And those leaves also started secreting acid fluids that could dissolve any incoming apatite, assisting phosphorus's absorption.

这些叶子也开始泌酸性液体，可以溶解任何进入石，帮助吸收。

This mineral is mostly hydroxyapatite — tough stuff that's rich in calcium and phosphate.

这种矿物大部是羟石——它们非常坚硬而且富含钙和酸盐。

The lamellae have an organic part, which is mostly collagen, and an inorganic part called hydroxyapatite, which is mostly calcium phosphate.

这些薄片有机部主是胶原蛋白，而无机部称为羟石，其主是酸钙。

Anyways, about 99% of that calcium is in our bones in the form of calcium phosphate, also called hydroxyapatite.

而大约99%钙在我们骨骼中以酸钙形式存在，也被叫做羟基石。

All of this from body parts that are about 70% mineral, made of an inorganic material called hydroxyapatite that is stiff when compressed, combined with flexible protein called collagen to keep you from shattering.

所有这些身体部位大约 70% 是矿物，由一种叫做羟基石无机材料制，这种材料在压缩时是坚硬，与一种叫做胶原蛋白柔性蛋白结合在一起，可以防止你粉碎。

In the body, about 85% of the phosphate is stored in the bones, where it combines with calcium to make a tough compound called hydroxyapatite which is the stuff that makes bones hard.

在人体中，约85%酸盐储存在骨骼中，它在骨骼与钙结合形一种叫做羟基石坚硬化合物，这是为什么骨头比较坚硬原因。

But others pointed out that the fossils were made from a mineral called hydroxylapatite.

但其他人指出，这些化石是由一种叫做羟基石矿物形。

This mineral is mostly hydroxyapatite – tough stuff that's rich in calcium and phosphate.

这种矿物主是羟基石 - - 一种富含钙和酸盐坚硬物。
