氮的

The essay introduces a new way to measure the total nitrogen of surface water in ion chromatograph .

本文提出了采用离子色谱法测定地表水中总氮的新方法，对离子色谱条件和流动相的选择进行了研究，方法具有良好的精确度、准确度，用于实际样品分析，结果令人满意。

One of those ways, associated with higher crop yields, is to be sure that limitations of some other nutrient do not detrimentally affect N uptake and use.

其中一个与高产有关的方法是保证一些其它养分的限制不对氮的吸收利用造成有害影响。

Despite their insolubility in many organic solvents, they are found to be soluble in nitrogen-containing solvents, such as DMF and pyridine.

这些化合物具有较好的稳定性，在胺类或其它含氮的有机溶剂中有较好的溶解度，如苯胺、二甲基甲酰胺或吡啶等。

Soil net N nitrification would increase with the increase of the %FNDA of Lespedeza bicolor. Lespedeza bicolor could fix a large amount of N〓, but was also likely to increase the N leaching loss.

胡枝子固氮作用越强，土壤有机氮的净硝化量就越大，胡枝子在从大气中获取大量〓的同时，很可能会增加氮素的淋溶损失量。

The purpose of this paper was to find a more suitable nitrogen application system for the cool season turf in Beijing area by using the lysimeter method.

本文的目的是为了研究北京地区冷季型草坪合理的施肥制度，了解尿素施用对混播草坪土壤中各形态氮的影响。

This may occur in response to a high level of reduced nitrogen in the medium.

这可能是由于对培养基中高水平的还原氮的反应而发生的。

On the basis of experiment results,and theory of soil water dynamics and solutetransport,mathematical models of NTT are established for the field conditions.

在试验的基础上，根据溶质运移理论及土壤水动力学原理，建立了田间条件下氮素运移与转化的数学模型，对田间淹水稻田和旱作农田中氮的运移、转化过程进行了数值模拟研究。

The liquid ink includes a carrier liquid, an organosol, and a colorant surface-treated by a polymer comprising units derived from at least a nitrogen-containing polymerizable monomer.

该液体墨水含有载体液体；有机溶胶；以及用聚合物进行表面处理的着色剂，该聚合物含有来自至少一种含氮的可聚合单体的单元。
