In addition,the protein-like and humic-like fluorescence changes fore and aft cross-flow ultrafiltration(CFF) were primarily evaluated.      利用荧光激发-发射矩阵光谱(Excitation-Emission Matrix Spectroscopy,EEMS)技术研究了胶州湾2004-02赤潮暴发期间水体中溶解有机物类蛋白和类腐殖质荧光特性,探讨了各种荧光性质与浮游植物增殖、溶解有机碳、盐度、溶解氧和pH的关系,并对切向超滤前后类蛋白和类腐殖质荧光的变化进行了初步评估. 短句来源   相似匹配句对      CHAPTER 4 MARINE BIOLOGY Section 1 Phytoplankton      浮游植物 短句来源      THE STUDIES OF PHYTOPLANKTON REPRODUCTION CAPACITY      浮游植物增殖能力的研究探讨 短句来源      Allelopathy in phytoplankton      浮游植物的化感作用 短句来源      X.      X上的增殖算子。 短句来源      Research on neutron multiplication formula      中子增殖研究 短句来源 查询“浮游植物增殖”译词为用户自定义的双语例句     我想查看译文中含有：的双语例句 为了更好的帮助您理解掌握查询词或其译词在地道英语中的实际用法，我们为您准备了出自英文原文的大量英语例句，供您参考。   phytoplankton reproduction The phytoplankton reproduction capacity (PRC), as a new concept regarding chlorophyll-a and primary production (PP) is described.PRC is different fromPP, carbon assimilation number (CAN) or photosynthetic rate (PB). 例句来源         phytoplankton blooms Bacterial proliferation in water masses usually succeeds to phytoplankton blooms. 例句来源       The dynamics of phytoplankton blooms in puget sound a fjord in the Northwestern United States 例句来源       This switch from herbivorous to carnivorous behavior may be significant in nature during the decline of phytoplankton blooms. 例句来源       Phytoplankton blooms appear off high islands at the beginning of the rainy season in bays with large watersheds and with sufficient residence time of the waters; these are the initial sites of A. 例句来源       I hypothesize that, on rare occasions, terrestrial runoff from heavy rains (following the dry season or a record drought) may provide enough nutrients to stimulate phytoplankton blooms of sufficient size to produce enough food for the larvae of A. 例句来源       更多                    The study on O_2, Co_2, pH, negative ions, positive ions and nutrient elements in the water have been carried out with general analysis method in this paper. There are diel changes of dissolved oxygen, carbon dioxide and pH in the water of pond, they are correlated each other. The special character of main ions in the water is :HCO_3~-+CO_3~(2-)>Ca~(2+)+Mg~(2+). The nutrient elements have diel and seasonal changes. The mean content of inorganic nitrogen is ab out 0.239mg/L and that of P_2O_5 is about 0.057m...             本文应用常规分析手段对池塘水体中的O_2、CO_2、pH、阴离子、阳离子及营养元素进行了研究。O_2、CO_2、pH值都呈现昼夜变化,三者间具有一定的相关性。主要离子含量的特点为:HCO_3~-+CO_3~(2-)>Ca~(2+)+Mg~(2+)。营养元素都具昼夜变化和季节变化。无机氮的平均含量为0.239mg/L,可溶性磷酸盐的平均含量为0.057mg/L,二者比值为2.62。总氮与总磷的平均含量分别为3.77mg/L和0.885mg/L,二者比值为4.26。与其它地区相比,三江平原池塘水体中磷含量高而氮含量过低已成为浮游植物增殖的限制因子。 文摘来源          In this paper, data of phytoplankton biomass and ecological factors analysed by linear regression found that, phytoplankton biomass with Ca~(2+) Mg~(2+), NO_3~+—N, NH_4~+-—N, total N, total P, COD and turbidity shows in linear dependence. The relationship between biomass of Chlorophyta and Mg~(2+), NO_3~-—N, NH_4~+—N, total N as well as COD is linear dependence.
