  1. Towards the research on two flood water of yuhe river in datong city during 2004, by measuring and comparing their discharge, sediment concentration 、 nutrient include organic, phosphorus, potassium, azote, the result shows that the nutrient content of the sediment is greatly larger than that of supernatant fluid

    摘要以2004年大同市御河乾渠兩場洪水為研究對象，對其流量、含沙量、養分（包括有機質，氮，磷，鉀）做了測定和比較，研究結果表明：洪水中下層泥沙中的養分含量遠大於上清液中的養分含量；洪水中整體養分含量隨著含沙量的增大而增大，並且養分含量和含沙量呈近似線性關系。
  2. Analysis of change of the nutrient concentration in porewater with depth indicates the relation between the oxidative - reductive conditions and the nutrient concentration

    對沉積物中孔隙水營養鹽濃度隨深度的變化分析，表明了沉積物孔隙水中營養鹽濃度變化與氧化還原環境的關系。
  3. The toad nutrient of floods increases as the sediment concentration increases, and there is nearly a linear relationship between them, by analysing the particle size of the sediment, we can conclude that the reason of the liner relationship is the resourse of flood nutrient and the sediment nature

    通過對洪水中下層泥沙做顆粒級配分析，推斷出這種結果主要是由洪水養分成因及洪水中下層泥沙粒徑特性決定的。
  4. These values were compared with the n and p concentration in sediments and macrophyte biomass in order to assess nutrient availability, fate and storage capacity

    這些數值被用來與沉澱物和大型動植物中的氮磷濃度相比較，由此得出營養物質的有效性，去向和儲存量。
  5. Experiments of artificial rainfall showed that sediment is the main body of total nutrient loss and runoff is the main body of available nutrient loss when erosion is slight, but sediment become the main body of total and available nutrient synchronously while erosion is intense. concentration of nutrient in runoff is most likely to be affected by concentration in topsoil. the higher concentration in topsoil is, the more possible nutrient loss by runoff is

    人工降雨實驗結果表明，在降雨強度和侵蝕強度不大時，侵蝕泥沙是全量養分流失的主體，地表徑流則是速效養分流失的主體；而當在降雨強度和侵蝕強度極為劇烈時，侵蝕泥沙成為全量養分和速效養分二者流失的主要載體；地表徑流中的養分含量很大程度上受土壤中養分含量的影響，土壤中養分含量越高，養分徑流流失的可能性越大。
  6. The development of healthy concentrates includes various steps : 1. start with plants that are organically grown, high in nutritional value ; 2. harvest the plants when they reach their own peak nutrient levels ; 3. harvest and process within hours before the nutrients start to degrade ; 4. final concentration process locks in the nutrients

    有益濃縮素之生產過程有數個步驟： 1 .以有機方法種植高養分的植物； 2 .于植物營養最高時進行收割； 3 .于收割后數小時內處理原料，避免營養流失； 4 .進行最後濃縮工序以保留原料中的營養。
  7. Effect of nutrient elements on lead uptake of hyperaccumulators. a little amount nitrogen and potassium can accelerate the growth of spad and plant dry weights, advance the lead uptake of hyperaccumulators. but with the increasing of nitrogon and potassium concentration, the lead uptake of plants droped, and spad and dry weights rose constantly

    5營養元素n 、 p 、 k對植物吸收pb的影響少量的n和k會促進富集植物葉片葉綠素值和干重的增加，促進植物對pb的吸收，隨著n和k水平的增加，植物對pb的吸收能力降低，但k的抑制作用不如n的顯著，葉綠素值和干重一直在增加；土壤供p會降低植物對pb的吸收，且下降極顯著。
  8. The effect of cadmium - arsenic interaction on the wheat npt ( non - protein thiols ) concentration results showed that, in the nutrient solution with cadmium, with the increasing of cadmium concentration, the concentration of npt increased ; in the nutrient solution with arsenic, with the increasing of arsenic concentration, the concentration of npt increased

    鎘砷交互作用對小麥非蛋白巰基含量的影響研究發現，在鎘的單一作用下，隨著鎘濃度增高，小麥非蛋白巰基含量增高；在砷的單一作用下，隨著砷濃度增高，小麥非蛋白巰基含量也增高。
  9. Based on the field investigation of the wave and sediment suspension in taihu lake, along with sampling water by layer and analyzing the nutrient concentration change with depth, it was found that the nutrient concentration enhanced suddenly on the bottom. layer indicating the influence of sediment

    摘要通過在太湖開展的風浪與底泥懸浮的野外觀測，結合分層採取水樣並分析水體中溶解性營養鹽的濃度隨深度的變化結果，發現在水土界面的上覆水中營養鹽濃度有突然增加的現象，指示著沉積物對上覆水營養鹽濃度有影響。
