Murawski 意译：硅藻属类海产品，现在已经放大200倍，看起来外形像一伸长的叶片。

This insidious mechanism, which does not deter the herbivore from feeding but impairs its recruitment, will restrain the cohort size of the next generation of early-rising overwinterers. Such a transgenerational plant–herbivore interaction could explain the recurringly inefficient use of a predictable, potentially valuable food resource—the spring diatom bloom—by marine zooplankton.

但是现在，用桡脚类动物Calanus helgolandicus所做的饲养实验表明，在硅藻与其捕食者之间在进行一场化学战：当被咬碎时，一些早期繁茂的硅藻会释放毒素，杀死以硅藻为食的桡脚类的后代；这样虽然不能阻止桡脚类继续吃硅藻，但却能影响其&兵员补充&，限制来年较早复苏的过冬者的数量。

Results showed that there were 73 species of phytoplankton belonging to 6 phya, in which scenedesmus and diatom were predominant.

The feature of this product is that diatom is taken as cereal or additional feed, so that stable and high yields can still be achieved even without feed or with 30 to 40 percentage of feed cut down; the outstanding social ecological economic benefits are brought by using this factory's products instead of medicines for curing disease in pond.

We have no common name for a mime of Sophron or Xenarchus and a Socratic Conversation; and we should still be without one even if the imitation in the two instances were in trimeters or elegiacs or some other kind of verse--though it is the way with people to tack on 'poet' to the name of a metre, and talk of elegiac-poets and epic-poets, thinking that they call them poets not by reason of the imitative nature of their work, but indiscriminately by reason of the metre they write in.

索夫农 、森那库斯和苏格拉底式的对话采用的模仿没有一个公共的名称；三音步诗、挽歌体或其他类型的诗的模仿也没有——人们把&诗人&这一名词和格律名称结合到一起，称之为挽歌体诗人或者史诗诗人，他们被称为诗人，似乎只是因为遵守格律写作，而非他们作品的模仿本质。
