The results show that the technical parameters and the concentration of sodium molybdate have obvious effect on the composition of the alloy. The crystal grain size is from 6.2 to 12.7 nm and changes with current density, temperature and the pH value of the electrolyte.The crystalline growth of the alloy accords with the model of three-dimensional growth. The surface morphology is mainly determined by the rate competitions between the growing direction of vertical surface and the expanding direction along the surface towards circumambient. The results of the X-ray data show the presence of the multiphase containing solid solution and intermetallic compound in the deposits. The deposit phases alter from the FeNi and FeMo solid solution to the FeNi and MoNi4structure at 3 A/dm2. The deposits internal stress increases linearly with the decrease of the grain size. The lattice parameter of the deposits are slightly distorted

结果表明：工艺条件和钼酸钠浓度对合金组成的影响较大；所得合金晶粒尺寸为6.2~12.7 nm，并随电流密度、温度和电镀液的pH值的改变而变化；合金的晶体生长符合晶核三维生长模型，镀层表面形貌由平行和垂直于基体的生长速度的相对大小决定；镀层物相为固溶体和金属间化合物的多相结构，当电流密度为3 A/dm2时，镀层物相由FeNi和FeMo固溶相转化为FeNi和

Phytoplankton biomass increase coincided with the decrease in large Cladocera density and size.

从中可看出浮游动物种类组成以原生动物为主，其次是轮虫，桡足类和枝角类最少，平均密度为3.98×10~3ind/L。

The results showed that the structure characteristics of block cloddy was with tight surface but loose inner, the bulk density of the crust can be high as 1.39~2.0g/cm^3, which was mainly affect by unreasonable tillage process. The tight surface can not be crushed by nature alternation of drying and wetting. Farming machinery to impact and rotary tillage were necessary when reduce them.

结果表明不合理耕作所产生的块状结构体具有外部极为密实而内部相对疏松的构造特征，外壳的容重高达1.39~2.0g/立方公分以上，仅依赖于自然干湿交替作用使其碎散成小的土团成为不可能，必须运用机械击打、旋耕切割等方法进行破碎。

When fed with the mixture of P. donghaiense and the diatom Nitzschia closterium, A. sauna preferred grazing on P. donghaiense to N. closterium, and the GCEs of A. sauna decreased with the increasing density of P. donghaiense. When exposed to A. catenella at the densities of 10 – 10^3 cells/mL, A. sauna lost weight with no Chlorophyll a detected in their guts, which indicated that A.
