On the basis of forefathers study, the interaction of the shock waves of torrent, and that of rarefaction to shock wave have been discussed in detail in the useof the concept of the curve.

在前人研究的基础上，通过引入曲线的概念，分别对急流冲击波的相互作用，稀疏波与冲击波的相互作用进行了比较详细地讨论。

In the situation of shock wave, the interaction caused by the situation of one shock wave catching up with another is qualitatively analyzed with the result of the wave form: reflection rarefaction and incidence shock wave.

Twenty-four sites were sampled over three different periods in three rivers of the plateau. At each site, a riffle and a pool were identified, in a stretch of about 100 m, as separate habitat units, and were sampled for fish and physical habitat. A preference index and logistic regression were used to determine the important habitat variables for each species.

分3个时期选择3条河流的24个地点进行取样，每个样点长100 m左右；分急流和回水湾两种生境类型作为独立的栖息地单元取样，据此观察研究对象和物理环境间的关系；用喜好指数和逻辑回归分析每种鱼重要栖息地是否稳定。

About four a-Clock in the Evening, being then within about a League of the Island, I found the Point of the Rocks which occasioned this Disaster, stretching out as is describ'd before to the Southward, and casting off the Current more Southwardly, had of Course made another Eddy to the North, and this I found very strong, but not directly setting the Way my Course lay which was due West, but almost full North.

大约下午四点钟，在离海岛不到三海里的地方，我看到了伸向南方的岬角，这一点我前面也已提到过。正是这堆礁石引发了这次祸端。岬角把急流进一步向南方逼去，同时又分出一股回流向北方流去。这股回流流得很急，一直向正北。这不是我要航行的方向，我的航线是要往西走。
