These sections, via repetitive loading, are subject to microfractures that are not reliably repaired, and which can result in catastrophic failure of the graft.
这部分不断修复，常有未可靠修复的微裂缝，可导致移植的重大失败。
2
The factors which influence the microfractures are the structural position, compositional maturity, grain size, the quantity of cements as well as specific compaction.
影响构造微裂缝发育的因素是：所处的构造应力部位，岩石成分成熟度、粒度、压实程度和早期填隙物含量。

The types, characteristics, ages and parameters of the microfractures in T3x2 of Qiongxi structure are studied through microscopic thin section analysis and in combination with core and outcrop data.
