查询词典 dominant

However remarkable impacts were observed in the plantation in terms of community physiognomy,community structure,species composition,species richness,and biomass accumulation.1 Planting trees made community structure simple.Betula alnoidis plantation had three layers including a dominant arbor layer,a complex and well developed shrub layer and a poorly developed vine layer.The arbor layer contained few species and had a single layer.The mountain rain forest had 4 layers including the dominant arbor layer,shrub layer,grass layer and vine layer.The vine layer was well developed and very rich in species composition,and the arbor layer contained as many as 38 species that could be grouped into 3 layers.2 Sequenced by the important value,main species for the plantation and the nature forest were totally different,and the plantation had one dominant species while the nature forest contained many dominant species.3 Planting trees changed the community physiognomy.

但是人工种植西南桦林对群落的季相外貌、群落的结构、物种组成、物种丰富度以及生物量等方面有较大的影响。1人工造林使得群落结构简化，西南桦人工林的层次结构有3层，以乔木层占优势，并且有种类多而发达的灌木层，同时，藤本植物欠发达，但是乔木层树种单一，明显仅有一层；山地雨林的层次结构有4层，以乔木层占优势，还有灌木层、草本层和藤本植物，藤本植物种类多，十分发达；乔木层树种丰富，可达38种，乔木层还可分为3层。2人工造林较大程度地改变了群落的物种组成，根据重要值的大小排列，人工林和天然林的主要物种组成已经完全不同；并且人工林单优树种明显，而天然林就含有较多的优势树种。3人工造林改变了群落的外貌。

This research is to discuss the different effects dominant legs and non-dominant legs cause on static balance, ground reaction and speed by the following seven evaluation methods of dominant legs: ball-kick, step-up, hop-for-distance, step-forward, balance-recovery, fencing in epee, and individual preference.

摘要本研究的目的在利用七种惯用脚评定方式(踢球、登阶、跳远、往前踩步、恢复平衡、锐剑防卫和个人喜好等七种)，分别探讨惯用脚和非惯用脚在静态平衡能力、对地反作用力和速度之差异性，并发现六种评定方式的信度和七种惯用脚评定方式相互之间的差异性。

This paper starts on evocable disputes of price adjustment of commutation ticket of Nanjing public transportation. Then using the basic model of new economics of regulation, it analyzes the behavior selection of the government, regulatory agencies and the firms under regulation respectively in pricing game for public goods , and indicates that the dominant strategy of the dominant firms in the supplying public goods is to adjust the price instead of controlling cost, while other firms' dominant strategy is to follow.

本文以南京市公交月票的价格调整引起的争论为起点，根据新管制经济学的基本模型，分析在信息不对称的条件下政府、管制机构和被管制企业在公用产品价格博弈中的行为选择。

A clone from each genotype was randomly selected as representative for sequencing. The obtained 16S rDNA gene sequences had a similarity of 87%-100% with those in the GenBank (www. ncbi. nlm. nih. gov), and more than half of them had a similarity lower than 97%, being of new species. Based on phylogenetic analysis, the bacteria in the two soils were classified into 10 groups, with 5 groups in common. The dominant bacterial groups in the two soils differed obviously. In primeval forest soil, the dominant group was Proteobacteria, which had 39 genotypes, occupying 58.0% of all the clones; while in the soil of degraded ecosystem the dominant groups were Acidobacteria and Proteobacteria, which had 19 and 15 genotypes occupying 32.5% and 30.5% of all the clones, respectively. In the soil of degraded ecosystem, Proteobacteria group decreased while Acidobacteria group increased markedly, compared with those in primeval forest soil.

从每种基因型中随机选择一个克隆子作为代表进行测序分析，所有序列与GenBank数据库中序列的同源性为87%~100%，且两样地中均有超过一半的基因型序列与数据库中已知序列同源性低于97%，属于分类在"种"地位上的新发现细菌；通过系统发育研究将两样地的细菌分为10大类群，两样地共同拥有5大类群，但两样地的细菌优势类群明显不同，原生土壤为Proteobacteria，含39种基因型，占总克隆子数的58.0%，退化生态系统土壤为Acidobacteria和Proteobacteria，分别含19种和15种基因型，占总克隆子数的32.5%和30.5%；与原生土壤细菌类群相比，退化生态系统土壤Proteobacteria类群明显减少，Acidobacteria类群明显增加。

In encounters paired between unfamiliar males and males, there is great difference between dominant male and subordinate one. The dominants approached, attacked and chased the subordinate more often and spent significantly longer time.The subordinates defend or escaped the dominant more often and spent significantly longer time, but there is no significant difference on nonsocial behaviors between the dominant individual and the subordinate one.Frequencies of aggressive and social investigating behaviors are positively correlated with body mass.

结果发现，当陌生的两只雄鼠相遇时，优势雄鼠和从属雄鼠间的社会行为有明显的区别，优势鼠接近、攻击、追赶对方的频次和持续时间明显的多于从属鼠，而从属鼠逃离和防御行为多于优势鼠；优势鼠的体重明显的大于从属鼠，而且攻击行为和社会探究行为的频次与体重呈正相关，非社会行为无明显的差别。

The dominant point detection ability of the proposed planar contour dominant point detection method is tested by an emulational planar contour which includes all kinds of dominant points.

采用包含各种类型特征点的仿真平面轮廓，对本文提出的平面轮廓特征点检测方法的特征点检测能力进行了测试。

In addition, the community types, structure and ecological relationships were also analyzed in this thesis.x~2-test and Spearman's rank correlation coefficient were used toanalyze interspecific relationships of 8 dominant tree species, 13 dominant shrubs and 20 dominant herbs respectively.

采用χ~2检验和Spearman秩相关系数检验研究了小叶鹅耳枥群落的种间关系，分别测定了8种乔木、13种灌木和20种草本在群落中的种间联结性和相关性。

A low level of disturbance can not bring the obvious changes to the subaerial algae in community interior, intermediate disturbance can increase the species quatities of subaerial algae, but can not change the dominant species of algae community, while the serious or repeated disturbance may alter both the component of species and the dominant species, that is species quatities decrease, and dominant species change.

局部小范围的干扰或轻度干扰不会对群落内部亚生藻类的种类组成产生明显影响；中度干扰可使群落内部的亚气生藻类的种类明显增加，但藻类群落的优势种不会改变；而重度干扰下，植物群落内的亚气生藻类的种类组成及优势种均会发生重大变化，种类数量减少，优势种改变。

Great. What repertoire did you see?

太棒了。你看的是什么剧目？
