The results show that the original fissure field has characteristics such as the horizontal development of micro-cracks,fissures were fill with filling material,as well as part of the development of vertical cracks,broken.The rock fissures has characteristics such as the intersection cracks in high-angle vertical,and along with reducement of the distance from the roof,gradually development to the broken c...

研究得出原生裂隙场具有绝大多数发育横向微裂隙，裂隙被充填物所充填以及部分发育纵向裂隙，较破碎的特点；采动岩体裂隙则具有发育纵横交错的相交裂缝，以高角度纵向裂缝为主，且随着离煤层顶板距离减小，并逐步向破碎型裂缝发展的特点。

In the interfacial layer near to SiC, elements Pd and Ni preferentially diffused to SiC and resulted in the reaction products of Pd-Si phase, Ni-Si phase and graphite. In the reaction zone further away from the SiC, mainly elements Cr and V in the brazing filler participated in the interface reaction, and formed Cr-C, Cr-Si, Cr5Si3C. In the central part of the joint, the matrix was composed of Pd-Si, Ni-Si and V-Si phases, on which some blocky carbides V2C, Cr23C6 distributed scatteringly.

MPa。微观分析表明，在靠近SiC的界面反应层中，主要是Pd和Ni优先与SiC反应生成相应的Pd-Si相，Ni-Si相和石墨；接头中在离SiC稍远的区域，主要是Cr和V与母材扩散进入钎缝且未与Pd和Ni反应的C和Si发生反应，生成Cr-C， Cr-Si， Cr5Si3C 等相；钎缝中心区的基体由Pd-Si，Ni-Si和V-Si相组成，其上弥散分布着块状碳化物V2C和Cr23C6。

四色海德堡胶印机，如果印版滚筒暗地是涂锌或铁，那么锌或铁城市与水斗溶液边的酸起化学置换不正答生锈、氧化，滚筒体不克不及紧贴衬垫物和印版，如滚筒背恒久泡在酸液边，会爆发腐化生锈，印版滚筒体改成涂铬或镍不离不会爆发以上变乱。

The forming of non- Smithian strata are expounded at theory level.

以殷鸿福等（1998）归纳总结的非威尔逊旋回理论为指导，从理论上阐述了非史密斯地层形成过程：造山带区古大洋相当复杂，尤其是中国古特提斯域古大洋，多为多岛洋，多岛洋是一个宽阔的但不干净的洋，它在其各个演化阶段，始终充满着由裂解地块、裂谷、海道、微板块与次级小洋盆、火山岛弧、海山与边缘海等不同裂离与聚合程度的、海陆相间的多岛洋盆；多岛洋盆在其整个洋陆转化进程中，往往所经历的是多期开合与多期次软碰撞，故由非威尔逊旋回转化而来的造山带混杂岩带地层一般都经历过多期强烈的构造混杂，使造山带演化不同期次、同期次不同阶段、不同大地构造相、不同沉积古地理单元、不同构造层次地层体在极短程内相互拼贴、无序叠置。

After some time, from the initial thalli places to the oil-water interface, the distribution law of microbial concentration was that the concentration increased monotonicly from the minimum to the maximum, that was to say, the nearer to the oil-water interface, the bigger the microbial concentration, and the concentration was the biggest at the interface.

经过一段时间后，从菌体初始位置至油水界面之间的菌浓分布规律为从最小值单调地上升为最高值，亦即离油水界面越近则菌浓越大，油水界面处菌浓最大。

Treatment of spinal tuberculosis1methods between february 1998 and august 2000 , 12 patients with spinal tuberculosis were operated with anterior vertebrectomy , bone grafting and plating1 evaluation including bone fusionrate , correction of deformity and status of spinal lesion was carried out1results in an average of ten months ,spinal tuberculosis was completely cured and solid bone fusion had taken place in all 12 patients1 the time for bone fusion averaged 518 months and the average angle of correction of kyphosis was 16°1conclusions anterior plating following vertebrectomy and bone grafting offers a complete removal of lesion and decompression of the spinal canal as well as reconstruction of spinal stability1 early rehabilitation and an increased curative rate can be expected through this procedure1

目的 探讨经脊柱前路结核病灶清除的同时植骨内固定的可行性和必要性，以及对脊柱结核的治疗效果。方法1998 年2月~2000 年8 月采用脊柱前路病椎切除加植骨，并采用orion或z-plate 钢板进行椎体固定。共治疗12 例脊柱结核，观察植骨融合及矫正畸形情况和结核病灶愈合情况。结果经平均10 个月的随访，12 例患者脊柱结核均治愈，植骨与受骨区全部骨性融合，融合时间平均为518 个月，后凸矫正角度平均16°。全组病例切口均一期愈合。无手术并发症。结论本方法可经脊柱前路作较彻底的病灶清除，并较好地进行脊柱矫形和椎管减压，完成脊柱稳定性重建，有利于患者早期离床活动和脊柱结核治愈率的提高。
