In the traditional resistivity sounding method, the poledistance increases little by little with equal logarithm interval, which brings on grid irregular elements.
对于常规的直流电测深法,由于其电极距一般以近似等对数间隔逐渐增大,使得网格单元剖分呈现出不规则性。

Next they had to decide on a "natural" length. They chose one ten-millionth of the distance from the Equator to the North Pole.
接下来他们必须决定一种“自然的”长度,他们选择了从赤道到北极距离的一千万分之一,他们将它称作一米。

I found the distance to our main tent hard enough going, never mind a trek to the North Pole.
