denser

because it is a very heavy substance, 1.7 times denser than lead, it is highly valued by the military for its ability to punch through armored vehicles and buildings.

因为这是一种非常重的物质（比铅的密度大1.7倍），其穿透装甲车辆和建筑物的能力备受军方重视。

Denser and less defects films can be prepared using a 99.99% alumina source. The resistivity and dielectric loss can be reached to 1012 Ocm and 103, respectively.

最终得出：由99.99%的三氧化二铝原料制备出的薄膜致密性好、缺陷少，其绝缘电阻率和损耗分别可达1012O·cm和103量级；

So the... um... the oceanic plate is made of denser and heavier rock, so it begins to sink down under the continental plate and into the mantle.

海洋板块由更紧密，更重的石块构成，所以海洋板块开始下沉到大陆板块之下，沉到地幔表面。
