Based on the seal mechanism, the sealing conditions of the three migration pathways are analyzed in this paper: the seal on a fault rock zone without adhesive power is dependant on the content of fault mud; the seal of an associated fracture inside a crushed zone is dependant on the relationship between the section pressure and fragile strength of the fault gouge; the seal quality of an induced fracture zone is controlled by the quantity of later rock-forming fill.

基于这种封闭机理，分析了3种通道封闭的条件：无粘结力断层岩带是否封闭取决于断层泥含量大小；破碎带内部伴生裂缝的封闭性取决于断面压力和断层泥塑性强度关系；诱导裂缝带封闭程度受控于后期成岩充填的程度。

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。

Study shows that compaction and cementation can play a destructive role in Suining formation reservoir,while dissolution and fracturing can play a constructive role in that.The main facies of Suining formation are ferruginous-shale film,anhydrite,dolomite and calcite.The micro-fracture and grain-edged fracture mainly resulted from compaction fracturing,compaction slipping and tectonic dynamic force greatly improve the reservoir permeability.

研究表明：①对遂宁组储层起破坏作用的是压实作用、胶结作用和交代作用，而溶蚀作用、压裂作用则对储层起到建设性作用；②遂宁组最主要的成岩相组合为铁泥膜－硬石膏－白云石－方解石成岩相；③由压实破裂、压实滑动和构造动力形成的微裂缝、粒缘缝有效改善了储层的渗透性。

AIM: Different fracture bone defects are established on zygomatic arch of New Zealand rabbits to obtain the critical size fracture defect of the zygomatic arch.

目的：在新西兰白兔颧弓上制备不同的骨折骨缺损，以求得兔颧弓骨折骨缺损植骨临界值。

Temporal bone fracture occasionally occurs, but a pure fracture of tympanic portion of the temporal bone is less common.

颞骨骨折并不罕见，但是单纯的颞骨鼓室部骨折则不常发生。

It is linear elastic until catastrophic fracture, and its fracture is not deterministically predictable.

同时，它的强度和韧性还受限于裂纹和台阶等缺陷的存在，因而对其断裂是无法事先预测的。

The right parietal bone of anesthetized rats was exposed, and bone window of 5 mm was opened 2 mm near median line, then moderate brain injury was made by sap pressure, and the rat models of tibial fracture were established. The fracture group was only subjected to cranial bone window, and the control group was not given any treatment.

实验方法：麻醉后显露大鼠右颅顶骨，中线旁2 mm 处开直径5 mm 骨窗，液压打击致中度脑损伤，并制备大鼠胫骨骨折模型，其中单纯骨折组头部只做颅骨开窗，正常对照组不做任何处理。

This series included 35 male and 22 female, and the mean age was 34.6 years (range, 13– 66 years). The pathology included atlantoaxial instability in 52 patients (os odontoideum in 26 patients, transerse ligament relaxation or disruption in 20, odontoid fracture nonunion in 6), and irreducible atlantoaxial dislocation in 5 (os odontoideum in 1 patient, transerse ligament relaxation in 1, malunion of odontoid process fracture in 3). Twenty-four patients presented signs and symptoms of spinal cord and/or brain-stem dysfunction.

这个系列包括35个男性病人和22个女性病人，平均年龄是34.6岁（范围，13~66岁）。52个病人是寰枢椎不稳（26例os odontoideum、20个横韧带松弛或破裂、6例齿状突骨折不连），5例不可复位的寰枢椎关节脱位（1例os odontoideum，1例横韧带松弛，3例齿状突骨折连接不正）。24例有脊索和脑干功能不良的症状和体征。

The odontoid vertebra space in the model was divided into lattices and the stress area of the odontoid vertebra was identified by force loading and analyses. It was found that the structure of the stress concentration area was closely related to the development of split sections. Therefore,when the odontoid process is attacked by the external force along its vertical plane,its waist is likely to break and type II fracture occurs. And the break also possibly appears in its base,in this way,type HI fracture occurs.

确定其材料性质、单元类型并控制好网格划分精度后，通过力的加载与分析，找出枢椎的结构应力区，根据结构的应力集中区与其断裂时断裂面走向的密切关系，从而判断出当外部载荷沿齿突中性矢状面不同角度作用，即齿突受到来自其矢状面的外部冲击时，容易在齿突腰部发生断裂，形成枢椎齿突Ⅱ型骨折，也可能在基底部发生断裂，形成枢椎齿突Ⅲ型骨折。

I am accused of being overreligious," she said in her quiet, frank manner,"but that does not prevent me thinking the children very cruel who obstinately commit such suicide.""
