藻类

Many motile algae are positively phototactic,e.g.Volvox.

The disadvantage is the unknown knock-on effects. Planktonic algae are at the bottom of the food chain.

浮游藻类位于食物链的底层，假如它们的数量增多，那食物链的其它部分将会受到影响。

螺旋藻细胞中的碘富集量与培养液中外加的碘盐的种类和浓度都有一定关系，KI是进行藻类富碘培养的适宜碘盐，最佳添加浓度为4000mg/L，在此浓度下，收获的螺旋藻细胞干重(255mg／L)约为对照组(241mg／L)的1。

The results show that the algal viabilities after freezing can rise remarkably through controlling preculture conditions, optimizing dehydration rates and dehydration degrees and improving recovery methods after thawing.

结果表明，通过控制预培养条件，优化脱水速率和脱水程度以及改进化冻后的恢复方法等措施，可以显著地提高藻类的冰冻保存存活率。

The stimu- lating effect of glycine on nitrate reduction was greatly influenced by preillumination treat- ment of tobacco leaves,and also by the activity of respiratory chain.

但乙醇酸脱氢酶主要存在于低等植物如藻类巾；在高等植物中，乙醇酸的氧化主要是由乙醇酸氧化酶催化的，形成乙醛酸和H言02，但没有还原剂的生成L19，。

It holds over 2000 strains of algae and protozoa which are supplied worldwide to industry and the academic community.

In this paper, the area in focus is Sungo Bay, one of the most large-scale aquaculture areas in North China. From the view of physical, chemical and biologic, mechanism of sediment resuspension and its ecological effect is studied; Moreover, the wave-current coupling model and prediction model of suspended sediment concentration is built.

本研究以我国北方重要养殖海湾——桑沟湾为研究对象，从物理、化学、生物三个角度出发，研究了沉积物再悬浮的发生过程以及再悬浮介质-沉积物的源汇转换角色及其与养殖藻类的关系，构建了波流耦合模型和再悬浮颗粒物浓度预测数学模型。

Na+/H+ Antiporter is one sort of protein which on the membrane or vacuole membrane, they can transport Na+ retrorsely out of the cell or into the vacuole.

Na~+／H~+运输蛋白是位于质膜和液泡上的一类运输蛋白，它可以逆电化学梯度将Na~+排出细胞外或区隔化于液泡中，普遍存在于藻类与盐生植物中。

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。

The relationship between communicative competence and grammar teaching should be that of the ends and the means.
