Wind and rain continued to erode the rocks of Dinosaur Park, and expose new dinosaur bones every year.

风雨不断侵蚀着恐龙园的岩石，每年都会露出新的恐龙骨骼。

Every 10 years, you've got a new skeleton, a special team of cells breaks down old bone, and another builds new bone.

每10年，你会有一个全新的骨骼，有一群特殊的细胞负责把老骨头分解，也有另外一群细胞会建造新的骨头。

Then the blood carries the digested food with it all over the body, and everywhere it helps to form new bones, and muscles, and nerves.

然后, 血液带着这些经过消化的食物流经全身, 它们在各个地方促进新的骨头、肌肉与神经的生长。

The artificial vertebra has a honeycomb structure, which allows the new bone tissue to grow into it, and surgical screws are not needed to attach it.

人工脊椎的蜂窝状结构允许新骨组织生长, 而且不需要手术螺钉。

This is caused by increased bone resorption, which is a process that breaks bones down, eventually fast enough that it outweighs the rate of new bone growth.

这是由骨骼逐渐溶蚀所引起，整个过程会造成骨折，最终则因速度太快，远超过骨骼的生长率。

Bone is slowly reabsorbed by our body, but the strain of moving and lifting our weight stimulates the growth of new bone material to replace it.

骨骼会慢慢被我们的身体重新吸收，但是移动和举重的压力会刺激新骨骼材料的生长来替代它。

This ends up causing new bone formation and the medullary cavites of the skull can expand outward, which causes enlarged cheeks and a " hair-on-end" appearance on skull x-ray.

这最终导致新骨形成，及颅骨髓腔可能向外扩展，在头颅X线上表现为增大的脸颊以及“竖发征”。

In the autumn of 2013, Berger was hoping to find new bones — well, new very old bones, in what's known as the Cradle of Humankind World Heritage Site, in South Africa.

2013 年秋天，伯格希望在南非被称为“人类摇篮”的世界遗产地发现新的骨头——就是，非常古老的新骨头。

So, osteoporosis is when there's a higher breakdown of bone in comparison to the formation of new bone which results in porous bones, meaning a decrease in bone density to the point of potential fracture.

所以，Osteoporosis骨质疏松，意味着相比新骨的生成，骨组织被分解的程度更高，导致了多孔样的骨质，这会造成骨密度下降，从而增加骨折风险。
