亚硝酸

The different light treatment had no obvious effects on the growth of fungus mycelium and spore germination. Sucrose, niter and subniter were the best C and N sources in axenic culture of the pathogen.

病原菌在不同光照条件及在不同碳、氮源上均能生长，不同光照条件对其影响无显著差异；以蔗糖为其最适碳源，亚硝酸

First of all, the start-up of the nitrous nitrification bioreactor and ANAMMOX bioreactor were tried out successfully.

首先成功的完成了亚硝酸型硝化反应器和ANAMMOX反应器的启动。

In this solution, it also could electrocatalysis the reduction process of nitrite.

实验中发现该化合物能对亚硝酸根的还原起催化作用。

The method has been used for the determination of trace nitrite in water and soil samples with satisfactory results.

用於水体和土壤中痕量亚硝酸根的测定，结果满意。

The method has been used for the determination of trace nitrite in water.

方法已用于水中微量亚硝酸根的测定。

The method was applied to determination of nitrite ion in water samples.

方法已用于水中微量亚硝酸根的测定。

But, this kind of condition would only occurred when a great deal of nitrobacteria are added into the water.

1去氨硝化菌能将鱼类所排放的氨转成毒性较小的亚硝酸盐，而去亚硝酸硝化菌则负责将亚硝酸盐再转成毒性更小的硝酸盐，硝酸盐必须由换水的方式移除，像硝化细菌这类的细菌再作用时需要消耗水中的氧气所以也称好氧菌。

According to those limitations, this study would like to use the molecular biology method to enumerate the nitrobacteria in the sample fast and precisely. We use fluorescent in situ hybridization method.

基於上述原因，本研究希望以分子生物学的方法快速且精确的计数样本中硝化菌的数量，所采用的方式为原位萤光杂合法（FISH； Fluorescent In Situ Hybridization），针对铵氧化菌与亚硝酸氧化菌的16S rDNA设计一段专一性的探针。

The toxic effect of nitrite is presumed to be linked with free nitrous acid.

亚硝酸盐对聚磷菌的抑制作用主要与亚硝酸有关。

The optimization of the experimental conditions, such as temperature, time, concentration of nitrous acid and pH have been investigated.

采用正交实验法讨论反应温度、时间，亚硝酸浓度，溶液pH值等条件对解聚反应的影响。

According to the clear water experiment, aeration performance of the new equipment is good with high total oxygen transfer coefficient and oxygen utilization ratio.

曝气设备的动力效率在叶轮转速为120rpm～150rpm时取得最大值，此时氧利用率和充氧能力也具有较高值。

The environmental stability of that world - including its crushing pressures and icy darkness - means that some of its most famous inhabitants have survived for eons as evolutionary throwbacks, their bodies undergoing little change.

稳定的海底环境─包括能把人压扁的压力和冰冷的黑暗─意谓海底某些最知名的栖居生物已以演化返祖的样态活了万世，形体几无变化。
