This pattern is consistent with the passing of a cold weather front bearing a strong area of low pressure at the surface.
沙尘暴的这种分布型式与地面冷锋造成的强低压区相一致。

In this paper the influence of wheel unbalance on the ground surface roughness is investigated in consideration of the disadvantages of dynamic pressurebearing.
本文从分析动压轴承的弱点出发,着重就砂轮不平衡量对磨削表面粗糙度的影响作了探讨。
