But this is a feedback loop — shells that dissolve add more calcium carbonate to the water, making it harder for other shells to dissolve and lowering the " dissolving depth" .

但这是一个反馈循环——贝壳溶解后为海水提供了更多钙离子和碳酸根离子，使他贝壳更难溶解，溶解深度就降低了。

In front of the monastery, there lies a karst cave of immeasurable depth, while behind it, there is a stone tablet. All but the top of the tablet has been buried in calcium carbonate, so that the inscriptions are unreadable now.

Oh, stuff like magnesium salts, and alcohol for keeping the Deltas and Epsilons small and backward; and calcium carbonate for bones, and all that sort of thing.

哦，比如镁盐，比如保持德尔塔和爱扑塞隆们瘦小落后酒精；比如制造骨头碳酸钙和诸如此类东西。

Likewise, osteoblasts are the blast cells of bone tissue, and the matrix they lay down is the nexus of calcium carbonate that forms your bone.

If you dissolve away an egg shell, which is rich in calcium carbonate, with an acid, like vinegar, it maintains its shape.

如果你用醋之类酸溶解富含碳酸钙蛋壳，会保持形状。

Hard corals create the reef by secreting calcium carbonate—or limestone, a type of rock, which gradually builds up into a solid structure.

硬珊瑚通分泌碳酸钙来造礁，或称之为石灰岩，一种岩石类型，逐渐形成固体结构。

Normal concrete is bound with Portland cement, which is made by roasting a mixture that includes limestone (calcium carbonate).
