Three preliminary conclusions could be approached as follows:(1) SST changes were distinctively characteristic of stepwise fluctuations. A warming trend during the last deglaciation was punctuated by a slightly cooling event which corresponded to the Younger Dryas. The Holocene episode could be divided into three phases of warming, continuously high temperature and cooling.(2) Two remarkable cooling records were documented around 4 kaBP and 1.5 kaBP after the megathermal of the Holocene.(3) Comparison between time series of MD05-2904 diatom R SST index and stalagmite δ^18O results from Dongge Cave, Guizhou Province suggested that changes in the East Asian Monsoon climate is synchronous with variations in the SST in the northern SCS since the last deglaciation and they might have a close correlation with each other

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。

Distribution of biogenic silica content in surface sediments from deep water areas showed that it could not only reflect the paleoproductivity of siliceous micropaleontology in surface waters, but also indicate the strong or feeble upwelling. Thus, it was further confirmed that using biogenic silica content in sediments to trace upwelling and its change was effective and reliable. The analyzed result showed that radiolaria and poriferous specula have more contribution for biogenic opal, comparing with diatom in surface sediments from the northern studied area, probably owing to the diatom dissolved easily away and eaten by other organisms with little effort.
深水区表层沉积物中生物硅的含量分布表明,其不仅能反映出表层水体中硅质生物的古生产力水平,而且还能指示上升流的强弱,从而进一步证实了利用沉积物中生物硅含量来追踪上升流发育和变化的有效性与可信度研究结果还显示,在研究区域中北部表层沉积生物硅中放射虫和海绵骨针较硅藻占有更大的比重,这可能是由于硅藻易被溶解并易被其他生物体摄食的缘故。

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。
