Under the condition of the same time interval the fracture toughness of the specimens with treated layer surfaces is higher than that of untreated.
层面间隔时间相同的情况下，层面经过处理的试件要比层面不处理的试件的失稳韧度大；
2
Severity of fracture, interval between injury and surgery, and skills of orthopedists determine the clinical outcome, operation duration, and perioperative blood loss.
临床结果、手术耗时和术中失血不仅与骨折程度和损伤至手术的时间有关，而且与手术医生的经验有关。

Through the analysis and acquisition of the seismic interval velocity, This paper has comprehensively studied and evaluated fracture pressure prediction method for the typical formations.
