some will no doubt flourish, but if the trend continues, as it will for at least some decades, clams, mussels, conches and all creatures that grow shells made of calcium carbonate will struggle.
某些生物无疑会繁盛,但是如果这一趋势继续下去,当它至少持续几十年后,蛤、贻贝、海螺和所有生有碳酸钙外壳的生物将生存困难。
the corals familiar to most of us are colonies of small polyps that build calcium carbonate branches.
我们所熟知的珊瑚都是由群集的微小水螅分泌的分枝状碳酸钙外骨骼。
that is bad because many marine creatures rely on shells made of calcium carbonate to protect themselves.
这是相当糟糕的,因为很多海洋生物生活在钙质碳酸盐的贝壳里以保护自己。
rising carbon dioxide levels acidify the ocean, which has a particularly devastating effect on organisms that have calcium carbonate shells, like foraminifera.
二氧化碳含量上升致使海洋酸化,对像有孔虫这样有碳酸钙外壳的生物体所产生的影响尤为致命。
abalone seashells are made up mostly of calcium carbonate but because of how abalones mix that soft material with proteins at nanoscale sizes, the shells form a nearly unbreakable armor.
鲍鱼贝主要由碳酸钙构成,但由于鲍鱼将柔软的材料与蛋白质融合,其精细程度处于纳米级,形成的贝壳成为了牢不可破的保护层。
the reaction produces a calcium carbonate seal, restoring the slab to its normal load-bearing capacity.
这种反应会产生一种碳酸钙的印迹,并将路面的负荷能力恢复至正常。
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.
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。
susceptibility to acid depends in part on the type of calcium carbonate the animal makes, the researchers found.
研究人员发现,对酸的敏感性在某种程度上取决于动物所产生的碳酸钙类型。
exotic and colorful, coral reefs aren「t lifeless rocks; they are made up of living creatures that excrete a hard calcium carbonate exoskeleton.
形状奇特,颜色丰富,珊瑚礁并不是一般意义上的石头,而是一种生物分泌钙化碳酸盐的坚硬外骨骼。
some minerals, such as calcium carbonate in seashells, glow blue, as does a shovel handle in the picture above.
有些矿物,如海贝中的碳酸钙,会闪着蓝光,就如同上图中的铁锹的把手。
under uv light, clean sand appears purple or black. some minerals, such as calcium carbonate in seashells, glow blue, as does a shovel handle in the picture above.
紫外线照射下,干凈的沙子呈紫色或黑色。有些矿物,如海贝中的碳酸钙,会闪着蓝光,就如同上图中的铁锹的把手。
meanwhile, calcium ions in the cement also absorb moisture and carbon dioxide, forming calcium carbonate -- the material found in seashells.
同时,水泥中的钙离子也会吸收水分和二氧化碳,形成碳酸钙——碳酸钙是贝壳的主要成分。
most water contains some carbon dioxide, making it a weak acid that can eat away at the calcium carbonate in limestone.
大多数水含有一些二氧化碳,使得水显弱酸性,能够侵蚀石灰巖中的碳酸钙。
these calcium carbonate towers, called tufas, formed underwater in california」s mono lake.
这些叫做石灰华的碳酸钙塔是在加州莫诺湖的水下形成的。
coral reefs are formed by deposits of calcium carbonate left by successive generations of tiny polyps which feed off plankton.
珊瑚礁是由历代以浮游生物为食的小水螅所遗留下来的碳酸钙沉积物而形成的。
many invertebrates have shells of calcium carbonate that bear evidence of the physical conditions in which they formed.
许多无脊椎动物的碳酸钙贝壳中可以找到其形成时自然条件的证据。
in reefs, the structure is big lumps of calcium carbonate on which things grow and around which they graze and hunt.
对于珊瑚礁而言,结构就是大块的碳酸钙礁石,一切都发生在礁石之上或周围。
