1·Much of the soil is usually still frozen during peak run-off.

大部分的土壤在径流高峰期仍然是冻结的。

2·What about run-off in the spring, when the snow finally melts?

到了春天，雪最终融化的时候，水流是怎么样的？

3·Once this pan formed, further run-off collected, and formed a lake.

一旦这个池子形成，径流就会进一步汇集，从而形成一个湖泊。

4·Agricultural run-off and pollution from power plants are adding extra nitrogen to many bogs in North America.

农业排水和来自发电厂的污染给北美的许多沼泽增加了额外的氮。

5·The nutrients are deep down in the active layer anyway, not high up near the surface, which is the part of the active layer most affected by run-off.

不管怎样，营养物质存在于活性层深处而不是在表层附近，活性层受径流影响最大的地方。

6·Natural soil fertility is dropping in many areas because of continuous industrial fertiliser and pesticide use, while the growth of algae is increasing in lakes because of the fertiliser run-off.

在很多地区，由于工业化肥和农药的持续使用，导致自然土壤的肥力正在下降，然而化肥的流入却导致湖泊中藻类生长得越来越快。

7·Her immediate aim is to make it to the run-off ballot.

她现阶段的目标是要挤进第二回合投票。

8·New buildings would also have to meet run-off regulations.

同时，还将保证新的建筑达到径流管理规定。

9·They also welcomed the decision to cancel the run-off election.

他们也对阿富汗取消决选表示欢迎。

10·Ms Moratti still has a chance to revive her fortunes in the run-off.

莫拉蒂女士仍然有机会在决选中收复失地。

决赛

1·Indeed, both Ms Manigat and Mr Martelly had called for a do-over election—until it appeared they would advance to the run-off.

事实上，直到有消息说他俩提前进入决赛前，马女士和马先生本来都是要求重新进行选举的。

流量

1·Based on generalized run-off triangle, we introduce multiplicative model and its marginal-sum estimation in chapter 2. We get that the marginal-sum estimation is the chain ladder estimation.

基于一般的流量三角形，我们在第二章中提出了乘法模型及边际和估计，并证明了在该模型下，参数的边际和估计就是链梯法估计。
