对水体污染物的无害化处理以及废水的资源化利用是解决水污染和缓解水资源短缺的重要手段,生物催化膜通过结合膜分离和酶催化可实现水体污染物的高效处理,开发高通量、高污染物去除效果的生物催化膜具有十分重要的意义。本研究通过压力辅助自组装,制备了不同材料和结构的疏松漆酶生物催化膜,以期获得高通量、高污染物去除效果,实现微污染物的有效去除和染料脱盐。从以下三个方面开展研究。（1）通过压力辅助自组装的方式将氧化石墨烯（GO）、聚乙烯亚胺（PEI）、漆酶（Lac）的混合溶液负载到水解聚丙烯腈（HPAN）基膜表面,成功制备了GO-PEI-Lac（7.5）疏松漆酶生物催化膜。探究了漆酶添加量对膜结构和性能的影响。当漆酶添加量为7.5 mg（0.27 mg/cm）时,膜的纯水渗透通量为207.3 LMH/bar,双酚A（BPA）去除率为95.3%,同时对多种染料的去除率达到97%以上,对4种常见盐离子的去除率均低于23%,显示出较高的盐离子渗透效果。对于多种酚类微污染物有较好的去除效果,同时还表现出较宽的p H适应范围。在经过10天的储存后仍保留86.1%的初始活性,6个循环后依然有80%以上的BPA去除率。（2）将UiO-66-NH（U6N）、壳聚糖（CS）和漆酶共混,利用戊二醛（GA）交联,通过压力辅助自组装负载到HPAN膜上制备以UiO-66-NH为主体的疏松漆酶生物催化膜,同时漆酶被共价固定到膜上。优化了U6N/CS的比例以及漆酶的添加量,成功制备了U6N/CS（5）-Lac（10）疏松漆酶生物催化膜,该膜的纯水渗透通量为121.8 LMH/bar,对BPA的去除率为94.0%,对于6种不同的染料均有96%以上的去除率,4种盐溶液则表现均低于28%以下的去除率,同时在不同微污染物、料液p H和料液浓度下均有较好的处理效果,在10天的储存后仍具有90%以上的初始活性,9次循环使用后BPA去除率依然保持在75%以上。（3）在涂覆一层聚多巴胺（PDA）的HPAN基膜表面原位生长磺化共价有机框架（SCOF）,进而通过压力辅助自组装将UiO-66-NH和漆酶固定到膜表面,成功制备SCOF/U6N（1）-Lac（10）疏松漆酶生物催化膜。漆酶与UiO-66-NH之间的静电相互作用使漆酶能够稳定负载在膜内。通过优化UiO-66-NH和漆酶的添加量调节膜的结构,在UiO-66-NH和漆酶的添加量分别为1 mg（0.036 mg/cm）和10 mg（0.37mg/cm）条件下,其纯水渗透通量为211.3 LMH/bar,BPA去除率为96.9%。对于刚果红（CR）、亚甲基蓝（MEB）、孔雀石绿（BG4）、铬黑T（CBT）四种染料的去除率达到98%以上,同时对于NaSO、Mg Cl和Na Cl的去除率为12.8%、11.5%和8.9%实现高盐渗透性。同时有良好的p H适用范围以及BPA浓度适用范围。在储存10天后仍保留90%以上的初始活性,在7次重用后仍有66.6%的BPA去除率。

