concave slope

The data also demonstrate that concave slope is more pro runoff production and soil erosion than other slope shapes ( convex, S, linear) under grassland ( alfalfa) conditions.

对于草地（紫花苜蓿）类型，凹坡相对于其它坡型（凸坡，S型，直线坡）最容易产生径流和侵蚀。

That is to say, the concave slope is the most stable, the horizontal slope is the second and the convex slope is the worst.

即在坡度一样的情况下，凹坡最稳定，平坡次之，凸坡稳定性最差。

Comparison of the four kinds of slope indicates that the concave slope type is the best oil-bearing one.

通过对4种斜坡的类比表明：凹坡型为最佳含油斜坡。

Propagation of internal waves over linear slope, convex slope and concave slope are discussed by using of the transforms introduced in this dissertation.

利用提出的变换讨论了内波在线性斜坡地形、凸地形和凹地形上的传播特征，分析了入射波能通量在不同模态上的重新分布。

Design of belt conveyor for concave slope variable turn

凹变坡转弯带式输送机的设计

Finally get the following conclusions: ① Compared with planar sloped and concave slope, the toppling deformation of convex slope is easier to happen.

分析结果可以得到：①较之凹形坡与平形坡，凸形坡更有利于斜坡的倾倒变形破坏。

The next wave would lift those objects up to its steep concave slope.
