This is not linear step-by-step progress, the boulder gradually nudged up the slope, but progress characterized by huge leaps and bounds forward.

这种进展不是以直线形式逐步取得的，不是将巨石缓缓推上斜坡，而是以巨大飞跃和大跨步前进为特点的进展。

Combining the actual project example, non-linear FEM is used for a stability analysis of high slope and a way of judging the slope stability is put forward for reference.

结合工程实例用非线性有限单元法对高边坡进行稳定分析，并提出判断边坡稳定的方法，以供参考。

I was moving forward over a slope that seemed safe when suddenly without warning my world dropped out from under my skis.

我正在一个似乎安全的斜坡上往前走，突然间毫无预兆，滑雪板下的大地陷下去了。

This means that when the vehicles come across a particularly steep or slippery slope, they can anchor themselves with five of the wheels and inch each wheel forward one at a time, to crawl over an obstacle.
