藻类

This paper listed a great number of records of dinoflagellate cysts with transapical ar-chaeopyte suture in marine and nonmarine deposits and pointed out that the cysts with this structure could be divided into two types which represented respectively two branches of later Cretaceous from marine pyrrophyta.One branch was represented by Palaeoperidi-nium with bipesioid type of reflection plate;the other was represented by Saeptodinium with bipesioid or cinctioid type of reflection plate.

摘 要：本文列举了大量具过顶古口缝的沟鞭藻囊孢在海相和非海相沉积中的记录，指出具这一构造的沟鞭藻囊孢可以细分成两个亚类，分别代表晚白垩世从海相多甲藻类家族中分化出的两个分支：一支以Palaeoperidinium为代表，具bipesioid型反映板式；另一支以Saeptodinium为代表，具bipesioid或cinctioid型反映板式。

Two species of algae, Chlorella pyrenoidosa and Scenedesmus obliquus were cultured by the method of Li Shanghao's .

Some conclusions were drawn: Oenanthe javanica grew normally when TN and TP concentrations in raw water were 7.05-9.99 mg/L and 0.29-0.73 mg/L respectively; with the hydraulic load being 0.5 m^3/(m^2d), the removal rates of NH3-N, TP, and TN from heavily polluted river water by Oenanthe javanica floating bed were positively related to water temperature, and it inhibited the growth of algae stably; the mean removal rate of nutritive salt increased with the concentration of raw water.

研究结果表明，进水ρ和ρ分别为7.05~9.99mg/L和0.29~0.73mg/L，水芹菜能正常生长，在水力负荷为0.5立方公尺/的条件下，水芹菜浮床对重污染河水中的NH3-N，TP，TN的去除率与水温正相关，对藻类的抑制作用稳定；营养盐的去除负荷随原水质量浓度的增加而增大。

The dynamic simulation test showed that, the removal rate of TN、 NH_3-N、TP of Oenanthe javanica floating-bed was positive correlated with water temperature. The average removal loading rate of TN and TP were 0.80g/m.~2·d and 0.11g/m~2·d, respectively. The inhibition on algae was steady and the average inhibition rate was 57.3%. We also got the best value of hydraulic loading rate, floating-bed coverage rate, water depth under dynamic polluted river. They were 1.0m~3/(m~2·d)、 30%、 30cm.

动态模拟试验表明：水芹菜浮床对动态污染河水中TN、NH_3-N、TP的去除率与水温正相关，TN的平均去除负荷为0.80g/m~2·d，TP的平均去除负荷为0.11g/m2~2·d，对藻类的抑制作用较为稳定，平均抑制率为57.3%；获得了对动态污染河水最佳净化效果时的水力负荷参数为1.0m~3/(m~2·d)、浮床覆盖率为30%、水深为30cm。

Based on the national tenth five magnitude project — Suzhou City Water Environment Improvement and Synthesize Demonstration item, we carried out the static simulation test and the dynamic simulation test under the condition of heavy pollution loading rate and low transparency and dissolved oxygen in polluted river of suzhou ancient city district. These investigations were on the base of the formers' work. We analyzed the purification effects and rules of plant floating-bed technology on polluted river water, and also applied the technology to purify the polluted river water in Miaojia River. Conclusions were summed up in the following:The dominance plant option test was carried out among Oenanthe javanica, Lolium mutliflorum and Allium sativum under low temperature condition. The results showed that the Oenanthe javanica was the dominance floating-bed plant under low temperature condition. Its net removal rate of TN、 NH_3-N、 TP、 COD_ were 51.3%、 65.2%、 55.6%、 57.6%, respectively, and inhibition rate of algae reached 92.3%.

本论文以国家863重大科技专项——&苏州市城市水环境质量改善与综合示范&项目为依托，在前人研究的基础上，根据苏州古城区污染河道污染负荷重、透明度及溶解氧低的实际情况，通过静态、动态模拟试验，研究了植物浮床技术对污染河水的净化效果及规律，同时在苏州古城区内的苗家河开展了植物浮床技术净化污染河水的示范应用，得出了以下结论：(1)低温条件下对水芹菜、多花黑麦草、大蒜三种浮床植物筛选的试验表明：水芹菜是低温条件下浮床植物的优势种，其对TN、NH_3-N、TP、COD_的净去除率分别为51.3%、65.2%、55.6%、57.6%，对藻类的抑制率达92.3%。

The plant floating-bed technology application in Miaojia river showed that the water quality of the plant foating-bed technology applied had preceded evidently than the comparing water, though the water quantity was exchanged largely. There existed a micro-ecosystem at the root aera of floating-bed plant which mainly consists of organic grain, algae, zooplankton, zoobenthos. The mode of "Oenanthe javanica -Ipomoea aqutica" floating-bed mode application realized the whole year run of plant foating-bed technology on polluted water. Hence, the mode is suggested in the following application.

植物浮床技术在苗家河的示范应用研究说明：在水量交换较大的情况下植物浮床技术仍然使示范河段水质优于对照段；浮床植物根际区存在着以有机颗粒、藻类、浮游动物、底栖动物为网络骨干的根系微生态系统：&水芹菜-水蕹菜&浮床模式可实现四季净化污染河水的周年运转，在后续应用中推荐使用此模式。

And Scenedesmus Mey., which belong to Chlorophyta, came to dominate the phytoplankton population, insteading of Oscillatoria Vauch.

The experiments also showed that Eclean restrained the growth of some blue algae such as anabaena flos-aquae and Oscillatoria tennis and some green algae such as chlorella. vulgaris. This shows that the seaweed extract Eclean is very important and very useful in controlling the blue algae water bloom.

EClean对不同藻类的抑制性试验表明，EClean对蓝藻门的水华鱼腥藻(Anabaenaflos-aquae)、小颤藻和绿藻门的小球藻有明显的抑制作用，对绿藻门的斜生栅藻和裸藻门的血红裸藻的生长有一定的促进作用，显示出EClean对蓝藻性水华的治理具有重要意义。

Algae microorganisms in the water overpopulate because of the surplus nitrogen.

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.
