由于冀东磁铁矿自身的特点，氧首先吸附在颗粒表面的解理缝周围，并与解理缝周围的磁铁矿反应形成针状或片状赤铁矿；然后氧化过程沿磁铁矿的八面体或解理缝继续发展，形成条状或网状结构的赤铁矿，最终完全氧化。

The explicit solution of the strain energy release rate of crack propagation along the pure bend sandwich beam specimen has been deduced in the paper by use of the superposition principle of the energy and section inversion method. Based on the critical load of crack propagation along the interface through the testing measurement, the fracture toughness of four-point bending Si3N4/Al/Si3N4 specimens along Si3N4/Al diffusion joining interface has been obtained by using the explicit solution.

利用能量的叠加原理和截面转换方法，本文导出了纯弯曲Sandwich梁试样界面裂纹扩展应变能释放率的显式解，并根据实验测得的界面裂纹扩展的临界载荷，用其计算出了四点弯曲Si3N4/Al/Si3N4试样Si3N4/Al扩散连接界面的断裂韧度。

断裂起源于轮缘表面的热裂纹，为典型的疲劳断口。

Based on the pennyshaped crack model and the hydraulic fracturing principle,the sand lens reservoir of horizontal occurrence is simplified as a type-I pennyshaped crack of the cap rock. It is due to the fact that the thickness and horizontal distribution length of the reservoir are much smaller than the global cap rock scale. The cap rock fracture resistance of the storage box is analyzed from the view of rock fracture mechanics.

基于币形裂纹模型和水力致裂原理，将纵向厚度和横向展布长度均远小于盖层岩石尺度的水平产状砂岩透镜体简化为盖层岩石中的I型币形裂纹，从岩石断裂力学角度分析封存箱盖层岩石的抗断裂性能。
