size distribution of the activated carbon were analyzed. The specific surface area of the fresh activated carbon was 133.8 m2/g, while the filler in the CW and CW-MFC systems had specific surface area of 38.1 m2/g and 58.2 m2/g. The surface decrease of the CW-MFC filler was 21% lower than that of CW filler. Comparing with the regular CW, the filler in the CW-MFC was more clogging resistant. The alleviation of the filler clogging in CW-MFC may be caused by the micro-electric field as the function of MFC. CW-MFC is a promising microbial electrochemical technology for wastewater treatment and filler clogging resistant, there are some detailed issues deserve to be further researched.

This paper expounds the background and market demands of the application of Form Bionic Design (FBD) in design innovation. Then it analyses the advantages of FBD and existing misunderstandings on its definition and application, leading to the topic on how to correctly understand the classification of Bionic Design. Also it clarifies the significance of the integration of Bionic Design, proposing that FBD should follow the requirements of users and Design Hardpoints (DHPs). Then through a series of design cases it introduces the application of FBD compromised with several special methods, which includes Userexperiencing in simulation, Modular Design for system optimization and Keywords on style positioning. Meanwhile it respectively discusses the purpose, the function and particular application of each method, providing practical reference for its particular combination with FBD.

The serious salinization of farmland soil and the shortage of water resources in arid areas are becoming more and more serious; In order to solve the problem of shortage of fresh water resources, find a resource that can be converted into fresh water; Brackish water is derived from farmland saline alkali land. Brackish water desalination technology has increased interest in scientists' research. However, brackish water can be used as an effective substitute for freshwater conversion because of its low salt concentration and can also be widely used in many water deficient countries. However, partial or total desalting of brackish water is essential to meet the water quality requirements of production and life. The selection of appropriate water resources desalination technology needs to understand the operation methods and technical means of the existing brackish water desalination process. Proper combination of desalination technologies can improve the efficiency of brackish water desalination. This review provides the latest advances in data, materials and categories that can help select and design requirements for specific applications.
