Abstract: Cellulose dissolution is one of the core issue of the process of the waste cellulose recycling. This paper study the dissolution process of the waste cotton textiles in the solution of ZnCl2 and LiBr, found that the ZnCl2 solution is more suitable for the cellulose dissolution, it is a very important significance for the recycling of cellulose in salt dissolution system.

Abstract: Kapok fiber has many excellent Performances. the surface and cross section of the kapok fiber were observed. These performances of the distribution of length and fineness, moisture regain, acid and alkali properties, and dyeing property were tested and compared for the kapok fiber, colored cotton fiber and white cotton fiber. The fabrics of same weave structure paramater were developed and the warmth retention property wewe tested. The results show that the surface of the kapok fiber is smooth，Cross section of the kapok fiber is round with hollow-structure. The length and fineness of the kapok fiber was lower than white cotton fiber and colored cotton fiber. The hygroscopicity and moisture guide properties of the kapok fiber was better than white cotton fiber and colored cotton fiber, the dyeing property of the kapok fiber was worse than white cotton fiber, the kapok fiber is alkali-resistance and non acid-resistant. The fabrics of the kapok fiber has better warmth retention property.

Abstract: Regenerated cellulose fiber is the most widely-used and most variety of cellulose fiber. Five categories and ten kinds of fibers such as lyocell fiber, viscose fiber, modal fiber, bamboo pulp fiber, and sheng-bast fiber were chosen as the research object. The sectional shape, crystallinity and degree of polymerization of fibers were tested and analysis, to explore the nature of the reasons for the formation of fiber performance difference, and to verify through experiments.

Abstract: The mechanical properties difference between soy protein isolate-based film and whey protein-based film was researched. The elongation at break, tensile strength of the pure soy protein isolate film both are better than that of the pure whey protein concentrate film, which is respectively 10 times and 25 times. After compounding the property of the whey protein concentrate film ameliorates. The elongation at break, tensile strength of the whey protein concentrate film increases respectively by 9 times and 16 times after the glutin is mixed. The elongation at break, tensile strength of the whey protein concentrate film increases by 1.1 times and 12 times after the chitosan is added.

Abstract: the Chinese traditional and auspicious cultures are primarily displayed in the form of figures, which have become a significant part of the Chinese traditional decorating arts as well as the excellent heritage of the national cultures. The traditional figures of Shanxi province owe their profound meanings and unique expressive force of art. This essay commits explanation in the perspective of the occurrence of the ecological idea, the category of the figures as well as the characteristics of their symbols. Multiple kinds of connection, support and interaction have made the figures of Shanxi form a kind of optimal ecological protection theory with the features of unique complementation and commensalisms.

Abstract: Soil samples with the green space soil in Qinhuangdao city were collected, and soil bulk density, pH,EC,organic matter,alkali-hydrolysable nitrogen,available phosphorus,available potassium were studied,and Nemero comprehensive index method was used to evaluate the soil fertility.The results indicated that the green space soil synthesis level was general.

Abstract: Environment protection is one of the core tasks of the higher colleges. Under the condition of the unchanged capital investment, how to make the capital efficiency of the environment protection maximized still has no mathematical models for references at the present time. In this article, by using the views of the system theory and the related methods of mathematics and statistics and combing the empirical data of the higher college construction

Abstract: The "Nature-human Integration" concept is the important part composed in China’s traditional culture, also is the simple world outlook and methodology. It has taken the huge and profound influence to the formation of Chinese civilization, and is the source to generate ideas for artistic designing. From the historical background of the " Nature-human Integration " concept, this paper expounds based on its artistic representations in nature, emotion, tolerance and view, and deeply elaborates on its instructive significance and positive effects in the development of modern artistic designing, pointing out that the essence of the "Nature-human Integration" concept is the lasting care to human and it stresses human must be harmonious with the natural environments: all things can be perpetuate only by endless circulation; accommodating and absorbing diverse cultures can bring permanent prosperity and luxuriance.

Abstract: By combining the current situation that China is seriously in shortage of the resources and has a very severe environmental pollution problem, the author carries out a study on the economic value of the recycled concrete, and then makes a qualitative and quantitative analysis on the economic feasibility of the recycled concrete. The analysis shows that the recycled concrete can save the aggregate resources and also can prevent the environmental pollution which is caused by the stacks of the waste concrete, and is a kind of green concrete featuring the sustainable development. Also, it is found that the economic feasibility of the recycled concrete can be embodied in the resource price, the urban garbage processing fees, and the governmental finance and taxation supports, etc. Therefore, it has been known that the production of the recycled aggregate is profitable and also is with a huge ecological benefit as well as a certain economic benefit.

Abstract: according to the present situation, the necessity and urgency of building and enlarging " vocational education city" is elaborated. Vocational l education brand of Chongqing has set up with the harmonious development of Chongqing. Environmental impact of Chongqing to build the western biggest "vocational education city" is also studied.
