一个名称、命名举动或著作物：在命名法上的地位(亦即其适用性或其他方面，就一名称而言，其拼法所指示的命名分类单元的模式确定，以及相对於其他名称的优先地位)。

The highest ranked category employed in the taxonomic hierarchy.(Previous editions of the Code referred to a single taxon "Animalia", not widely accepted today, at the rank of kingdom).

应用於分类学层系中层级最高的一级(本规约以前的版本中是指一个单一分类单元，即动物界「Animalia」，属於界，但现今尚未广被接受)。

Some taxon-selective primers that were intended to be specific to fungi and basidiomycetes respectively have been designed and tested to characterize fungal symbionts by amplification of specific sequences in the nuclear ribosomal unit.

The combination Caiman yacare first appears in Schmidt (1928), who points out that, although many early authors did not recognize this caiman as distinct from sclerops (=crocodilus), it is clearly the taxon referred to by Daudin in his description of Crocodilus yacare.

结合凯门鳄亚卡雷第一次出现在施密特（ 1928年），谁指出，虽然许多早期的作者没有认识到这一点，凯门鳄有别于sclerops ，它显然是类群所提到的在他的描述Daudin的鳄亚卡雷。

Medem (1981, 1983) and others have argued that because the name crocodilus was misapplied to all crocodilians, Schneider's original specific epithet, sclerops (1801), should be applied to this taxon .

梅德姆（ 1981年， 1983年）和其他人认为，由于名称误用鳄是所有鳄鱼，施耐德的原始具体修饰语， sclerops （ 1801年），应适用于这一类群。

Result: Chemical constituents of this taxon included several natural groups: benzylisoquinoline alkaloid, ranunculin, triterpenoid glycoside and diterpene alkaloid etc.

结果：发现本科的化学成分可以划分为几大类型：苄基异喹啉类生物碱，毛茛苷类，三萜皂苷，二萜生物碱等。

It indicates that decrease in taxon number could be compensated with increasing density of some taxa. Therefore, loss of some taxa in a faunal community may lead to a constant or higher diversity ranges. Due to this reason, we do not suggest that DG index could be used as a diversity measurement.

另外，DG指数与类群数(r=0.648， P=0.000)和类群密度(r=0.487， P=0.000)呈明显的正相关，类群数的下降可以通过部分类群密度的上升而获得补偿，群落的类群丢失后却可以获得一个不变的甚至更高的多样性值。

By means of GC-MS-Ms method, the multiple series of age-related and taxon specific biomarkers are tested in source rocks and oil samples from Liaohe oilfield and Tarim basin, which are hard to be detected by conventional GC-MS method. They are steranes, methylsteranes, Tricyclic and tetracyclic diterpanes, methyl hopanoid alkanes and hexacyclic hopanoid alkanes, etc.

利用色谱－质普－质普方法在辽河与塔里木盆地源岩和原油样品中，检测出了多个系列时代相关及特定种属生物标志物，包括：降胆甾烷系列、甲基甾烷及甲藻甾烷系列、三环二萜烷及四环二萜烷系列、六环蒮烷及甲基藿烷系列等等，这些化合物很难用常规GC-MS形方法检测到。

A taxon or assemblage of taxa; e.g. the taxonomic group Insecta consists of all insects and the taxa in which they are classified.

一个分类单元或一组分类单元；例如昆虫纲这个分类群包含全部昆虫以及被列入的各个分类单元。

According to the clear water experiment, aeration performance of the new equipment is good with high total oxygen transfer coefficient and oxygen utilization ratio.

曝气设备的动力效率在叶轮转速为120rpm～150rpm时取得最大值，此时氧利用率和充氧能力也具有较高值。

The environmental stability of that world - including its crushing pressures and icy darkness - means that some of its most famous inhabitants have survived for eons as evolutionary throwbacks, their bodies undergoing little change.

稳定的海底环境─包括能把人压扁的压力和冰冷的黑暗─意谓海底某些最知名的栖居生物已以演化返祖的样态活了万世，形体几无变化。
