Secondly, according to the stem and leaf anatomy, leaf epidermis, pollen morphology and floral development, it is found that there are no close relations between Acorus and Typhales, especially in the aspect of floral development. In the course of floral development of A. calamus, neither bracteloe primordium nor common primordium occurs in the whole course. Early development of the flower is strongly unidirectional. Three shield carpels develop into a pistil. In Sparganium fallax, each female flower has a bracteole. The bracteole primordium and the floral primordium originate from a complex structure. A single saccate carpel develops into a pistil. In staminate flowers, petal and stamen primordia initiate spirally.

菖蒲属与香蒲目的茎叶解剖特征、叶表皮特征、花粉特征及花器官发生特点等亦存在着明显区别，特别是花器官发生特点差异尤为显著，如菖蒲属花器官发生过程中，没有苞片原基，也不存在任何形式的复合原基，花被与雄蕊原基均以单向性方式发生，雌蕊由3心皮发育而成，具有"盾状心皮"的特点等，黑三棱属则有苞片原基发生，且苞片原基与雌花原基起源于共同的复合结构，雄花的花被原基和雄蕊原基均以螺旋状方式发生，雌蕊由单心皮发育而成，未发现有2或3个心皮原基或其痕迹的现象，体现出"囊状心皮"的特点。

Previous studies show different interneuron changes in different models of epilepsy, which are focused on the onset of epilepsy, but not the onset of the spontaneous recurrent seizures.

在不同癫痫模型和患者海马观察含PV、CR、CB中间神经元数量变化的报道已有较多，但既往的研究着重于颞叶癫痫的始发过程上，而对颞叶癫痫发生后向自发性复发性发作演变过程中这三种中间神经元变化的研究较少。

Molecular homology trees were constructed based on the amino acid sequences of the RdRp,CP and MP,and the results showed that TVDV shares much more homologous with the specieses of the genus Polerovirus than other genuses of family Luteoviridae,which indicated that TVDV should be a definitive member of the genus Polerovirus in the family Luteoviridae.

根据三个ORF编码的氨基酸序列构建的分子同源树的分析，也都显示了TVDV与黄症病毒科马铃薯卷叶病毒属病毒的同源性最高，进一步证实了TVDV应该是黄症病毒科马铃薯卷叶病毒属的确定成员。

The perturbation methods are the common analyzing method for studying thevibratory response of the mistuned bladed disk, but different perturbation methodshave their own relying conditions on the system parameters. In this dissertation, threekey perturbation methods are studied for their application conditions. Their relyingconditions on the system parameters are summarized.

本文对三种常用摄动法的构造特点及其适用性进行了研究，总结了它们在分析失谐叶盘系统振动响应时对于系统参数的适用条件；针对自适应摄动法在分析失谐叶盘系统振动响应时，对于基系统模态的选择难以控制的问题，提出了一种模态自动选择法。

The objective of this paper was to study from three aspects, respectively: Breeding of transgenic rice restorer line for multiple resistance against bacterial blight, striped stem borer and herbicide; Marker-assisted breeding of pyramiding rice fragrance gene and multiple bacterial blight resistance genes; Molecular mapping of transgene cry1Ab in transgenic rice.

本论文主要开展了三个方面的研究：多抗性(抗白叶枯、螟虫、除草剂)转基因水稻恢复系的培育；水稻香味基因与抗白叶枯基因的聚合育种；转基因水稻中转cry1Ab基因的分子标记定位。

The short-day effect is recepted by theleaves of M.charantia seedling.The first pair of shield-shaped opposite leavesof balsam pear seedling are slow to short-day effect.while the third and forthpalm-shaped alternate leaves are most sensitive to the photoperiod.

苦瓜幼苗中对短日反应的感受部位是叶片，它的第一对盾形对生真叶对短日的反应比较迟钝，而第三、四片掌状的互生真叶对短日最为敏感。
