This study was based on the soy protein isolates as raw materials. Chemical modification( acetylation,succinylation ,phosphorylation and urea modification) of SPI were used to improve adhesive strength and water resistance of SPI-based plywood adhesives. Then two modified ways combined were applied to SPI and their adhesive properties were studied. This research also characterized the thermal and adhesive properties of two major soy protein components 7S conglycinin and 11S glycinin after urea modification. Finally, the mechanism of improving SPI's adhesive properties was preliminarily discussed.

The stable or unstable state of the montmorillonite-water dispersion is mainly effected by the properties of montmorillonite, water, and stabilizers as well as their interactions, while the type, the structure, the properties and the concentration of the stabilizer play dominate roles. Based on the molecular designing clues, this research selected three sulfonated copolymers as the stabilizers, i.e. the sodium 2-acrylamido-2-methyl-1propane sulfonate /acrylamide /disodium itaconate terpolymer, the AMPS/AM/N-vinyl pyrrolidone terpolymer and the sodium styrenesulfonate /IA copolymer. The preparation and characterization of the sulfonated copolymers were discussed, the high-temperature stability of the montmorillonitewater dispersion was characterized with the rheology, the filtration, the particle size distribution, the electrostatic properties, and the adorption of the sulfonated copolymers onto montmorillonite particles. At the same time, a systematic mechanism of the hightemperature stabilization of the dispersion was presented.

J. Gibson (Michotte 1963; Gibson 1986). Empirical studies deriving from the former involve the direct perception of the rich properties constitutive of causation. Those following on the latter concern the direct perception of humanly relevant functional properties of the environment (physical-geometric features may be given directly as hiding places or escape routes, for example), as well as intentional and mentalistic properties.

Shanghai Impregnant Factory located in the Park of World Expo 2010 Shanghai was set up 70 years ago and abandoned for 10 years. The quantities of soil microorganisms, soil enzyme activities, soil chemical properties and their relationships under Cinnamomum camphora community, Metasequoia lyptostroboides community, Nerium indicum community and Cinnamomum camphora+Ligustrum lucidum shrub community in the factory were studied. Results showed that the differences in soil properties were significant in upper soil layer (0~20 cm) and the vertical distribution rules of soil properties were different under four plant communities.
