Abstract
Poly(n-butyl methacrylate)(PBMA) has been prepared by a suspension polymerization process, and blended with polyacrylonitrile (PAN) in N,N-dimethyl acetamide (DMAc). The rheological analysis results show that the PBMA/PAN blend solution is a typical shear thinning fluid regardless of the PBMA content, and suitable for preparing fibers through a wet spinning process. Moreover, it is observed that with an increased PBMA content, the tensile strength of the blended fibers first slightly increases and then decreases, while the breaking elongation increases, which shows a higher value than that of the PAN fiber. The scanning electron microscope (SEM) and thermogravimetric analysis (TGA) results show that with low content PBMA that is evenly dispersed in the PAN matrix, the heat stability of the blended fibers is remarkably enhanced. The adsorption experiment results show that the addition of PBMA contributes to enhancing the adsorptive capacity of the blended fibers, and the adsorption of the organic solvents on the PBMA/PAN(30-70) blended fibers is two or three times higher than that of the PAN fiber

Abstract
In order to find a way to create the artistic conception of modern landscape space, the spatial analysis of Daguanyuan is carried out from the perspective of literature in order to find out the method of creating the artistic conception of modern landscape space. Adopting the method of general to special, from theory to practice, the argument with special significance is analyzed from the most common phenomena, and this argument is applied to the method of practical cases. The results show that Daguanyuan space in literature needs the audience's ability to understand words, the perception of space in film and television needs the audience's strong memory and imaginative thinking, while the perception of Daguanyuan space in garden art needs only basic discrimination ability. After analyzing the effect of Daguanyuan space construction from the literary perspective, it is believed that the writing techniques of starting point - development - climax - ending, wanting to carry forward first and restraining first, and reserving foreshadows in literature can be used for reference in modern landscape design.
