The N input from rainfall in HPA was about 3 to 4 times higher than that in LPA and CK. However, the biomass of vegetables in HPA was decreased by up to 40%, when compared with that in CK, thus leading to a significant decrease in N output through crop harvesting. As a result, a large proportion of N was sequestrated in the soils subjected to acid rain, which subsequently enhanced nitrate leaching posing a risk to water environment.

在酸沉降重污染区，降水输入系统的氮远大于轻污染区和对照区（约3~4倍），同时因酸雨危害，蔬菜产量明显低于对照区，仅为对照区产量的60%，使系统中通过作物收获的氮输出减少，结果导致大量氮滞留于土壤中并以硝态氮等形态淋失，给水环境带来了氮污染风险。

The results shoed that the total tree biomass in the transects adjacent the road was slightly higher than that of the inner forest communities, showing a positive edge effect, while the soil acidity and total nitrogen content in downgrade transects showed a negative edge effect.

结果表明，紧邻道路两边样带的乔木总生物量略高于群落内部，表现出边缘的正效应。道路坡下边缘土壤的pH值较高，全氮含量最低，边缘效应为负效应。

Based on the values of maximum specific growth rate, biomass and viable cells count in different cultural conditions, the optimal growth condition was regarded as follows: Glucose level of the medium was 80 g/L ~100 g/L; The pH was kept constant at 5.9 with aqua ammonia and anaerobic condition was kept by sparged with nitrogen periodically; The temperature was set at 37°C and cultured for

casei Zhang较适宜的高密度培养条件为：培养基葡萄糖浓度为80 g/L~100 g/L，以氨水为中和剂使pH保持5.9，采用间歇通氮气的方法保持环境厌氧，分批培养方式下37°C保温发酵10 h~12 h后，L。

The most promising approaches involve subjecting the biomass to extremes of pH and temperature.

最有希望的办法涉及以生物量，极端的pH值和温度为条件。

The total biomass of ephemeral macroalgae differed considerably among different types of substrata.

试验结果表明不同类型底质上的一年藻类的总生物量变化显著；在固定底质上生长的一年生藻类的生物量显著的高于附着于大型多年生藻类上的。

Form north to south, the biomass of dominant plants were significantly different among different sampling transacts.

我们在植物生长高峰期调查了崇明东滩北、东、南部6条样线上的高潮区、中潮区和低潮区滩涂植被。

Form north to south, the biomass of dominant plants were significantly different among different sampling transacts.

在高潮区滩涂，样带距潮沟边缘的距离显著影响植物的物种数与香农威纳多样性指数，而在中低潮区滩涂的调查则发现潮沟垂向方向上植物物种多样性的变化并不明显。

The relations between plant biomass and the distance to creeks were different at different transacts.

目前海三棱藨草仅在东部至南部低潮区的前沿地带仍有生长，且其带宽很窄，仅20－40米。

Results showed that shoot biomass of H. annuus was significantly higher than that of R. acetosa and R. hastatus; among three plant species, 134Cs specific activity in shoots was the highest in H. annuus after 50 d-treatment, however after 70 d-treatment, that in R. acetosa was the highest. Bioaccumulation ratio reached 1.5, 1.4 and 1.3 in R. acetosa, R. hastatus and H. annuus after 70 d-treatment, and the former two plants kept with trend of continuously increasing. Three plants were resistant to 134Cs contaminated soil and capable of translocating 134Cs from soil to plants. Among them, H. annuus removed greatest 134Cs amount in the aboveground part during the experiment period, and R. acetosa, R.

结果表明，向日葵地上部生物量显著高于酸模和戟叶酸模；处理50d时，向日葵地上部134Cs比活度在3种植物中达到最高，而在处理70d时，酸模地上部134Cs的比活度达到最高；处理70d时，酸模、戟叶酸模和向日葵对134Cs的富集系数均大于1，分别达到1.5、1.4和1.3，且前2种植物继续保持快速上升的趋势。3种植物对铯污染土壤具有一定的忍耐性，并具有较强的从土壤向植物转移铯的能力；在本实验期内（70d）向日葵对土壤中放射性铯的剔除能力最强，而酸模和戟叶酸模则具有更强的铯转移能力。

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