| 2. | A study of the properties of atmospheric aerosol over lanzhou in winter and applications by using integrating nephelometer 应用积分浑浊度仪研究兰州城市冬季大气气溶胶 |
| 3. | Objective to study the function of electromagnetic fields on decrease turbidity value and fluoride in drinking water 摘要目的探讨复合电磁场降低水的浑浊度和除氟功能。 |
| 4. | Results the turbidity value and fluoride in water were reduced 98 % and 80 % ~ 85 % after treated by electromagnetic fields 结果复合电磁场对水样的浑浊度去除率达98 %以上,对氟化物去除率达到80 % ~ 85 % 。 |
| 5. | The main characteristics of maltodextrin include stability , hygroscopicity , viscosity , turbidity and gelation behaviour as well 摘要麦芽糊精的主要性质包括麦芽糊精的稳定性、吸湿性、黏度、浑浊度和凝胶特性等。 |
| 6. | Methods water sample was treated by electromagnetic fields , and the turbidity value and fluoride in water sample before and after treatment were detected 方法利用复合电磁场对实验室模拟水样和现场水样进行处理,检测处理前后水中的浑浊度、氟化物浓度,并计算去除率。 |
| 7. | The present character of the deep bay mudflat has been created over centuries by the pattern of water flow around the bay , and the level of silt in the water which deposits on the mudflat 后海湾的浑浊度和水文均是该地的重要特徵,亦同样具国际价值。湾内沉积物堆积和侵蚀的模式形成如今的泥滩。 |
| 8. | The suddenly intensified biological activities , led by the mixing of high mud - content freshwater and salty water and the rapid sedimentation of course , are believed to be responsible for the phenomenon . ulterior researches are needed for verifying and detailing the mechanism 主要原因是,高浑浊度的长江淡水输入,淡盐水混合和泥沙迅速沉降导致生物活动迅速加强的结果,其详细机制还有待进一步研究。 |
| 9. | For a given ph condition , adsorption of trace metals on to sediments in the changjiang estuary can be described by the langmuir equation , and implies that increase in trace metal concentrations at natural waters has limited effect on trace metal partitioning coefficients because of high turbidity . 5 在某一给定ph条件下,长江口悬浮泥沙对5种金属的吸附符合朗格谬尔关系,这表明,在高浑浊度天然水体中微量金属浓度的变化对它们在固-液两相之间的分配系数影响不大。 |
| 10. | From the research results , we can see that the initial reason , which leads to the degradation of xuanwu lake ecosystem , is pollution . pollution makes the water and sediments hypertrphiation , increases the opacity of water , and decreases the oxygen in water , so the wetland higher plant communities decrease or disappear . the wetland ecosystem loses the balance , while the biodiversity also decreases 研究结果表明,引起玄武湖湿地生态系统功能退化的初始原因是严重的环境污染问题,污染加剧了水体及沉积物中的营养盐含量,增加了水体的浑浊度,降低了水体中的氧含量,从而导致湿地高等植物群落减少乃至消失,尽而引起湿地生物多样性下降、生态系统失去平衡。 |
