1·You see, the denser the medium, the faster sound travels.

如你所见，介质越密集，声音传播就越快。

2·Competition is usually the more severe the denser the population.

通常是人口越密集，竞争越激烈

3·Late growth wood is denser, less porous.

晚生木材密度大，没有那么多孔。

4·The denser layers are generally darker than the less dense layers.

较紧密的木层比较疏松的木层颜色更深。

5·He travelled on and on; but the farther he went, the denser the wood became, apparently.

他走啊走；但他走得越远，树林就显得越密。

6·As the air space around them is lessened by compaction and melting, the grains become denser.

由于它们周围的空气被压缩、融化而逐渐减少，颗粒变得更加密集了。

7·Silicates such as mineral quartz drifted downward and mixed with denser materials as they reached Earth's core.

石英等硅酸盐向下漂移，在到达地核时与密度更大的物质混合。

8·All are slowly moving because the plates float on a denser semi-liquid mantle, the layer between the crust and Earth's core.

所有板块都在缓慢移动，因为它们漂浮在密度更大的半液态地幔上，也就是地壳和地核之间的那一层。

9·All are slowly moving because the plates float on a denser sem-iliquid mantle, the layer between the crust and Earth's core.

所有板块都在缓慢移动，因为它们漂浮在密度更大的半流体地幔上，也就是地壳和地核之间的那一层。

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

海洋板块是由密度更大、更重的岩石构成的，所以它开始下沉到大陆板块之下，到地幔之中。
