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。

The applied phytosanitary treatments for pest control were based on the application to the whole study area, without distinction among sectors, of the mating disruption technique to control tortricids, and botanical and biological insecticides such as Ryanhia speciosa, Derris ellíptica, Bacillus thuringiensis and mineral products such as oil, sulfur and lime sulfur.

应用检疫治疗病虫害防治现状的基础上，应用到整个研究区之间的差别，而中断的领域，tortricids技术来控制交配，植物和生物农药，如Ryanhia Derris芽、叶elliptica绿和矿产品如油、硫和石灰硫。

Verdure of etiolation iris lamina is like a sword, design and color is gorgeous and large, have dance like flying Yan Qunfei, beautiful beautiful clinking, extremely rich appeal, can decorate the water wet place by the side of the Chi Panhe in gardens or shallow water area, already considerable leaf, yi Ke watchs a flower, it is to view and admire the hydrophyte with very high value.

黄化鸢尾叶片翠绿如剑，花色艳丽而大型，如飞燕群飞起舞，靓丽无比，极富情趣，可布置于园林中的池畔河边的水湿处或浅水区，既可观叶，亦可观花，是观赏价值很高的水生植物。

Parthenolide is extract from feverfew, it's main component is sesquiterpene, it is commanly used in west country and is mainly used to therapy skin infection, rheumatic disorder, migraine. But recent research indicate that parthenolide can regulate many pathway of signal in the cell, inhibit the cyclooxygenase, TNF-α, interleukin-1 expression induced by lipopolysaccharide in macrophage, inhibit the iNOS expression in human monocyt, inhibit the activity of NF-κB in Hela cell, inhibit the growth of tumor cell and can relieve the myocardial ischemical reperfusion injury and so on. But the invention research about the effection of parthenolide on the VSMC is very rare in the world, so we do some research about the effection of inhibition of parthenpolide on the proliferation of VSMC and the signal transduction mechanism.

小白菊内酯(parthenolide，又名Sesquiterpene lactone)是艾叶菊属黑叶母菊的提取物，主要成分是倍半萜烯内酯，西方国家较为常用，主要用于治疗皮肤感染、风湿病和偏头痛，但近年来发现小白菊内酯能调控细胞内多种信号途径，如抑制巨噬细胞中脂多糖诱导的Cox，肿瘤坏死因子α和白细胞介素-1的表达，能抑制人单核细胞中iNOS的表达，能抑制Hela细胞中NF-κB的活性，抑制肿瘤细胞的生长，同时能减轻心肌缺血再灌注损伤等，但小白菊内酯在VSMC中的干预研究目前国内外非常罕见，为了确切评价小白菊内酯对血管平滑肌细胞增殖的抑制作用及相关的信号转导机制，我们进行了一些研究。

If without dissipation, the propagation is essentially a symplectic transformation with one parameter, and, consequently, the numerical calculation methods of the propagation ought to be symplectic, too.

至今 ，已发展起来了许多方法，如计算走时的射线追踪法，计算全波场的有限差分法和有限元法等[1— 5 ]，以及随后发展起来的其他方法，如傅立叶变换法[6 ]、小波变换法[7，8]和各种结合算法[9，10 ]等。

John's wort, are often effective, but the idea is to use them like water wings, or training wheels on a bicycle, providing initial support, and giving time for other treatments, such as therapy, and relaxation techniques, to take effect.

草药疗法，如缬草，（这是没有使用，如果抑郁症也是本）西番莲，贯叶连翘，往往是有效的，但想法是用他们喜欢水的翅膀，或培训车轮骑自行车，提供初步的支持，并给予时间，其他治疗方法，如治疗，放松技巧，才能生效。

The result of clustering based on quantitative data of vessel elements suggests that the Sonneratia species evolved into two clades, one including S. caseoalris and S. paracaseolaris that has the wider vessel and lower pore density suggesting a high conducting efficiency, the other including S. alba, S. ovata, S. apetala and S. hainanensis that has the narrower vessel and higher pore density resulting in high conducting safety.

导管数量特徵的聚类分析可以推测海桑属植物沿两支进化，一支进化为水分输导效率高的种类（即导管直径宽和输导面积大，管孔密度小，如海桑和拟海桑），另一支进化为水分输导安全性高的种类（即导管直径窄、输导面积小，管孔密度大，如杯萼海桑、卵叶海桑、无瓣海桑、海南海桑）。

In the negative and interrogative forms, of course, this is identical to the non-emphatic forms.

。但是，在否定句或疑问句里，这种带有"do"的方法表达的效果却没有什么强调的意思。
