1. By the test, the paper draws the conclusion that seam kind, seam width, stitch density and stitch kind have effect on seam strength. 通过实验分析，得出缝型、缝宽、针迹密度及线迹类型等因素对缝口开裂强度的影响。
2. Its main mineable coal seam belongs to very thick coal seam. The coal seam texture and coal rank configuration are generally very complex. 主采煤层属巨厚煤层，其煤层结构和煤种结构一般都很复杂，按不同煤种进行分层开采，有利于煤炭资源合理利用。
3. In appearance, the welt seam is similar to the wrong side of the flat fell seam. join the fabric, right sides together, with seam allowance. 外观上与明包缝的反面相似。将纪念品物的正面合在一起缉缝。
4. The horizontal section top coal caving in steep seam is different from the gently inclined seam. Following the horizon of the coal seam thickness, the working face is arranged with short length. 急斜煤层水平分段放顶煤开采与缓斜煤层不同，工作面沿煤层厚度的水平线布置，长度短。
5. On template building, the initial conditions of seam tracking are put forward, and then a groove or seam template is got according to the pipeline seam recognition initial conditions. 建立模板部分首先确定焊缝跟踪的初始条件，然后根据初始条件在可识别纹理提取结果中获取坡口及焊缝部分模板。
