Modification of SiC coating was carried out with B and BC_x prepared by chemical vapor deposition(CVD),SiC/B/SiC and SiC/BC_x/SiC multi-layer self-healing coatings were prepared on a two-dimensional C/SiC composite.
采用化学气相沉积法(CVD)制备单质B和BC_x分别对SiC涂层进行改性,在二维碳纤维增强碳化硅(2D C/SiC)复合材料表面制备SiC/B/SiC和SiC/BC_x/SiC两种多层自愈合涂层,并利用扫描电镜对多层涂层表面和断面进行显微分析。
By analyzing the origin and the growth characteristic of the east inclined synsedimentary fault in Dongpu sag, the combination of the fault and downthrow block fault can be divided into four forms and the oil-gas distribution characteristics in different types of the fault combination are summarized.
分析了东濮凹陷东倾同沉积断层的发育特征及其成因,将该断层及下降盘断层组合概括为四种形式,并总结了不同断层组合中油气的分布特点。
