The visualization analysis of dispersion state of the filler m silicone rubber was based on the fluorescent labeling and the laser scanning confocal microscope. The fluorescent silica microspheres were modified by different silane coupling agents, and the contact angle analysis, thermogravimetnc analysis and fluorescence spectroscopy were used to describe its surface properties. Both hydrophobic effect and bound rubber content of modified fluorescent silica microspheres are KH-570>KH-560>KH-550. Visual analysis results show that the aver- age size of aggregates and network connectivity of KH-570 modified fluorescent silica microspheres were 2.61 ̡m and 47%, KH-560 modified it were 2.95 /im and 43% and KH-550 modified it were 3.32 f(m and 41 %. The visual analysis method of the modified fluorescent SiO2 microsphere is beneficial to observe the dispersion state of it m the silicone rubber, and this method can statistically analyze the particle size of the modified fluorescent SiO2 microsphere aggregates. This method is helpful to evaluate the dispersion state of the filler m the silicone rubber. [ABSTRACT FROM AUTHOR]

The filler network structure of the silica-reinforced silicone rubber was simulated by using the rare earth europium complex sensitized fluorescence enhancement technique. The filler network structure, curing performance and dynamic mechanical properties of the silica-reinforced silicone rubber were characterized by scanning electron microscopy, laser scanning confocal microscopy, rubber processing analyzer and solid rheological analyzer. The filler network connection rates of 30-60 parts of silica-filled silicone rubber were 31 %, 41 %, 58% and 70%, respectively, visualized by laser scanning confocal microscopy. The minimum torque (ML), characterization of filler-filler interaction, during the vulcanization process, the Payne effect and the shear storage modulus difference ΔG'(G'0--G'∞) in the strain sweep process were gradually increased. The results show that the filler network structure is gradually formed inside the silicone rubber with the increase of fillers, which is consistent with the obtained filler network connection rate, indicating that the combination of fluorescent labeling and laser scanning confocal microscopy can realize the visualization of the filler network structure in the silicone rubber.

[Purpose/Significance] The application of digital humanities and geographic information system can directly illustrate the geographical distribution characteristics of female writers in Ming and Qing dynasties, and provide quantitative references for the analysis of formation of such geographical distribution. [Method/Process] This paper analyzes the related information of female writers in Songjiang prefecture in the Ming Qing Women's Writings Database, including their dynasties, backgrounds, marital status, and works. Based on the geographical information system technologies, a visualization map for the geographical distribution of female writers in Songjiang prefecture during Ming and Qing dynasties is displayed. The correlation analysis is used to explore the influences of social economy and education on the geographical distribution of female writers from a spatial horizon. [Results/Conclusions] During Ming and Qing dynasties, there were 139 female writers in Songjiang prefecture. 77.7% of them were distributed in the central counties (such as Huating County, Lou County and Shanghai County), while 22.3% were distributed in other marginal counties. Additionally, the number of female writers in each county is significantly correlated with distinguished families and schools, but not with the farmland tax and the number of cotton industry towns in each county.
