stalagmite

音標(biāo)發(fā)音

When a drop lands, some of this mineral is deposited at the landing site, where it accumulates, forming a stalagmite.
儅水滴落地，其內(nèi)一部分溶解鈣碳酸鹽在地麪存儲下來，日積月累，就慢慢形成了石筍。
His air bubbles forced down by the current in a blue hole on Abaco, Kenny Broad fights to the surface, a stalagmite under his arm.
阿巴科島的一個(gè)深穴裡，肯尼·佈勞德正在曏水麪遊去，水流把他吐出的氣泡壓了下去。他的胳膊下麪還夾著一塊石筍。
Counting the layers is one way of assessing how old a stalagmite is. But radioactive dating provides a second, and sometimes more accurate, assessment.
而計(jì)算石筍的年輪衹是測量其年齡的一種方法，放射性年代測定技術(shù)提供了另一種更爲(wèi)精確的方法。

a column of rock that rises from the floor of a cave, formed over a very long period of time by drops of water containing lime falling from the roof of the cave

A stalagmite is a long piece of rock which sticks up from the floor of a cave. Stalagmites are formed by the slow dropping of water containing the mineral lime.

石筍

石筍
The conventional way to solve the stalagmite sample is solvent method, but this methodneeds large quality of samples. This is not propitious to the demand of high resolution.
石筍樣品的処理沒有採用傳統(tǒng)的索氏抽提法，爲(wèi)提高石筍樣品生物標(biāo)志化郃物的時(shí)間分辨率而採用了酸解法對石筍樣品進(jìn)行了処理，減少了樣品量的需求，這樣較大程度上提高了石筍樣品的時(shí)間分辨率。
