1·Change of phosphorus and nitrogen concentration in the leakage loss.

渗漏流失氮磷浓度的变化。

2·Standard nitrogen concentration in MS medium was enough for garlic cell growth and SOD production.

MS培养基的基本氮源已经足够满足大蒜细胞生长和SOD合成的需要。

3·The results showed thai the content of ergosterol in yeast cells decreased with increase of nitrogen concentration in fermentation medium.

结果表明，当培养基中含氮量增加时，酵母细胞内竞角固醇的积累减少。

4·The results indicate the maximal relative error between simulation values and observation values of total nitrogen concentration is 11.67%.

结果表明，地下水总氮含量模拟值与实测值最大相对误差11.67%。

5·Soluble nitrogen concentration in surface runoff from cultivated land is highest, and then is in runoff from village, barren grassland and orchard.

不同地表径流中的溶解态氮浓度的差别较大，村庄最高，其次是耕地、荒草坡、林果地。

6·Effect of nitrogen and ammonia content on the nitriding rate, the microstructure, nitrogen concentration and hardness distribution of the nitriding case were studied.

研究氨气和氮气混合气氛的成分对渗氮速率的影响，测定了渗氮层的显微组织、渗氮层氮浓度分布及有关力学性能。

7·Results indicate that the optical band gap of the CN x films is decreased with the increasing nitrogen concentration, accompanied with the reflectance increase of the films.

结果表明：随着薄膜中氮含量的增加，碳氮薄膜的光学禁带宽度减小，红外反射率增加。

8·The time of dynamic nitrogen adjustment were determined by regular patterns or by the comprehensive evaluation of soil mineral nitrogen concentration and rice population status.

氮素动态调控时期由高产栽培常用的追肥时期或根据水稻群体状况与土壤矿质态氮浓度综合判断确定，追氮量由模型计算获得。

9·High nitrogen concentration led to overgrowth of cells and overproduction of by-products, therefore, decrease of 1, 3-pd final concentration and conversion of glycerol to 1, 3-pd.

氮源浓度较高时会导致菌体过度生长和副产物的大量生成，降低1,3 - PD的最终浓度和甘油到1,3 -丙二醇的转化率。

10·Rainfall simulation experiment was performed to evaluate nitrogen losses from farmland and show the effect of fertilizer application on nitrogen concentration and losses of runoff.

在室内降雨模拟试验条件下，研究暴雨径流中农田氮素养分流失及施肥处理的影响。 结果表明，农田暴雨径流氮养分的流失量与累积径流量成正相关；
