ENGADGET: Alt-week 8.11.12: Robo-billies, quasicrystals and radioactive art

a time in the past when the temperature was very cold and glaciers covered large parts of the earth

any period of time during which a large part of the earth's surface was covered with ice, due to the advance of glaciers, as in the late Carboniferous period, and during most of the Pleistocene glaciation

冰期
In this region, because there is abundant precipitation for glacier development, glaciers are sensitive to temperature changes. Consequently, glacial extent changes most dramatically during the alternation of glacial and interglacial periods, such as the last glacial period.
是我國海洋性冰川發(fā)育的主要地區(qū)之一，其在水分周轉(zhuǎn)中周期短，強(qiáng)度大，變化幅度也較大，對(duì)氣候波動(dòng)的響應(yīng)敏感，因此在冰期—間冰期旋回中雪線就會(huì)出現(xiàn)大范圍的波動(dòng)。

Polyploidization failed to contribute significantly to the expansion of its geographic range. The geographic distribution of diploids and polyploids in G. pentaphyllum may be associated with the past ecological environments of different areas,especially during the glacial period.
絞股藍(lán)的多倍化并沒有顯著擴(kuò)大該種的分布范圍,其二倍體與多倍體的地理分布差異可能反映了不同地區(qū)歷史上的生態(tài)環(huán)境差異,特別是冰期時(shí)不同地區(qū)的生態(tài)環(huán)境。
