Slope (or gradient)
The ratio of vertical height (H) to horizontal width (L) of a slope is called slope (or slope ratio). If the slope angle is α and the slope is k, then k=h:l=tanα, and the slope is generally written in the form of 1: K, where k is called the slope coefficient. The greater the slope, the steeper the slope angle, such as 1: 2 > 1: 3, then: 65438+.
base of slope
The included angle between the slope and the horizontal plane is called the slope angle, which is denoted as α.

The ridge cultivated in freshwater ponds is the contour basis of ponds, and the structure of the ridge has great influence on maintaining the shape of ponds, facilitating production and improving the breeding effect. Pond ridges are generally composed of homogeneous soil, and the top width of the ridges should meet the needs of netting and transportation, generally between 1.5 ~ 4.5 meters. The slope of the pond bank depends on the soil quality, depth, slope protection and culture method of the pond. Generally, the slope ratio of a pond is 1: 1.5 ~ 3. If the pond soil is heavy loam or clay, the slope ratio can be adjusted appropriately according to the soil condition and slope protection technology. When the pond is shallow, the slope ratio can be 1: 1 ~ 1.5. Fig. 4 shows a schematic diagram of the slope. There are also applications of reservoir dams in mathematics, generally speaking, it is the slope rate, and then the cross-sectional area and perimeter of the dam are calculated. There is also a lesson about children climbing stairs, telling you the slope, and finally using Pythagorean theorem to find the length of stairs.
