珊瑚骨骼

造礁珊瑚骨骼δ~（13）C及其反映的环境信息研究概况

General Situation of the Study on Reef Coral δ ~ ( 13 ) C and the Related Environment information

珊瑚骨骼δ~（13）C与δ~（18）O有正相关、负相关和无相关3种情况，可以解释相应的环境状况。

The relationship between coral skeletons δ 13C and δ 18O , including positive correlation , inverse correlation and non-correlation , can be used to explain the environmental condition .

此外，比起胶带上的海葵，放在珊瑚骨骼上的海葵所遭受的紫外辐射少四倍，其DNA所受到的破坏少大约七倍。

What 's more , anemones placed on the coral received four times less UV radiation and showed about seven times less damage to their DNA than those placed on the tape .

本文依据珊瑚骨骼生长带X射线成像原理，利用计算机的数字化和影像处理功能，提出了珊瑚骨骼生长带数字影像分析的方法，能获得较传统方法更高分辨率和精度的珊瑚生长信息。

According to the X-ray imaging principle of skeletal band , this paper provides image analyzing methods of coral skeletal band by using digitalization and image procedures of computer . The methods can acquire growth information of coral with higher resolution and precision than conventional methods .

研究小组将海葵分别放在珊瑚骨骼上和白色的管道胶带上。

The team placed the anemones on top of either coral skeletons or white plumbing tape in the lab.

圣诞树虫钻入珊瑚骨骼寻求保护把身体卷成一圈探出用羽毛状的鳃抓取食物碎粒

Christmas tree worms bore into the coral 's skeleton for protection , swirling out and grabbing food particles with their feathery gills .

骨骼钙化作用和虫黄藻光合作用的相互关系还存有争议，珊瑚骨骼钙化机理仍在探索中。

The relationship between skeleton calcification and photosynthesis of zooxanthellae is a controversial question , and the mechanism of calcification is still being explored .

通过采用硼同位素法、铁锰微量元素法和生长特征观测法等方法，研究珊瑚骨骼的化学特征，从而可能揭示过去赤潮发生的规律。

We can analyze the geochemical changes in coral skeletons such as boron isotope and trace elements like iron and manganese and probe into characteristics of corals so as to investigate the historical red tides .

结果表明，珊瑚骨骼内重金属平均质量分数顺序为：Cu>Zn>Pb>Cd>Cr，重金属的富集系数顺序为：Cd>Pb>Cu>Cr>Zn。

The average contents of heavy metals in coral skeleton follow : Cu > Zn > Pb > Cd > Cr , and the enrichment coefficients of heavy metals follow : Cd > Pb > Cu > Cr > Zn .

而死亡的珊瑚礁的骨骼大片大片的被海藻覆盖。

and big patches of dead skeleton that would get overgrown by algae .

珊瑚其实是珊瑚虫的外骨骼。

Coral is actually the exoskeletons of coral polyps .

过去的研究发现，构成珊瑚礁的碳酸钙质珊瑚外骨骼在紫外线的照射下会发出荧光，这表明这些外骨骼吸收紫外线。

Past studies have found that the calcium carbonate exoskeletons of corals that make up reefs fluoresce under ultraviolet light , suggesting that they absorb UV rays .

造礁珊瑚是研究热带海洋环境变化的极好材料，珊瑚骨骼δ~（18）O分析是提示其所记录的环境信息的重要手段。

Reef coral has proved to be an excellent material with which to research into the tropical ocean environment , and its skeleton δ 18O is an important tracer for analyzing the recorded environmental information .
