karstification is mainly the chemical corrosion of water to soluble rocks, and also includes the mechanical erosion and the collapse as well as moving out, transporting and redepositing of matter.
the results show that the ablation process of c/c composites is controlled by chemical erosion and mechanical erosion and mainly by mechanical erosion.
结果表明:c/c复合材料的烧蚀由化学烧蚀和机械剥蚀共同控制,以机械剥蚀为主;
wind, water, chemical, and mechanical erosion shaped the granite into their distinctive shapes, revered by aborigines as the eggs of the rainbow serpent.
