Kefeng A is an early maturing indica cytoplasmic male sterile （CMS） line of rice. Combinations derived from Kefeng A and late maturing indica restorer lines showed dominant earliness to various extents. To understand the genetic basis of dominant earliness, the genotype of photoperiod-sensitive genes in Kefeng A was analyzed using a complete set of heading time near isogenic lines （NILs） EgO to Eg7, ER, LR, T65, T65E^b, T65E^bm, T65m, NIL（Hd1） and NIL（Hd4）. Results indicated that Kefeng A contained two dominant photoperiod-sensitive alleles E1 and Se-1^U on E1 and Se-1 loci, respectively, and the genotype of photoperiod-sensitivity genes for heading time in Kefeng A was E1E1e2e2E3E3Se-1^USe-1UEf-1Ef-1. Based on the detected heading time genotype, in combination with the heading time of Kefeng A and the early maturing phenomenon in its derived F1 hybrids, it is speculated that Kefeng A might carry a dominant inhibitor gene Su-E7 for the dominant photoperiod- sensitive gene E1, and a recessive inhibitor gene i-Se-1 for another dominant photoperiod-sensitive gene Se-1. The reason why F1 hybrids from Kefeng A exhibited early maturing was hereby analyzed and the breeding value of dominant earliness related genes in Kefeng A was discussed.

[ Objective] The research aimed to study influence of different C/N ratios on aerobic denitdfication characteristics of the strain. [ Method] 5 aerobic denitdfying bacteria were isolated from activated sludge at low temperature and low C/N ratio, and their denitdfication capabilities were verified. Influence of different C/N ratios on denitdfication capability of the strain was determined. [ Result] In the five isolated aerobic denitdf- ying bacteria, except HFX08 was g-, HFX00, HFX01, HFX12 and HFX13 were g ＋. HFX08 belonged to Pseudomonas, and other strains be- longed to Acinetobacter. As C/N ratio increased, denitdfication velocity increased, and the highest removal rate of nitrogen for the five strains could reach over 92%. [ Conclusion] The research could provide reference for design and operation of the sewage treatment process with low C/N ratio in winter in the north.

采用简单遗传算法进行超分辨率图像恢复时,往往由于种群多样性的不足而导致早熟收敛,得到的图像恢复质量不理想。针对该问题,提出了一种基于灾变遗传算法求解高分辨率图像最优估计的方法。在简单遗传算法的基础上,该算法以适应值方差作为灾变的判断条件,将共轭梯度算法作为灾变算子重新构建种群,从而增加了种群多样性。同时对灾变条件和灾变规模进行了分析,并且给出了根据进化代数自适应调节灾变条件的方法。仿真实验表明了该算法的有效性。

大断面膨胀土隧道结构受力特性测试研究

研究目的:大断面隧道因其跨度大、形状偏于扁平,在施工过程中表现出独有的力学特点,经常造成围岩大变形侵限、区域性塌方、底鼓和支护结构开裂等施工风险,而这些特点在膨胀土环境中表现的尤为明显,因此研究大断面膨胀土隧道支护结构受... 详细信息

研究目的:大断面隧道因其跨度大、形状偏于扁平,在施工过程中表现出独有的力学特点,经常造成围岩大变形侵限、区域性塌方、底鼓和支护结构开裂等施工风险,而这些特点在膨胀土环境中表现的尤为明显,因此研究大断面膨胀土隧道支护结构受力特性具有重要的工程应用意义。本文以银西线庆阳隧道为工程背景,首先通过室内试验确定红黏土围岩的膨胀参数,然后利用现场监测手段对庆阳隧道支护结构的力学特性进行研究,并评价其支护结构受力性能,以期对同类隧道施工起到一定的指导作用。研究结论:(1)隧道膨胀土最大膨胀率为67%,最大膨胀力达到67.42 kP a,施工过程中应加强超前地质预报,尽可能减少水害对施工的影响;(2)隧道拱顶、两侧拱腰及底部具有较大围岩压力,围岩压力呈对称分布,初支闭合后拱顶附近围岩压力基本稳定,但两侧拱腰及仰拱位置围岩压力持续增大;初支闭合后钢拱架受力持续快速增长且受力基本对称,隧道上部初支内钢拱架受力始终较大,拱顶钢拱架应力最大达到1.46 MPa;(3)二衬施作后,初支仍存在一定变形,二衬左右两侧衬砌压力增长显著,二衬两侧拱脚位置混凝土应力增大明显;(4)本研究成果可为大断面膨胀性隧道设计优化和安全施工提供理论指导与科学依据。
