1. Studies by Hargrave and Geen estimated natural community grazing rates by measuring feeding rates of individual zooplankton species in the laboratory and then computing community grazing rates for field conditions using the known population density of grazers.
由哈格雷夫(Hargrave)和吉恩(Geen)所进行的研究，对自然条件下的群落捕食速率进行了估计，其手段是通过测量出实验室内单独的浮游动物种类的捕食速率，然后利用已知的食草动物种群密度，计算出实地状况下的群落捕食速率。
2. In the periods of peak zooplankton abundance，that is，in the late spring and in the summer， Haney recorded maximum daily community grazing rates，for nutrient-poor lakes and bog lakes，respectively，of 6.6 percent and 114 percent of daily phytoplankton production.
在浮游动物数量激增的高峰期，亦即在春季后期以及夏季，哈尼记录了最大程度上的每日群落食草比率，对于营养物不充足的湖和沼泽湖而言，分别为每日浮游植物繁殖量的6.6%和114%.
3. The hydrologic cycle，a major topic in this science，is the complete cycle of phenomena through which water passes，beginning as atmospheric water vapor，passing into liquid and solid form as precipitation，thence along and into the ground surface，and finally again returning to the form of atmospheric water vapor by means of evaporation and transpiration.
水文循环(hydrologic cycle)，作为该学科中的一个主要课题，指的是水所经过的诸现象的整个循环过程，开始时是作为大气中的水蒸气，转而作为雨、雪、露、雹一类的降水量经过液体和固体形态，由此而沿着地层表面分布或进入地层表面，最终通过蒸发和散发作用再度回复到大气水蒸气的形态。
4. Only when a system possesses natural or artificial boundaries that associate the water within it the hydrologic cycle may the entire system properly be termed hydrogeologic.
只有当一个系统拥有自然的或人工形成的边界来把边界中的水与水文循环联系起来的时候，才有可能把整个的系统恰当的成为与水文地质学有关。
5. The historian Frederick J. Turner wrote in the 1890's that the agrarian discontent that had been developing steadily in the United States since about 1870 had been precipitated by the closing of the internal frontier——that is，the depletion of available new land needed for further expansion of the American farming system.
史学家弗雷德里克.杰.特纳(Frederick J.Turner)于十九世纪九十年代著述道，美国约自18世纪70年代以来一直在持续不断发展的农民不满，由于国内边远地区(internal frontier)的封闭而更趋加剧——亦即是说，美国农业系统进一步扩展所必需的可资利用的新土地几近耗竭。
6. More probable is bird transport，either externally，by accidental attachment of the seeds to feathers，or internally，by the swallowing of fruit and subsequent excretion of the seeds.
更有可能的是鸟类运输：或者是通过外部途径，即由于种籽偶然粘附在羽毛上;或者是通过内部方式，即由于鸟类吞食果子并随后将种籽排泄出来。
7. A long-held view of the history of English colonies that became the United States has been that England's policy toward these colonies before 1763 was dictated by commercial interests and that a change to a more imperial policy , dominated by expansionist militarist objectives , generated the tensions that ultimately led to the American Revolution .
一个对于后来成了美国的英国殖民地的历史的长久以来的观点，认为英国在1763年以前对于这些殖民地的政策被经济利益所支配，而且认为一种向着更大程度帝国制度的政策上的转变——为扩张主义的军事目标所左右——产生了最终导致美国革命的紧张气氛。
8. It is not known how rare this resemblance is，or whether it is most often seen in inclusions of silicates such as garnet，whose crystallography is generally somewhat similar to that of diamond; but when present，the resemblance is regarded as compelling evidence that the diamonds and inclusions are truly cogenetic.
现在尚不知这种类似稀少到何种地步，也不知道是否它最常见于象石榴石一类的硅酸盐内含物中，而这类物质的晶体结构普遍地在某种程度上类似于金刚石的晶体结构。但一旦存在，这种类似就被视作极有说服力的证据，证明金刚石与内含物确是同源的。
9. Even the "radical" critiques of this mainstream research model，such as the critique developed in Divided Society，attach the issue of ethnic assimilation too mechanically to factors of economic and social mobility and are thus unable to illuminate the cultural subordination of Puerto Ricans as a colonial minority.
即使是对这一主流研究模型的"激进"批评，诸如《分裂的社会》(Divided Society)一书中所提出的那种批判，亦将少数民族同化问题过分机构地与经济和社会移动性的因素联系起来，因此无从阐明波多黎各人作为一个殖民地少数民族的文化从属关系。
10. They are called virtual particles in order to distinguish them from real particles，whose lifetimes are not constrained in the same way，and which can be detected.
它们被称为"虚粒子"(virtual particle)，以便与实粒子(real particle)区分开来，而实粒子则不会以这种方式受到制约，并且其存在可得以测定。
