The main results are as follows:① The contents of the seven elements in both the mosses and the substrates are much higher than those normal condition;② Didymodon fallax has stronger capacity to accumulate the element Cd. It can be as the indicator of Cd;③ Comparing with the other 4 mosses, Bryum dichotomum possesses stronger enriching function for Cu, Zn, and Pb.

They also showed that large Cladocera size is more important than their number for efficient phytoplankton control and when cladocerans are large enough, they can considerably restrain phytoplankton growth, including bloom-forming cyanobacteria, even when submerged vegetation is not restored.
同样,它们也显示了大型枝角类的体型相对于它们的数量就对浮游植物的有效控制上意义更大。当枝角类足够大时,它们能够限制浮游植物的生长,包括蓝藻的爆发,即便当沉水植被没有及时恢复。

Low temperature ordering of FePt thin films has been achieved by using a thin equiatomic AuCu underlayer.
提出并利用相干生长的多层膜中有序-无序转变过程的彼此关联作用,借助AuCu缓冲层的低温有序化,降低FePt薄膜的有序转变温度200℃以上,为FePt薄膜的低温有序化开劈了一条新途径;制备多层膜,退火形成有序相FePt纳米颗粒分散在Ag基体的复合结构,比FePt/Ag共溅射或合金多层膜方法的退火温度明显降低;通过缓冲层Ta控制FePt的粗糙度和晶界密度,同时界面附近Ta、Pt发生化学反应,两者共同促进薄膜内Pt原子的有效迁移,从而加速FePt有序化;进一步,在Ta和FePt之间插入Bi薄层,强化Ta、Pt的扩散,在更低温度下形成高矫顽力的有序化FePt薄膜且FePt晶粒之间交换作用大大减弱;发现MgO薄膜作底层,可控制与MgO晶粒尺寸大致相当的临界厚度以下的FePt有序化薄膜的(001)取向,同时,MgO和FePt的相对厚度显著影响(001)取向FePt的有序化。

In this research, we consider that the predominant bacteria in low temperature wastewater treatment in winter were cold-adapted microorganisms, the number of which increased as the temperature dropped more and more, but rarely high up to the number of mesophilic bacteria in normal temperature due to its low growth rate and the restriction of ecological factors, so that the total number and activity level of microorganism in activated sludge decreased.
随着污水温度的降低,污泥中冷适应微生物的数量逐渐增加,但由于冷适应微生物的生长速率相对较低,且容易受到各种生态因子的抑制作用,其数量无法达到常温下中温微生物的水平,使得污泥中微生物的总体数量和活性降低。
