it's a polymer that can

这是一种在光照下
be polymerized when you shine light on it.

就能聚合的高分子材料
It's not too dissimilar from the materials

和牙医用来补牙的材料
that's dentists use now to fill cavities.

其实没有什么本质区别
If you had a cavity filled recently

如果你最近有补牙
they put some sort of a material into the cavity

牙医会在蛀洞里填充一种材料
and then they shine a light on it.

然后用光照
They put on the goggles and

他们带上护目镜
they cover up your face and they shine a light on it.

盖住你的脸然后施加光照
The polymer that they put into the cavity polymerizes

这样他们植入蛀洞的材料在光照下聚合
and forms a hard surface.

形成一个坚实的表面
Here, they put the polymer all around the acetabular cup,

而在本例中他们在髋臼周围涂上这种材料