Yihui1577 was bred after over 10 generations by crossing RI6 and Yunnan purple rice. Many new hybrid rice varieties had been bred with Yihui 1577, of which Gangyou 1577, Ⅱ you1577, Nyou 1577 and Yixiang1577 were certified by Sichuan Province Crop Variety Release Committee, Gangyou1577 and Yixiang1577 were certified by National Crop Variety Release Committee. The series varieties bred with Yihui1577 had been used widely with accumulated areas of 1 200 000 hm2. By using Yihui1577 as breeding material, an excellent restore line Yihui 3003 and some other restore lines, such as Yihui 1979, Yihui 315 with good rice quality and good combination ability had been bred. Analysis of combination ability and stability about restore line Yihui 1577 was made by using agricultural experimentation and statistical approach. The combination ability analysis was made in complete dual crossing method with 4 CMS lines and 6 restorer lines. It showed that the general combination ability effect value of Yihui1577 was 0.226, while Minghui63 was -0.113. So the general combination ability ofYihui1577 was prior to that of Minghui 63. Stability analysis showed that the F value of Gangyou1577 was 1.81378, while Sanyou 63 was 1.40327, both didn＇t reach significant level. So Gangyou1577 had the same stability as Sanyou 63. The same conclusion had got in the stability analysis of the breeds of Ⅱ you 1577, Yixiang 1577, Nyou 1577 and so on.

Using hybrid rice Yixiang1577 as the material, the mid-season and ratooning hybrid rice yield variation was studied in Southem Sichuan at different levels of nitrogen fertilizer. The results showed that rice yield by using N fertilizer increased to the most significant level than no fertilizer ones, and the mid-season rice and rice yield by using more N fertilizer increased to the significant level than less fertilizer ones. The rice yield by using no fertilizer ones increased to the most significant level than some used fertilizer, and the ratooning rice and rice yield by using more N fertilizer decreased to the most significant level than less fertilizer ones. The rice yield by using some fertilizer increased to the most significant level than no fertilizer ones for mid-season＋rationing rice and rice yield by using some fertilizer had no obvious differences at different nitrogen levels. Therefore, application of fertilizer can improve yield of mid-season rice and mid-season＋rationing rice. Soil test results showed that nutrient contents in rice field in South Sichuan were very rich in nitrogen, which could provide more adequate crop growth potential soil nitrogen nutrition. The crops with a deep root system had stronger ability of utilization on soil nitrogen. Therefore, the ratooning rice used no or little N fertilizer had a high yield performance because they made full use of soil nitrogen with deep root system.

多数智能服务机器人处于敞开式环境中,在复杂部署工作环境中障碍物的位置及形状均具有较强的随机性,导致机器人为完成避障出现路径重复、收敛速度偏慢的问题。为此,提出融合嵌入式视觉与激光测距的机器人自主避障方法。构建激光测距和嵌入式视觉传感器模型,利用尺度不变特征变换算法,提取并融合数据特征;当机器人感知到前方有障碍物时,首先考虑左侧通行,若机器人位置靠右,则根据最优路径选择右侧通行;基于通行规则设定合适的转向角度,保证机器人成功躲避障碍物。实验测试结果证明,所提方法可精准感知机器人周围环境中的障碍物,且避障路径合理,收敛速度更快。

针对超大规模卫星星座可能出现的运行维护成本高、任务可用度低的问题,结合卫星批量化生产以及采用一枚火箭将多颗卫星送入轨道(一箭多星)的现状,基于可维修备件多级保障库存技术(multi-echelon technique for recoverable item control,METRIC)提出一种超大规模卫星星座多级备份策略。首先,阐述了基于METRIC理论的卫星星座多级备份策略模型的原理,备份策略同时考虑地面备份、停泊轨道备份以及星座轨道备份3种备份模式,建立了考虑卫星年平均需求量、期望需求量与期望短缺数的星座可用度模型,包含制造费用和发射费用的星座备份费用模型,以及以星座可用度为约束,星座备份费用为优化目标的数学优化模型。然后,以某型超大规模低轨卫星星座为案例研究对象,使用遗传算法和边际分析法进行求解。最后,讨论了遗传算法与边际分析法在求解该优化问题时的优缺点。结果表明,在同一星座可用度指标下,采用星座多级备份策略可比采用传统两级备份策略有效降低每年备份费用;在保证星座可用度的前提下大幅降低了超大规模卫星星座的备份费用,可为精确配置各级备份卫星数量提供参考。
