I'd say the spinal cord has been transected, that it is permanently damaged.

我认为他的脊髓已横断，而且是永久性的损伤。

Every indication told me that the spine was transected, which would have been incurable.

我从种种迹象判断脊柱已被横切，而这是不可治愈的。

But this time, you would use random sampling instead of a transect method we saw before.

但这一次，你将使用随机抽样而不是我们之前看到的带状统计法。

At regular intervals along a pile transect, we place the quadrants down and count the percentage cover of each different species found.

每隔一段时间，我们沿着一堆样带放置象限，并计算所发现的每种不同物种的覆盖百分比。

From this video, you should now know that ecologists are interested in the distribution of organisms within habitats and the use of transects and quadrants, and other sampling methods to collect quantitative data.

从这个视频中，你现在应该知道生态学家对栖息地内生物的分布、带状统计法和象限的使用以及其他采样方法来收集定量数据感兴趣。
