- Surface gradient sampler
表面梯度采水器 - The bottom slope source terms is treated with surface gradient method so as to obtain the high - order accuracy result in the scheme
采用這種算法并對淺水方程的底坡源項按水面梯度法進行處理，可以獲得較高精度的模擬結(jié)果。 - The experiment data shows that the region with large surface gradients in longitudinal and horizontal direction locates at the vicinity of spur dike . backwater appear upstream the spur dike , and there exist a recirculation area at the same side downstream the spur dike
實測水位資料表明水流縱橫向比降大的區(qū)域位于丁壩上下游附近，在丁壩的上游出現(xiàn)壅水，下游存在有收縮區(qū)和恢復(fù)區(qū)，離丁壩越遠縱橫向水位的變幅越小。 - The outcomes show that cultivation measures have the reduction functions of run - off energy and slope sediment production , of which , the action of contour cropping is the maximum and the action is reduced along with the increase of rainfall intensity and surface gradient ; cultivation measures also have a certain correlation on the reduction functions of run - off energy and erosion , in the meanwhile of slope sediment production , it is effected by the factors of soil erosion resistance and scouring resistance
結(jié)果表明：耕作措施對徑流能量及坡面產(chǎn)沙均具有削減作用，其中等高耕作的作用最大，隨雨強和地面坡度的增大其作用減弱；耕作措施對徑流能量的削減作用與減蝕作用之間具有一定的相關(guān)關(guān)系，但坡面產(chǎn)沙同時受土壤抗蝕、抗沖性等因素的影響。
百科釋義
In vector calculus, the surface gradient is a vector differential operator that is similar to the conventional gradient. The distinction is that the surface gradient takes effect along a surface.
