The glacier incurs stresses due to the change in the bed-rock topography it flows over, the lack of pressure in front of it and the reduction in thickness at the front.

由于它经过的床岩地势变化，以及它的前部缺乏压力，厚度缩小，冰川遭受到压力。

Modelling tests are made in this paper to check the error subtraction scheme of the pressure gradient force in models with topography developed by the authors.

本文则用气候模式对作者提出的有地形数值模式中气压梯度力的误差扣除法进行了模拟检验。
