We deduced that the phenomenon of twin-ovaryand more stigmas in the forth whorls were from partly homeotic conversion of stamensinto pistils.

5根据花发育模型的推论根据花器官的ABC模型，突变体性状主要属于第3、4轮花器官的变化。

Because homeotic gene mutation and floral organ variation is a direct relationship,therefore the mutant application is the current functional genomics study developmentdirection. We discovered one mutant ah from line 458, which was a line ofthe twin-seedling strain W2555.ln this study, we have investigated the morphogenesisprogress, genetic analysis of mutant traits and molecular tagging of related gene.

目前，由于在水稻中发现的花器官突变体很少，所以对水稻花发育的研究主要是利用双子叶植物MAS-box基因的保守序列设计引物，在水稻基因组或者cDNA文库中筛选与双子叶植物花器官发育相对应的MADS基因，因为同源异型基因的突变与花器官的变异是直接对应的关系，所以突变体的应用是当前功能基因组学的发展方向。

The research of this thesis is under the circumstances that the international shipping center of Shanghai builds Yangshan deep water port project, first of all, through its SWOT analytical method analyze Shanghai maritime affairs situation, maritime affairs office existing boat policy, Yangshan deep water port hydrometeorological situation, analyze the present main ship type, to explain the background of the choice the ship the small waterline, to put forward the necessity of building small water-plane area twin hull maritime affairs patrol ships. Then, it introduces the principle, characteristic of the small waterline, and has analyzed the domestic and international state of development of the SWATH ship, and conclude that it is feasible to build SWATH maritime affairs patrol ship technical, through the research and analyze of design at home and abroad,; Then it analyzed the application of the SWATH ship in maritime affairs manage both at home and abroad, put forward the preliminary scheme, and carry on research to the economic performance of technology of the scheme, through putting forward the preliminary model of plan of design to main yardstick and selecting type of host computer finally after relatively optimize, and confirm design specifications .

本文的研究是在上海国际航运中心建设核心工程洋山深水港的大前提下，首先，通过利用SWOT分析方法分析了上海海事局面临的形势，对上海海事局现有航政管理船舶现状进行分析，对洋山深水港海域的水文气象情况进行了调研，对当前主要船型进行分析，对选择小水线面船的背景加以阐述，提出建设小水线面双体海事巡逻船的必要性：接着，对小水线面船的原理、特点加以介绍，并对小水线面船国内外发展状况进行了分析，对国内设计建造小水线面双体海事巡逻船的技术可行性进行了研究分析，得出国内设计建造小水线面双体巡逻船在技术上是可行的；然后对国内外应用于海事管理等工作的小水线面船型进行分析，提出初步的方案，并对方案的技术经济性能进行研究，通过对主尺度和主机选型等进行比较优化后最终提出初步的设计方案模型，并确定设计任务书。

The imitated twin-stage liquid impinger could be used to control the quality of inhalation product.

自制双层液体碰撞器可用于吸入剂的质量监控。

METHOD:Salbutamal and carrier particle deposition with various flow rate was characterized by means of a twin stage impinger.

以硫酸沙丁胺醇为模型药物，用双冲程试验仪评价不同的气流速度对吸入型粉雾剂在模拟肺部的沉降量。

Methods AH dry powder inhalation was prepared by spray-drying method. Following spray-drying, resultant powders were characterized using scanning electron microscopy and laser diffraction, and the aerosolisation performance was determined using twin-stage liquid impinger. The process conditions were optimized with orthogonal design combined with multi-index test. The powder yield, aerodynamic diameter, angle of repose and respirable fraction were used as indices for orthogonal design.
