Because the surface of the water table is not flat but instead rises and falls with topography, groundwater is affected by gravity in the same fashion as surface water.
由于地下水位不是平面的,而是随着地形起伏的,所以地下水和地表水一样受到重力的影响。
These types of equipment are basically comprised of inclined trough separator, oscillating table, spiral separator and centrifugal gravity separator.
这类设备主要包括斜槽分选机、摇床、螺旋分选机和离心重力分选机。
The results for the centre of gravity position and principal axes are presented relative to the surface of the moving table.
重心位置和主轴用相对于运动台表面来表示。
By the way, when I say there's 10 Newtons acting this way, you might say, "What about gravity? What about the table?"
顺便提一下我说有 10 牛的作用力,你也许会问,"那重力呢,桌子对它的力呢"
