The phytoplankton community was mainly composed of Cyanophyceae, Euglenophyceae, Bacillariophyceae, and Chlorophyceae, and the dominant species were Oscillatoria subtillissima, Dactylococcopsis irregularis, Euglena caudata, Melosira granulata, Cyclotella meneghiniana, Chlorella vulgaris, and Scenedesmus quadricauda. The main environmental factors affecting the distribution of phytoplankton species in July were ammonium-nitrogen, dissolved oxygen, water temperature, and total phosphorus, while those in September were pH, water temperature, dissolved oxygen, transparency, and total nitrogen. Water transparency and zooplankton were the main factors affecting the biomass of Cryptophyceae, Pyrrophyceae, and Bacillariophyceae; while nitrogen, phosphorous, and dissolved oxygen were the main factors affecting the biomass of Cyanophyceae, Euglenophyceae, and Chlorophyceae.

结果表明：调查期间共鉴定出浮游植物384种，隶属于8门，浮游植物密度范围为2.01×105～57.60×105 cells·L-1；群落组成以蓝藻、裸藻、硅藻和绿藻为主，主要优势种有细微颤藻、无常蓝纤维藻、尾裸藻、颗粒直链藻、梅尼小环藻、普通小球藻、四尾栅藻等；7月影响浮游植物分布的主要环境因子依次为铵态氮、溶解氧、水温和总磷，而9月的pH值、水温、溶解氧、透明度和总氮含量对浮游植物的分布产生影响较大；其中，透明度和浮游动物量是影响隐藻、甲藻和硅藻藻类生物量的主要环境因子，而蓝藻、裸藻、绿藻主要受水体氮磷营养盐浓度和溶解氧的影响。

How to do this is: the series-water roll clamping in grinder, head of the bed with a fixed Center, bed end, respectively, with huoluo thimble, despite a string of water both ends of the roll Center always ends up in l, with a dial check and correction of water roll radial runout of excircle and the tiaodong of error control in 0.02mm, to achieve accuracy requirements.

Based on the water resources survey of Shanghai in 1999 and the 1:50 000 color infrared aerial photos obtained in early 2000, a case study of the upper Huangpu River was carried out. The exponential method, pair-sample t test, and remote sensing analysis are used to analyze water environmental characteristics and land use pattern in the river network plain. In order to explore response of water quality in the waterhead region to the changes in land use and its driving force, five land use patterns are selected and a new type of exponential is designed.

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.
