浮游植物 phytoplankton(1953)   phytoplankton     Nutrient Absorbing Kinetics and Growth Changes of Phytoplankton Controlled by Different Irradiance, Nitrate and Phosphate Concentration Levels on Autumn in Yangtze River Estuary     秋季长江口不同辐照和氮、磷浓度水平下浮游植物营养盐吸收动力学及生长变化研究 短句来源     Characteristics of phytoplankton population, the nutrient absorption kinetics and growth variation of phytoplankton were studied in this dissertation based on in situ controlled incubation experiment, which were conducted under the coupling between different nutrient concentration and different irradiance in the water region of the Changjiang River estuary.     本文通过在长江口水域进行的现场受控培养实验，对长江口浮游植物种群特征以及对不同浓度氮、磷和不同光照梯度耦合作用下长江口浮游植物营养盐吸收动力学和生长的变化进行了研究。 短句来源     1. The uptake rates of phosphate and nitrate by phytoplankton were mainly influenced by light.     1．浮游植物对氮、磷的吸收速率主要受光照的影响。 短句来源     2. The growth rates simulated by biomass which represented by Chl a were greater as the irradiance intensity became strong, and in situ irradiance couldn't restrain the growth rates of phytoplankton.     2．对以叶绿素a为代表的生物量变化拟合得到的比生长速率分析显示：随着光照强度的增加，比生长速率不断增大，现场光强对浮游植物没有抑制作用。 短句来源   “浮游植物”译为未确定词的双语例句     Correlations Between Reflectance Spectra and Contents of Chlorophyll-a in Chaohu Lake     巢湖浮游植物叶绿素含量与反射光谱特征的关系 短句来源   相似匹配句对     Correlations Between Reflectance Spectra and Contents of Chlorophyll-a in Chaohu Lake     巢湖浮游植物叶绿素含量与反射光谱特征的关系 短句来源     1.

The species number and biomass of algae under weak water flow (0.124m·s -1 ) were highest in the experiments. This was coincided with the low ratio of NO 3/TDN. The algae abundance was increased from the stationary state to the strong water flow (0.319m·s -1 ) state, the corresponding TDN/TN, TDP/TP were decreased at the same time. The photosynthetic rates from the stationary state to the ...             从静止状况到小水流、大水流的模拟水动力实验表明 ,水动力对湖泊生物群落演替起重要作用 .藻类种类数以小水流时最高 ,其生物量也最高 ,这与NO- 3 /TDN比值相一致 .由静止状态到大水流状态 ,藻类数量呈现递增趋势 ,这与相应的TDN/TN、TDP/TP呈递减趋势相呼应 .浮游动物的种类、数量的变化较之浮游植物更明显 ,尤其是枝角类的变化更大 .动力作用通过增加水体中悬浮质、降低透明度、改变水下光照条件及理化与生物过程释放营养物质 ,致使浮游植物、浮游动物群落结构、数量发生改变 文摘来源          The composition and activity of alkaline phosphatase in waters with different PO 3- 4 P concentrations were studied experimentally. The results show: ①The total alkaline phosphatase activity (TAPA) was decreased with the increase of PO 3- 4 P concentration ( r =-0.586, n =55). Based on the statistic analyses, when PO 3- 4 P concentrations were between 0 to 0.010mg·L -1 , no significant difference was found in the TAPA.
