宽度

Analyses of niche breadths and overlaps of several plant species in three Kobresia communities of an alpine meadow .

三种蒿草群落中若干植物种的生态位宽度与重叠分析。

Their niche breadths were calculated by Levins equation.

根据Levins公式计算了75种藓类植物的生态位宽度。

Pattern of use for these resources was analyzed from three vegetation types by examining species-specific niche breadths, overlaps and partitions of resource utilization as well as population sizes.

对于这些资源利用的格局是通过对存在于三种类型植被中蝗虫种的生态位宽度、资源利用的分化和重叠以及每种蝗虫的种群大小来分析的。

Pieces of material of different breadths.

宽度不一的料子

A 10-mm port is carefully introduced in the midline, one to two finger breadths above the pubic ramus.

小心地将一根直径10mm 的通道引入中线位置，并位于耻骨支上方一至两指的宽度。

In the plant vegetations are mainly communities, the niche breadths vary greatly and the similarity ratios among different plants are very low.

植物群落内生态位宽度悬殊，植物种之间的生态位相似比例很小。

The airbus, perhaps the most advanced subsonic airliner in use, has wings designed so that lift is spread along their breadths.

空客，也许是现使用中最先进的亚音速客机，它们的翼型设计使得升力沿客机的宽度伸展商务。

The niche breadths of same plants vary greatly among different communities and the competitive relations of the plant species in different communities vary depending on the combined actions of the niches of the species, stable landforms and soil conditions, and annual rainfall fluctuations.

同一种植物在不同群落中的生态位宽度变幅较大，不同群落内部植物种竞争关系的差异是由物种的生态位和由相对稳定的地貌、土壤条件以及随年际变动的降水条件共同作用的结果。

In multidimensional space,the niche breadths of these plants tended to expand,whereas theniche overlaps tended to decrease and the niche separations tended toincrease.

在多维生态位空间内，各植物种的生态位宽度有扩大的趋势而相互间的生态位重叠有减小的趋势，生态位分离度有增加的趋势。

Niche breadths of most native populations in natural forest were wider than that of P. armandii forest. Furthermore, competitions among populations were not so strong, and community structure was more stable, because of great niche differentiation in natural forest.

天然林中大多数乡土树种的生态位宽度较之在华山松林中大为增加，但由于长期协同进化，种间生态位分化程度高，种间竞争较缓和，群落具有很高的稳定性。

The split between the two groups can hardly be papered over.

这两个团体间的分歧难以掩饰。

This approach not only encourages a greater number of responses, but minimizes the likelihood of stale groupthink.

这种做法不仅鼓励了更多的反应，而且减少跟风的可能性。
