In has a look at the industry aspect, industrial waste withdrawal various countries not to be dissimilar, this is, therefore the water which decided according to various countries' industry condition regarding the industry is very important, may see national indirectly from various countries fresh water resource total quantity the developed degree, simultaneously also looked at the process water size, the global process water reduced fresh water resource
在看看工业方面,工业废水的排放量各国的都不一样,这是根据各国的工业状况所决定的,所以水对于工业来说是很重要的,从各国淡水资源总量可以间接看出国家的发达程度,同时也看的出工业用水的大小,全球的工业用水又减少了淡水资源

The basal diameter, height of aerial stem, leaf length at middle stem, leaf width at middle stem, internode length at middle stem, internodes number and panicle length of 30 plants from every population were recorded. The statistics of morphological characters showed that the distribution trends of the averages of morphological characters are similar among populations. However, the coefficients of variation within population of 7 morphological characters were very different. The CV of internodes was largest and the CV of height was smallest within population. F-statistics showed that the differences of all morphological characters among populations were significant (P.01). But the differences among populations were different between different groups. The cluster analysis proved that all populations could be divided into three types: salty reed, freshwater reed and giant reed.
对来自每个种群的30个个体的基径、株高、中部叶长、中部叶宽、中部节间长、节间数、穗长7个形态特征的统计分析表明:各形态特征平均值在种群间的分布趋势相似,但变化幅度不同,株高、叶长等营养特征变化较大大,生殖特征穗长的变化较小;7个形态指标在种群内的平均变异度从大到小依次为中部节间长、中部叶宽、穗长、中部叶长、基径、节间数、株高,种群内的平均形态变异度与生境异质性有关;7个形态指标在种群间均差异显著,但多重比较分析显示显著差异主要存在于BZH、淡水生境种群和盐渍化生境种群之间,在相似生境种群间的形态差异不显著;以形态特征为依据的聚类分析支持将15个种群分为三类:盐生芦苇、淡水芦苇和巨型芦苇。

Physiological Responses of Hybrid Striped Bass to Aqueous Copper copper is an abundant trace metal, and although essential at low levels, it is also potentially toxic to aquatic organisms.Mechanisms of toxicity and consequences of exposure vary depending on ionoregulatory status(acclimated to freshwater or salt water).The goal of this research was to examine the responses of hybrid striped bass(Morone chrysopsXMorone saxatilis)exposed to Cu in freshwater and 15g/L salt water.In freshwater,a general dose-and time-dependent pattern of increasing Cu accumulation in gill tissue was evident in fish exposed to aqueous Cu(220 and 447 mg/L)for up to 96 hours.The 96-horu acute median lethal concentration for freshwater-acclimated hybrid striped bass exposed to Cu was 94mg/L(confidence interval=62 to 144mg/L).
生理反应到水的混合条纹鲈鱼铜是一个丰富的微量金属,虽然至关重要,它是在较低的水平也可能对水生生物有毒毒性机制及其后果的曝光取决于ionoregulatory状态,本研究的主要目的是为了检查的反应chrysopsXMorone混合条纹鲈鱼暴露于铜在淡水和15 / L盐水在淡水,一般dose-and时变模式日益增长的铜积累鱼鳃组织显然暴露于含水的铜(220和447毫克/升)长达96小时96-horu致命的平均浓度为freshwater-acclimated急性混合条纹鲈鱼暴露于铜被94mg / L(=置信区间来144mg / L)62 osmolatity、钠浓度降低。
