作物垄作的数学模型

The Models of Geometric Mathematics in the Ridge Culture of Crop

应用高等数学中对面积的曲面积分等方法,建立了垄作种植中半椭圆形、抛物线型和三角形垄的数学模型,比较了不同垄形、垄宽、垄高在增加单位土地表面积和突出地面垄体体积的效果.

Adoption inside of high etc. mathematics curved face integral calculus that accumulate in front etc. method, established the Ridge to make to plant the inside the half the oval, parabola the type with the mathematics model of the triangle Ridge, compare impassability Ridge form, Ridge the breadth, Ridge is high to accumulate in the surface in gain unit land with the result of the physical volume of outstanding ground Ridge.
