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。

Objective:This paper proposes an iterative noncentral procedure for the sample size determination in log rank test and compares it with the LachinFoulkes procedure. Methods: Samplings are performed with a prescribed size.

The results show that all aluminum anodizing sludges were slightly neutral to acidic and mainly consist of more than 50% Al2O3; the similar total contents of Cu, Pb, Zn, Ni, Cd, and Cr in the 7 samples were found, namely, the concentrations of Pb, Cd were relatively lower, but that of Cu, Zn, Ni, and Cr were higher; the leaching tests indicate that all the samples were classed as nonhazardous wastes; but each of metals in the sample shows very different leaching behavior, possibly depending on their total contents and the final pH of leachates.

结果表明,铝型材污泥属于中性偏酸性物质,主要由Al2O3组成,含量在50%以上。各试样中Cu、Pb、Zn、Ni、Cd及Cr的总含量的分布趋势基本是一致的,其中Pb、Cd的含量较低,Cu、Zn、Ni及 Cr的含量较高。浸出毒性试验表明铝型材污泥属于非危险废物,但污泥中各重金属的浸出特性又各自不同,可能主要与它们在试样中的总含量和浸出液的最终pH值有关。

Results: Among the 1699 subjects included in the efficacy analysis, NXY-059 significantly improved the overall distribution of scores on the modified Rankin scale, as compared with placebo (P = 0.038 by the Cochran-Mantel-Haenszel test). The common odds ratio for improvement across all categories of the scale was 1.20 (95 percent confidence interval, 1.01 to 1.42). Mortality and rates of serious and nonserious adverse events were each similar in the two groups.
