Based on Universal Soil Loss Equation and the natural environment characteristics of Fujian Province,four natural factors affecting soil erosion were chosen as the assessment indices,which are the rainfall erosivity,relief,soil texture and vegetation types,and the soil erosion sensitivity of Fujian Province was assessed under the support of GIS.

根据通用土壤流失方程的基本原理，结合福建省的自然环境特征，选择降雨侵蚀力、地形起伏度、土壤质地、植被类型4个自然因子作为评价指标，在G IS软件支持下对福建省土壤侵蚀敏感性进行评价，评价结果综合反映了福建省土壤侵蚀敏感性的分布规律，为土壤侵蚀防治、生态环境保护与建设以及土地资源合理开发利用提供依据。

Finally, the grafting polymerization of textile materials initiated by microwave low temperature plasma was conducted. Knitted cotton fabric was grafted by AMPS first, then knitted cotton and terylene/cotton fabrics were grafted with AMPS/NIPA dualistic monomers respectively. By means of grafting polymerization, the P dualisticintelligent hydrogel was added to textile.The influences of the factors on add-on, such as treatment time and power of plasma, concentrations of crosslinking agent and total monomers, proportion of AMPS, polymerizing temperature and time etc, was studied fully. The optimal conditions of grafting polymerization initiated by microwave low temperature plasma were determined by orthogonal design, variance analysis and mathematical statistics method so as to analyze the main influencing factors. Then swelling/deswelling kinetics, temperature-sensitivity and pH-sensitivity of grafted textile were studied. The performance indexes of hydrostatic pressure, moisture permeability and bursting strength of the knitted cotton and terylene/cotton fabrics before and after grafting were compared and evaluated synthetically.

此后用微波低温等离子体引发纺织材料的接枝聚合反应，分别研究了棉针织物接枝AMPS和棉、涤棉混纺针织物接枝AMPS/NIPA二元单体，使智能凝胶以接枝的方式添加到纺织材料上；详细探讨了微波低温等离子体处理功率和时间、总单体浓度、AMPS单体浓度、交联剂浓度及聚合反应温度和时间等因素对增重率的影响，通过正交设计、方差分析及数理统计对各影响因子进行分析，确定了微波低温等离子体引发接枝聚合的最佳工艺条件；对接枝纺织材料的失水-吸水动力学、温度敏感性、pH敏感性等进行了研究；对接枝前后棉、涤棉混纺针织物的静水压、透湿性和顶破强力等服用性能指标进行了对比和综合评价。

According to the above study results, especially the steady operation of two-sludge system（2A/O+N 2SBR）, it can be proved that denitrification and excess phosphorus uptake are relatively independent and intersectant biological processes. The overlap is that denitrifying phosphorus removing bacteriawhich possesses the two bacterial metabolisms, could utilize nitrate as an electron acceptor for phosphorus uptake. The two-sludge system can not only combined biological phosphorus removal and denitrification processes to form a process in practical wastwater treatment , but also solved the main difficulties of current single-sludge systems:①the sludge age competition between phosphorus removing bacteria and nitrifier;② the substrate competition between denitrification and dephosphatation.

以上的研究结果，尤其是时间序列的双泥生物反硝化除磷脱氮系统工艺（2A/O+N 2SBR法）的稳定运行，不仅证明了生物脱氮与生物除磷是两个既相对独立又相互交叉的生理过程，其交叉点是同时拥有硝酸盐还原性和超量吸磷这两种生化特性的细菌进行的反硝化吸磷脱氮生化反应，而且双泥系统工艺克服了常规单泥生物脱氮除磷工艺的两大问题（①聚磷菌和硝化菌的SRT相互干扰；②反硝化与生物除磷竞争VFA），同时保证了脱氮和除磷效果，排水指标达到污水综合排水标准（GB8978-1996）的一级标准，具有实际工程使用价值。
