查询词典 runoff

It also simulated to calculate runoff and soil loss in the beginning year of soil and water conservation.

4完成了对延河流域生态服务价值的测算。

This will make sure that water will saturate the root areas and not just runoff down the hill.

这将确保将达到饱和，水根地区，而不只是下山径流。

Runoff and sediment yields are greatly affected by the type of land use.

土地利用类型不同对产流产沙的影响程度不同。

Although both of them are used to drain stormwater out of city,they have different design standards, storm sampling methods,frequency distribution,and calculation methods of runoff.

2种排水系统遵循不同行业规范，采用的暴雨选样方法、设计标准、频率分布模型、设计流量计算方法等各不相同。

It can be concluded that the periodic variation of tidal range and water level has both typical semidiurnal and diurnal and semi-monthly period of tide, and 64.8 d period of river runoff, which indicates that water level of the Zhujiang Delta is controlled by tide and river flow.

不同河段潮差及各分潮波振幅与径流量的大小具有明显的反相关关系，径流量越大，潮差越小，三水站潮差随流量以-0 0002的速度减小，网河区下游河段则减小得较慢。上游径流量越大，因克服径流的阻碍作用而消耗的能量越大，潮汐作用强度迅速减弱，各分潮潮波振幅和潮差沿程减小越快。

The algorithm of co-correction is applied in Digital runoff model and has achieved the desired effect.A new approach proposes several steps filtering correction based on level, discharge, roughness separated, each equation of state presented

水动力模型方面，提出了分离水位、流量、糙率三种变量，分别建立状态方程，实现多步滤波校正的新思路，并完成了初步的理论推导。

In addition, with the progress of runoff scouring, the form of soil erosion changed from sheet erosion to rill erosion.

李勇等(1991)和李勇(1995)通过对黄土高原地区乔灌植被根系与土壤物理性质关系的研究，证

It shows that runoff is closely correlated with the features of individual precipitation, and it is also affected by vegetation within a short period of time. Raindrop erosion, sheet flow erosion and rill erosion on the slope are the main soil erosion patterns; sediment yield occurs mainly in flood season. Human activity and individual precipitation are two important factors that control the soil erosion at a small watershed. Comprehensive management on the slope in a small watershed is an efficient measure of water and soil conservation.

分析表明，小流域的产流方式容易随次降雨条件的变化而变化，植被因素在较小时间尺度内就会影响产流；产沙主要来源于坡面上的溅蚀、片蚀和细沟侵蚀，时间主要集中在汛期；人类活动以及次降雨条件是控制小流域侵蚀产沙的重要因素；在小流域内进行坡面的综合治理是水土保持的有效措施。

Surface erosion occurs mainly in farmland, sparse grassland and woodland, is the rainfall and runoff erosion on the surface is relatively uniform, including the raindrop erosion, sheet erosion and rill erosion .

面蚀主要发生在坡耕地、稀疏牧草地和林地，是降水和径流对地表相对均匀的侵蚀方式，包括雨滴侵蚀、片蚀和细沟侵蚀。

A terrains sloe and direction may be computed relative to a plane though the elevation model points. Slope degrees and direction are useful in simulations of precipitation runoff and in defining drainage areas . The triangle terrain model, which comprises sloping triangular surface, is ideal for simulating terrain surface conditions .

坡面和坡面方向是可以藉由三角形的三个角的座标来计算出来，坡度通常是用度数或者百分比的关系来表达和水平之间的关系，坡度方向度数的表示几乎是从北边开始。

The dissecting of samples in group2 were difficult. The root of pulmonary artery and ascending aorta failed to be unfolded because fibrous tissue was tough, right and left fibrous trigone were too firm to be solved by hand. Cardiac muscle fibers couldn't be stripped along myofibrillar trajectory since they were prone to break because of their friability.

组2的心脏解剖困难，表现为纤维组织坚韧，游离肺动脉非常困难；徒手无法松解左、右纤维三角，肺动脉和主动脉根部的游离非常困难；心肌纤维坚硬、质脆，解剖时容易断离成碎块，无法沿纤维走行方向剥离。

We have battled against the odds in a province that has become increasingly violent.

我们对在一个争夺日益激烈省的可能性。
