Good thermal stability and self-extinguishing behavior was observed with the cured polybenzoxazine resins. Second, furan-containing benzoxazine monomers, P-FBz, BPA-FBz, and 4FP-FBz were prepared using furfurylamine as a raw material. Formation of furfurylamine Mannich bridge networks in the polymerizations of P-FBz and BPA-FBz increased the cross-linking densities and thermal stability of the resulting polybenzoxazines. P-FBz and BPA-FBz- based polymers also exhibited high glass transition temperatures above 300℃, high char yields, and low flammability with a limited oxygen index value of 31. The dielectric (Dk3.21–3.39) and mechanical properties (high storage modulus of 3.0–3.9 GPa and low coefficient of thermal expansion of 37.7– 45.4 ppm) of the P-FBz and BPA-FBz-based polymers were superior or comparable to other polybenzoxazines. 4FP-FBz used for polybenzo- xazine modification by means of formation of benzoxazine hybridation with P-FBz.

During the establishment of sediment yield dynamic model at the watershed outlet, it was difficult for us to carry out dynamic monitoring of each impact factors in the whole basin, because it was a long time research and was in very large-scale watershed. Taking into account the interannual variability of sediment yield mainly affected by hydrological conditions of rainfall - runoff and underlaying surface changes caused by soil conservation measures, a combined influence factor which is related to surface runoff modulus and the implementation time of the water and soil conservation project was proposed for the first time. Furthermore, its specific expression was determined through dimensional analysis and non-linear regression multianalysis.
