NaCl胁迫下杂交稻农艺性状配合力及遗传力分析

采用4×4不完全双列杂交设计,在NaCl胁迫下对杂交水稻主要农艺性状进行了配合力和遗传力分析.结果表明,在调查的10个性状中有4个性状受NaCl胁迫影响差异较大,母本的千粒重及父本的粒厚一般配力差异显著,杂交组合的株高、粒厚、结实率及千粒重特殊配合力差异极显著,其中杂交组合N28S×中花14具有较高的配合力,受NaCl胁迫影响较低。株高及千粒重的广义遗传力和狭义遗传力均较高,可作为杂交水稻耐盐性的选育依据。

The influence of a non‐associated flow rule on the calculation of the factor of safety of soil slopes

This paper presents a method that incorporates a non‐associated flow rule into the limit analysis to investigate the influence of the dilatancy angle on the factor of safety for the slope stability analysis. The proposed method retain's the advantage of the upper bound method, which is simple and has no stress involvement in the calculation of the energy dissipation and the factor of safety.

The Dependence of Water Exchanges between the Kuroshio Water and Its Surroundings on the Characteristics of the Kuroshio‘s Meanders

Observation of fluid parcel pathways in the Kuroshio Stream revealed a striking crossstream pattern associated with the Kuroshio‘‘ s meanders. In order to understand the observed pattern, a two-dimensional kinematic model of a meandering jet was developed which could be used to examine the relationship between streamfunction patterns and fluid parcel trajectories. The experiments designed to investigate the dependence of the water exchanges between the Kuroshio water and its surroundings on the characteristics of the Kuroshio‘‘s meanders involved the downstream speed,phase speed and the amplitude of other propagating waves. The results suggested that fluid parcels could cross the meandering jet to and fro; and that the water exchanges between the Kuroshio and its surroundings increased with a) increasing meander amplitude, b) decreasing downstream speed, and c) increasing wave phase speed. The results also showed that when the meandering jet was disturbed by other propagating waves, more effective water exchanges could be induced.     

工厂化养殖暗纹东方鱼屯致病菌的分离和鉴定

从不同养殖场患病暗纹东方鱼屯(Takifaguobscurus)的鳃、肠、肝、肌肉及溃疡部位分离到9株菌株,经人工感染致病性试验,其T-22、T-11、J-2、H-3、H-5表现出较强的致病性,出现症状与自然发病鱼相同。通过对菌体形态特征、培养特性和API20E细菌生化快速鉴定试条的测定,分别鉴定为温和气单胞菌(Aeromonassobria)、豚鼠气单胞菌(Aeromonascaviae)、嗜水气单胞菌(Aeromonashydrophila)、类志贺邻单胞菌(Plesiomonasshigelloides)、霍乱弧菌(Vibriocholerae)。证实这5株菌为致病菌。药敏试验结果表明9种药物对温和气单胞菌、豚鼠气单胞菌、霍乱弧菌均有较好的抑菌效果;嗜水气单胞菌表现出明显的耐药性。氟嗪酸、环丙沙星、复合磺胺对类志贺邻单胞菌有一定抑菌效果。

对松辽盆地钱家店凹陷铀成矿作用的重新认认识

钱家店凹陷中的含矿层位主要为上白垩统姚家组,前人认为其中的红色砂岩为原生成因,但大量的证据证实砂岩原生应以灰色为主,红色砂岩为后生氧化蚀变造成,并控制着钱家店铀矿床铀矿化的产出.在此基础上建立该矿床的后生蚀变分带,依次为红色蚀变带、黄色蚀变带、灰白色蚀变带、过渡带、原生带,红色蚀变带为主要的氧化带,铀矿化主要集中在过渡带.平面上铀矿化主要分布于层间氧化带前锋线附近的位置,并在氧化舌状体的前端和两个氧化舌状体之间存在铀的富集.文章最后还建立了该矿床的成矿模式,并对区域上层间氧化带的展布进行了讨论.     

Development of a 3D GIS and its application to karst areas

There is a growing interest in modeling and analyzing karst phenomena in three dimensions. This paper integrates geology, groundwater hydrology, geographic information system (GIS), database management system (DBMS), visualization and data mining to study karst features in Huaibei, China. The 3D geo-objects retrieved from the karst area are analyzed and mapped into different abstract levels. The spatial relationships among the objects are constructed by a dual-linker. The shapes of the 3D objects and the topological models with attributes are stored and maintained in the DBMS. Spatial analysis was then used to integrate the data in the DBMS and the 3D model to form a virtual reality (VR) to provide analytical functions such as distribution analysis, correlation query, and probability assessment. The research successfully implements 3D modeling and analyses in the karst area, and meanwhile provides an efficient tool for government policy-makers to set out restrictions on water resource development in the area.
