色维度

The spatial,temporal and two-dimensional niche breadths and niche overlaps of Hyalopterus amygda/i, Myzus persicae and their main natural enemies were studied in this paper. The results showed that the synchronism and sympatry of the pests and their natural enemies Harmonia axyridis, Propylaea japonica and Chrysopa septempunctata were both higher, which provided a foundation for protecting and using natural enemies to control the two pests.Key words: Hyalopterus amygdali; Myzus persicae; Natural enemies; Ecological niche

为了保护利用天敌，充分发挥天敌对害虫的自然控制作用，作者对桃粉蚜、桃蚜及其主要大敌在时间维度、空间维度和时—空二维生态位宽度和生态位重叠进行了研究，评价了4种主要大敌异色瓢虫、龟纹瓢虫、大草岭、蜘蛛对这2种害虫在时间和空间上的跟随作用和控制效果，为桃园桃粉蚜、桃蚜两种害虫的生态控制提供理论依据。

There are already technicolor, supersymmetery, extra dimension etc.

在这方面，已经有人工色、超对称、额外空间维度等等，它们从建立新的数学模型入手，来进行探索。

As an analogy, we might say that our trichromatic color vision can be represented in a triangle, whereas their tetrachromatic color vision requires an additional dimension, giving a tetrahedron or triangular pyramid.

让我们做个类比，如果用一个三角形来代表人类的三色色觉，那麽鸟类的四色色觉就需要多一个空间维度来代表，得到的就是四面体或三角锥体。

Among the enemy population, intra-species competition is fiercest for Coccinella septempunctata and weakest for E. plagiator. In terms of time, competition between P. japonica and C. septempunctata or Leis axyridis is relatively fierce. However, that between E. plagiator and P. japonica, C. septempunctata or L. axyridis is weaker.

在天敌种群中以七星瓢虫种内竞争最为激烈，麦蚜茧蜂的种内竞争最为缓和；龟纹瓢虫分别与七星瓢虫和异色瓢虫在时间维度上的竞争较为激烈，而麦蚜茧蜂分别与龟纹瓢虫、七星瓢虫和异色瓢虫的竞争比较缓和。

Singer Leona Lewis and former Led Zeppelin guitarist Jimmy Page emerged as the bus transformed into a grass-covered carnival float, and the pair combined for a rendition of "Whole Lotta Love".
