您要查找的是不是：
- sediment discharge ratio 排沙比
- The design of pipes depends on comparative power requirements to deliver a given sediment discharge. 在设计管道时，必须比较其对于输送一定量的泥沙所需要的功率。
- The runoff discharge has been stable in Datong while sediment discharge has been declining obviously Dyer the past 49 years. 大通站径流量在保持稳定的情势下，输沙量在过去49年中有明显的下降。
- This pressure difference tends to increase following the increase of discharge ratio at first and decreases after a peak value occurred. 分离区内外压强差随交汇角增大而增大，随流量比的增大先增大后减小。
- In flood season, sediment discharge of reservoir retrogressive erosion is proportional to discharge and water surface slope before the dam, its rang is between Guduo and Dayudu. 水库汛期溯源冲刷输沙率与流量和坝前比降成正比，溯源冲刷范围一般在和大禹渡之间；
- There are lots of factors which influence the evolvement law of sediment discharge, and it is very difficult to be known and gained, it results in low precision of simulation and forecast. 摘要影响输沙量演变规律的前期因素比较多，且难于确定和提取，这就造成对输沙量的拟合和预测精度较低。
- The marsh surface supplied water quantity accounts for 33% of the ebb water quantity in the creek,resulting in 20% of the ebb suspended sediment discharge in the creek during the ebb. This is a basic influence on the time asymmetry. 滩面归槽水占潮沟落潮输水量的33%25;由此造成的悬沙输运量占潮沟落潮悬沙输运量的20%25;这是导致潮沟涨落潮输水输沙不对称的主要因素.
- Migration characteristics of oil and gas is summarized as below: 1)Hydrocarbon discharge ratio of 2 sets of mature source rocks (K_1ba and K_1bt~1) in the Lower Cretaceous is about 32%-72%, thus estimated as the main hydrocarbon discharge stratum. 主要的认识为:1)本区下白垩统K1ba和K1bt12套成熟烃源岩排烃率可以达到32%25~72%25,是主力排烃层。
- The outcomes of calculation and contrast of observed data show that it has good representativeness on sediment transport and can avoid frequent calculation in deciding sediment discharge. 计算结果与实测资料对比表明，在输沙作用方面，它确实有很好的代表性，且利用它确定输沙量时可避免很多频繁的计算。
