tail surface 中文意思是什麼
tail surface
解釋
尾面-
It was specially pointed out that, when the tail water is constant maximum tide, the computed flood surface is higher than that of nonsteady current, so there is some safety superelevation. underestimation of the roughness will make downward bias to compute along - river surface and bring hidden trouble for flood control. to improve the section can decrease the water level or offset the water rise for increase of floodplains " roughness, but it need much engineering works
特別提出，按照恆定流計算出來的設計水位比非恆定水位具有一定的安全儲備；而對于灘地糙率的低估又會造成設計水位的偏低，給防洪工作帶來隱患；如果利用改進斷面形式來降低水位或彌補糙率增加帶來的水位抬高，需要較大的工程量，所以平時應注意灘面的減糙管理工作。 -

It can be used not only to infer position of the magnetic body relative to the drill hole but also to make quantitative - semi - quantitative calculation and inverse interpretation and calculation of the distance and depth from head or tail of ore bodies to the known drill hole at surface by rotating an angle so as to design drilling depth, dip angle and orientation of the next drill hole
其作用不僅可以判斷磁性體相對于鉆孔的位置，而且可以進行定量和半定量計算，以及經旋轉一角度採用地面方法作反演解釋，計算礦體頭部或尾部距已知鉆孔的距離、深度，設計下一鉆孔的深度、頂角、方位角。
