Gentle and steep
窈峭───Gentle and steep
Your sled starts moving sooner and moves faster on a steep hill than on a gentle slope.───你的雪橇在陡峭的山上,比在平缓的山坡上滑动得更快。
Sand is blown up the gentle slopes and falls down the steep lee side of the dunes.───沙粒被吹至缓坡,沿沙丘陡峭的背风面滑落。
gentle and, like drainages, the routes often go under or over barriers such as highways, creeks, steep hills or other obstructions.───类似下水管道,铁路线的坡度平缓,经常从地下穿过或从高空越过高速公路、溪流、险山和其他障碍物。
