We had used height anomaly to solve the mixed boundary value problem by measuring the value of gravity of standpoint, level coordinate and height.
传统的作业方法是通过测量地球表面固定点的重力值、水平坐标和高程得到重力异常来求解混合边值问题。
The wall of the house starts as a site boundary. It draws a continuous spiral and ends as the partition of a central single room, gradually changing its height.
房子的墙沿地块边界而建，连续地盘旋环绕，墙体高度不断变化，并在房子中央围合出一间单人房。
When the relative gap height (the ratio of flap height to gap width) is in the range of 0 8-2 0, the mean pressure will reduced 30% if the flap height is smaller than the thickness of boundary layer.
