As the fly passes and drifts downstream, lower the rod tip and feed line to the drift. 当饰带毛勾漂流到下游时,降低竿尖和增放飞蝇线使饰带毛勾继续漂流。
Because the average users use the net mainly to download data, ADSL proposes the way of making the rate of downstream bigger than the upstream according to the realistic situation. As a result Asymmetric Digital Subscriber Line came out. 由于普通用户上网时主要是下载数据,所以ADSL根据这种现实情况提出下行速率大于上行速率的方式来提供用户上网,此即不对称数字用户线的由来。
The floodgate may be regarded as a series system with four main failures modes including slip along the foundation, compression failure of the floodgate toe in the downstream line, tension crack of the floodgate heel in the upper stream and non-uniform stress distributions. 软基上的水闸可看成由4种主要失效模式(沿闸基面的滑动、下游闸趾压坏、上游闸踵拉裂和上下游应力不均匀)所组成的串联体系。
The results show that the four failure modes were ranked from highest to lowest effect: slip along the foundation, non-uniform distributions of stress, tension crack of the floodgate heel in the upper stream and compression failure of the floodgate toe in the downstream line. 由计算结果看出,水闸闸室沿闸基面滑动为水闸的最主要失效模式,上下游应力不均匀、上游闸踵拉裂、下游闸趾压坏为次要失效模式。
The saturation-based congestion evaluation method is proposed in this paper. We install a detector downstream of a stop line which can be measured. With the cost of data collection reduced, this method has practical value. 本文研究了基于饱和度的拥挤评价方法,利用安装在停车线下游的单个检测器获取车辆占用检测器时间,计算饱和度,降低收集数据的成本,具有实际应用价值。
