Within a vertical distance of just a few tens of meters, trees disappear as a life-form and are replaced by low shrubs, herbs, and grasses.

就在几十米的垂直距离内，树木这种生命形式消失了，取而代之的是低矮的灌木、草本植物和小草。

In terms of the total vertical profile exposed and the low elevation, Gale offers attractions similar to Mars' famous Valles Marineris, the largest canyon in the solar system.

从目前所能观察到的整体垂直剖面结构和低海拔的特点来看，盖尔陨坑的科研魅力与太阳系中最大的峡谷——著名的水手峡谷不相上下。

At ground level, such vibrations-akin to low-frequency sound waves-are very small, only about the size of the vertical motions that produce them.

在地表，这种类似于低频声波的振动非常小，只相当于造成它们的垂直振动的幅度。

We expect this vertical integration in the plastics division to ensure a stable and consistent supply of feedstock, hence providing low-cost advantages in the long run.
