睡莲

Euryale is very similar to Nymphaea in floral organogenesis, so it should be treated in the Nymphaeacea together with Nyphaea.

芡实的花器官发生与睡莲的基本一致，作者赞成将芡属和睡莲属一同置于睡莲科，不支持将芡属从睡莲科中分离出来。

In addition, the sister-group relationship between Nymphaea and Ondinea was supported by some trees. The sister-group relationship between Euryale and Victoria did not support thatEuryale can be promoted to an independent family.

此外，部分数据支持睡莲属与澳大利亚睡莲属构成姐妹群，而芡实属与王莲属的姐妹群关系不支持芡实属独立为芡实科的观点。

In conclusion, a comprehensive analysis of water lilies based on morphological and molecular data was performed, showing the phylogenetic relationships among the 10 genera and providing new evidence for classification at family level. The specific and infraspecific relationships within the genus Nymphaea were revealed using the ITS sequences, providing a new approach to germplasm identification and phylogenetic analysis of water lilies. The investigation of invasive fanwort in China may also provide a sound basis of its ecological studies.

总之，本文以国内外长期研究为基础进行了综合定量的形态学与分子序列分析，明确了10个属的系统位置，为科的划分提供了新的依据；通过运用ITS序列研究睡莲属的种及种下单位之间的亲缘关系，为睡莲类植物的种质资源鉴定提供了新的工具；对水盾草进行了初步的调查分析，为今后深入开展其生态学研究打下了良好的基础。

The difficult part of this "lily pad problem" is that people tend to assume that, if lily pads need 29 days to spread over half of the pond, it would probably take them a few more days to blanket the other half, while the terrible end will in fact come the day after.

"睡莲叶子问题"使人不解的地方使人们趋向于这样设想：如果睡莲叶子蔓延29天才超过池子的一半面积，那么覆盖其另一半可能需要更多的时间。然而，实际上，可怕的结果在第二天就来临了。

A frog's heaven, no doubt. Miasma, scum, pond lilies, stagnant water. Sit on a lily pad unmolested and croak all day. Something like that, I imagine.

无疑这是一个青蛙的天堂，瘴气、泡沫、睡莲和不流动的水，坐在一片没有人烦扰的睡莲叶子上呱呱叫上一整天—我设想天堂大概就是这样的。

PartⅡStudy on the chemical constituents of Nymphaea candidaNymphaea candida Presl is a herbaceous hydrophyte native to the southern Xinjiang in China,and the flowers of N.candida has been used as a folk medicine for head pains,common cold,cough,hepatitis and hypertension.

第二部分睡莲花化学成分及生物活性研究睡莲花Nymphaea candida Presl为睡莲科睡莲属多年生水生草本植物雪白睡莲的干燥花蕾，主要分布于我国新疆的南部地区，在维吾尔族民间用于热症引起的头痛、热感咳嗽及小儿急、慢惊风等病症的治疗。

On bright calm days they lie in thousands on the now darkening water mostly yellow flotillas of poplar floating continuously down from great trees that themselves shake in the windless air with the sound of falling water but on rainy days or after rain they seem to swim or be driven away and nothing remains to break the surface except the last of the olive- yellow lily pads that in high summer covered every inch of water like plates of emerald porcelain.

在风和日丽的日子里，白杨树叶伴着水流的节奏簌簌地落下，像一叶叶黄色的扁舟，成千上万地泊在这秋水中。在下育的日子里或育后时节，它们或游离此地，或随波逐流。平静的湖面上只剩下残存的黄绿色的睡莲叶子。而盛夏时，睡莲叶子宛如葱绿晶莹的瓷盘，覆盖着湖面的每寸水域。睡莲凋零了。

In this manner, the negative charge hops downward from leader to leader like a frog jumping from lily pad to lily pad across a pond.

负电荷的这种跳跃方式就好像青蛙在睡莲上跳跃一样，从这个睡莲跳到另一个睡莲，从而跃过池塘。
