Furthermore, it is concluded that wind waves and tidal currents are the two predominant factors related to sediment resuspension and control of the changes of suspended sediment concentration, in which tidal currents control the neap-spring tidal cycle, and wind waves control the seasonal fluctuation.

进一步分析认为，海洋动力是泥沙再悬浮的主导因素，制约悬沙浓度的年内变化，其中潮流控制悬沙浓度的大小潮周期变化，风浪引起悬沙浓度的季节性变化，河流径流和海洋动力的对比制约悬沙浓度的空间分布。

It was found that the bioaccumulation of Ct on Spirulina platensis involved two steps:rapid adsorption and slow absorption. Chromic compounds with weaker chemical bond had higher bioaccumulation efficiency. Under the same algal cell concentration, Crbioaceumulation rosed up with Crconcentration. On the other hand, with Cr concentration not changed, the total bioaccumulation of Cr on Spirulina platensis increased with algal cell concentration, but the Cr bioaceumu lation on unit algae reduced.

发现螺旋藻对Cr的生物富集主要经历了快速的吸附和缓慢的吸收两个步骤；化学键较弱的Cr化合物具有较高的富集效率；藻细胞浓度一定时，随着Cr浓度的增加，单位重量螺旋藻对Cr的富集量不断增加，最后趋于饱和；当Cr浓度一定时，随着藻细胞浓度的增加，螺旋藻对Cr的总富集量逐渐增加而单位重量藻体的富集量减少。

The results show that:First, concentration of hydrogen peroxide have the most obvious influence to oil yield and carbon black yield,with the increase of concentration of hydrogen peroxide the oil yield first increase then decrease,when concentration of hydrogen peroxide is 8.19% or so,the oil yield reach to the biggest value, and with the increase of concentration of hydrogen peroxide carbon black yield decrese;Then,reaction time have more obvious influence to oil yield and carbon black yield,oil yield increase but carbon black yield decrease with the increase of reaction time;Thirdly,reaction tempreture have some influence to oil yield and carbon black yield,samely,oil yield increase but carbon black yield decrease with the increase of reaction tempreture;Finally,reaction pressure does almost no influence on oil yield and carbon black yield.

研究结果表明：过氧化氢质量浓度对产油率和炭黑产率的影响最为显著，产油率随过氧化氢质量浓度的提高先提高后降低，在过氧化氢质量浓度为8.19%左右时达到最大值，炭黑产率随过氧化氢质量浓度的提高而降低；反应时间对产油率和炭黑产率的影响也比较显著，产油率随反应时间的增加而提高，炭黑产率随反应时间的增加而降低；反应温度对产油率和炭黑产率也有一定的影响，产油率随反应温度的提高而相应地提高，炭黑产率随反应温度的提高而降低；在本文实验范围内，反应压力对产油率和炭黑产率基本上没有影响。

The results showed that the growth of Jinguang plum seedlings were remarkably restrained by salt stress. With the increasing of salt concentration, the plant height, leaf area, leaf fresh weight, leaf dry weight, stem dry weight and root dry weight were remarkably decreased, and the chlorophyll content, photosynthesis rate, transpiration rate and stomatic conductance in leaves were declined too, but the intercellular CO2 concentration was inclined.

结果表明盐胁迫抑制了金光杏梅幼苗的生长，随着盐浓度的升高，金光杏梅的株高、叶面积、叶鲜重、叶干重、茎干重、根干重均显著降低；叶片叶绿素含量、净光合速率、蒸腾速率、气孔导度亦显著降低，且盐浓度越高，下降幅度越大；细胞间隙CO2浓度随着盐浓度增加而增大，表明盐胁迫下非气孔因素是导致金光杏梅叶片光合速率下降的主要原因。

The results show that uniform CdS spheres with 500 nm can be synthesized with controlled concentration of PVP; the greater the concentration of PVP, the greater the diameter of particles, and the more homogeneous the particles; microspheres are composed of small substructural CdS crystallites, and the greater the polymer concentration, the smaller the diameter of substructural crystallites.

结果表明，控制高聚物的浓度可以制备得到直径在500nm的单分散硫化镉微球；高聚物浓度在一定范围内，微球的直径随浓度增大而增大，且分散性越好；微球是由硫化镉的微小单晶沉积而成的，随着高聚物的浓度增大，单晶的尺寸越小。

This article mainly deals with Cr's pollution affecting the content of Cr,K,Mg,Fe,Mn,Zn,Cu,Mo in floating and underwater leaves of Trapa bispinosa .

研究 Cr6 +污染后菱浮水叶和沉水叶中 Cr、K、Mg、Fe、Mn、Zn、Cu、Mo元素的含量，结果显示：Cr含量随培养浓度的上升而上升，K、Mg随培养浓度的上升而下降，Fe含量随培养浓度的上升而出现先上升后下降，Mn、Zn、Cu、Mo与 Cr6 +的培养浓度无明显的相关关系。

According to the results, the germicidal efficacy was influenced by the concentration of ethanol, concentration of Tryptone Soy Brothculture medium and contact time of bacatericide. The optimal treatment for inhibition of the growth of pathogenic bacteria bioflims by ethanol was: ethanol concentration of 70%, contact time of 40 min and in 0%TSB.
