睡莲

Once upon a time there lived a young frog who often sat upon a very soft lily pad.

从前有只小青蛙，经常坐在一片极柔软的睡莲叶子上。

There are fewer frogs than lily pad.

青蛙比睡莲叶子多。

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.

以这样的方式，负电荷向下跳跃，"先驱"一个接一个地就像是池塘中睡莲的叶子——一个搭着另一个。

For this reason I would like to borrow the examples of the "lily pad problem" that once troubled France and the "horse manure public hazard" that some British scholars warned people of during the Industrial Revolution.

因此，我想借用曾经困扰整个法兰西的"睡莲叶子问题"和在工业革命期间，某些英国学者警告人们的"马粪公害"的例子来做讲解。

Though this serene setting from Mark Word Design in west Texas features a swimming pool, we're most captivated by the gorgeous lily pad pond.

在德克萨斯西部，Mark Word Design打造出了这一片宁静的天地。虽然它的主要特色是有一个泳池，能让我们迷倒的却是漂着绚丽的睡莲浮叶的池塘。

These individual characters are similar to those of most aquatic plants in monocotyledonous Helodiales and dicotyledonous Nymphaeales, which reflects the phylogenetic relationships of Iris from aquatic plants to xerophil.

这些个体性状与单子叶沼生目和双子叶睡莲目多数水生植物相似，从一定程度上可以反映鸢尾属植物从水生到旱生的系统发生上的关系。

The lilies have gone too, the yellow small-headed kind that in bud are like swimming snakes, and the great reeds are going, woven by wind and frost into untidy basket islands under which coot and moorhen skid for cover at the sound of strangers.

睡莲凋零了，是黄色、花冠很小的品种，含苞待放时的身姿如水蛇游弋。风吹霜冻，芦苇也日渐枯黄，化成一座座蓬乱中空的荒岛；一有人声，黑鸭和雷鸟便躲进芦苇丛中。

The lilies have gone too the yellow small-headed kind that in bud are like swimming snakes and the great reeds are going woven by wind and frost into untidy basket islands under which coot and moorhen skid for cover at the sound of strangers.

只有那种黄色的花冠罕濉的睡莲还含包待放，它们摇曳时纺身姿如水蛇游弋。风吹霜冻，芦苇也大片大片地枯黄了，如同一坐坐蓬乱的荒岛。一有人声，黑鸭和雷鸟便躲进芦苇丛中，不见了踪影。

And wild Nelumbo nucifera ranked last, and combination of several aquatic macrophytes could keep good purification effect for a long period.

从单一水生植物的净化作用上看，水葫芦的净化效果最好，次之为睡莲和野生荷花，人工种植的荷花相对较差；多种水生植物的组合更有利于植物在净化作用上的优势互补，从而能始终保持较好的净化效果。
