层裂

Principles of microseismic monitoring in imaging of hydraulic fracturing, monitoring of waterflooding front, and dynamic monitor of reservoir and earth stress were discussed.

重点介绍了在油田中用微地震监测技术进行水力压裂裂缝成像、水驱前缘监测、储层描述和地应力监测的应用原理。

When the fault throw is relatively small, the shale gouge ratio and clay smear potential are relatively large and shale smear is strong. In addition, the coal layers on both sides of the fault are mainly juxtaposed against shale. Therefore, shale smear and juxtaposition play a key role in the sealing. In contrast, when the fault throw is relatively large and shale smear is relatively weak, juxtaposition is unfavorable for sealing. However, the mylonite resulted from strong cataclasis can act as a seal of the coals. The cementation resulted from underground water activity is of great significance to the sealing ability of the fault. Mylonitic coal layers resulted from faulting occur on both sides of the fault. They are unique reservoirs with low permeability and high displacement pressure and their scales depend, to some extent, on the fault throw, fault properties, the hanging wall and footwall.

结果表明：①当断层落差较小时，断层泥比率和泥岩涂抹潜势值较大，泥岩涂抹效应强烈，且与断层两侧煤层对接的岩石主要为泥岩类，此时起封闭作用的主要为泥岩涂抹作用和断层两侧岩性配置关系；②当断层落差较大，泥岩涂抹作用较弱时，对接越不利于封闭形成，但碎裂作用强烈，沿断层两侧形成的糜棱岩对煤层起到了封闭作用；③地下水活动导致的胶结作用对整个断层的封闭具有重要的意义；④断裂作用形成的糜棱煤沿断层两侧分布，此糜棱煤带是一种低渗透、高排替压力的特殊储层，其规模与断层的落差、性质、上下盘都有一定关系。

Among the macroporous resin fractions of 30%, 50%, 70%, 80% and 95% ethanol, the 70% ethanol fraction showed the highest antifungal activity towards Schizosaccharomyces pombe and Candida albicans.

在30%，50%，70%，80%，95%乙醇溶液的大孔树脂柱层析洗脱组分中，70%乙醇溶液洗脱组分对裂殖酵母菌和白色念珠菌的抗真菌活性最强。

Objective: To discuss the method of scanning and image reconstructin with MSCT in lumbar spondyloschisis.

目的：探讨多层螺旋CT在腰椎峡部裂诊断中的扫描及重建方式。

But where there are brittlement intermetallics segregating in pre-eutectic phase , the non-eutectic phase maybe make the coating crack more susceptibly because of their resistance to dislocation moving.

在多道搭接熔覆时，搭接区结晶方向与激光扫描方向的夹角越小，越有利于提高熔覆层的抗裂性。

The matrix of the work layer of such kind of roll contains evenly-distributed graphite in the state of pellets, balls, vermes or sheets besides carb ides and ledeburite. Therefore, this material has not only better resistance to wear, but also better properties of resistance to spalling and fire crack.

由于该类轧辊工作层基体组织内除含有碳化物和莱氏体外，还存在均匀分布的球状、团状、蠕虫状或片状石墨，正因如此，除自身具有较好的耐磨性外，还具有较好的抗剥落性、抗热裂性。

During construction, vacuum chuting, induced joints, consolidation grouting with and without cover weight, improved concrete, high anti-cracking materials and other quality control methods were used.

But he could still end up breakfasting on Swiss-government issue muesli because all six are accused of nicking around 45 million pounds they should have paid to FIFA.

不过他最后仍有可能沦为瑞士政府&议事餐桌&上的一道早餐，因为这所有六个人都被指控把本应支付给国际足联的大约4500万英镑骗了个精光。
