枯草芽孢杆菌B—916防治水稻纹枯病的田间试验

１９９２～１９９４年在田间小区试验比较两个拮抗细菌（Ｂ－９１６、Ｐ－９１）和井岗霉素对水稻纹枯病的防治效果。１９９４～１９９５年在江苏省３个基点上进行了Ｂ－９１６防治纹枯病的大面积示范试验。Ｂ－９１６发酵液在田间对水稻纹枯病的为害有较强的控制能力，发酵含菌量为２．５４×１０１１～２．５４×１０１２ｃｆｕ／ｍＬ时，用量３．７５Ｌ／ｈｍ２的防治效果为５０．０％～８１．０％。     

四季蜜龙眼产期调节技术应用效果调查

2014年3月至11月对广西桂平市金田镇古东村四季蜜龙眼生产基地产期调节技术应用效果进行调查，结果表明，四季蜜龙眼春季修剪较重，但夏季树体恢复较快；夏季成花调控成花株率为100%，成花枝率高达99%，冬季挂果率为90%；果实于11月中旬至12月上旬成熟采收，可溶性固形物含量为23.8%，可食率达68%，平均亩产500kg，销售价20-24元/kg，取得较好的效益，具有广阔的推广应用前景。     

Nonlinear Science and Control about the Geological Hazards in the Three Gorges Reservoir Area

Such the geological hazards as landslide, rockfall, debris-flow and so on frequently occur in the Three Gorges Reservoir Area, so it is a very practical and immediate job to explore the mechanism caused the geological hazards and how to forecast and control the geological hazards. For this reason, this paper introduces the situation of the geological hazards occurred in the Three Gorges Reservoir Area and the major type and feature of the geological hazards occurred in Chongqing, and discusses the basic principle about the modern nonlinear science applied to the geological hazards and the creep-slip, stick-slip occurred on the joints of rock mass and the monitoring technology of the geological hazards.The basic thinking is put forward which can be applied the modern nonlinear science to the geological hazards occurred in the Three Gorges Reservoir Area.     

Real-time Vehicle Scheduling

The traditional scheduling for vehicle is option in the fixed network. But it can't satisfy the real time environment. The demand of order is changeable and uncertain in real environment. It is convenient for scheduling transforming it into static data, but can't get the advantage on time. This paper proposes a real time vehicle scheduling on the study of traditional scheduling and discusses the model structure and the key technology for the real time system that establishes the base for develop teal time system.     

Knowledge Representation for Rotative Machine Fault Diagnosis Based on Semantic Net

Aiming at knowledge representation problem of expert system for rotary machinery fault diagnosis, semantic net knowledge representation is discussed. Semantic net to represent expert knowledge of rotary machinery fault diagnosis is explored. Its realizing method is afforded in computer language, in addition, demostrating model is also developed in Visual C++. The result shows good validity of the knowledge representation.     

Data Loading Technology of Data Warehouse

Data warehouse is not the simply data accumulation of operational database. For exerting the function of data warehouse, the construction of data warehouse should be convenient for the data mining and business intelligent work, supply information access, analyze, and share for decision maker. The key to constructing a successful data warehouse is to fully understand the demand of end users from beginning to the end, search and storage data surround users motive closely. This paper first analyzes the data warehouse characteristic and the sort of data component, emphasizes in effective data loading methods and strategies from operational database to data warehouse, gives five sorts data loading methods.     

厌氧悬浮颗粒污泥床同时反硝化产甲烷研究

利用厌氧悬浮颗粒污泥床反应器，以自配水为基质，通过微生物的反硝化作用和产甲烷作用成功实现了在单级反应器中去除硝酸盐和水中有机质的目的。反应器开始接种的污泥是产甲烷颗粒污泥，通过不断提高进水中硝酸盐的浓度，使厌氧颗粒污泥逐渐适应水中的硝酸盐，反硝化剩余的有机碳源转化为甲烷气体。在硝酸盐负荷为0.75kgN03^- -N·m^-3d^-1和COD负荷为14.1kgCOD·m^-3d^-1的稳态下，硝酸盐和有机碳的去除率分别为99.5％和90.1％以上。对反应器产生的气体所进行的气体组成测试表明，加入的硝酸盐全部转化为氮气，这一结果表明发生了真正的反硝化反应。     

海南不同地区香蕉假茎象甲对几种杀虫剂的敏感性测定

采用虫体浸渍法，测定了海南澄迈和儋州两地的香蕉假茎象甲成虫对480克/升毒死蜱EC、77.5%敌敌畏EC、40%辛硫磷EC、40%丙溴磷EC、25%丙溴?辛硫磷EC、20%三唑磷EC等6种杀虫剂对的敏感性。结果表明，6种药剂对澄迈和儋州两地区的香蕉假茎象甲的毒力大小顺序相同，毒死蜱＞丙溴?辛硫磷＞丙溴磷＞三唑磷＞敌敌畏＞辛硫磷；儋州地区的香蕉假茎象甲对6种药剂的敏感性均高于澄迈地区。
