摘要以宿南矿区为例，通过对“四含”沉积物沉积前的古地形、沉积物的颗拉大小与磨圆度、物质来源，得出沉积相特徵。 - The oxidations of the joints of c / sic composites after vapor deposition at elevated temperature in air were studied . results showed the joints of composites have good oxidation resistance . after the joints were oxidated at 10001 , the strength of the joints can maintain the original value prior to the vapor deposition
对经气相沉积的c sic复合材料连接在高温空气中的氧化行为进行研究，结果发现气相沉积后复合材料连接有较好的抗氧化性能，在1000氧化后，试样强度与气相沉积前的原始强度相接近。
