Sedimentary rock is the best place to find fossils. 沉積巖是找到化石的最佳地方。
A rounded massof mineral matter found in sedimentary rock. 混凝土發(fā)現于沉積巖中的圓形礦石塊。
The hydraulic effect of the ground water on the preferred planes in consequent rock slope is analyzed in this paper. 本文分析了地下水對順層巖坡優(yōu)勢面水力學(xué)作用的機理。
The superficial rock weathering in slope results in strength abasement and rock creeps are key factors that affect slope stability. 此外，邊坡淺層巖體風(fēng)化導致巖體強度降低，邊坡巖體出現蠕變性也是影響邊坡穩定性的重要因素。
