cleats

Bowsprit Gammoning: Shows the bowsprit cleats, gammon cleats, gammoning knee, gammoning, wooldings, and bowsprit fairlead saddle.

桅夹板，猪腿夹板，猪腿膝关节，猪腿，绞扎绳索，及鞍状的导索器。

The result shows that the cleat density in coal bed varies in different microlithotype,and the occurrence of cleat is relevant to the grouping sequence of microlithotypes.

结果表明,裂隙在微煤岩类型煤体中的分布存在较大的差异,时裂隙分布的位置与微煤岩类型的组合序列有关。

The relationship between microlithotype and the distribution of cleat in coal bed is discussed through a case from Hedong coalfield, combining microstratigraphy and statistics methods.

摘要综合利用微地层学和统计学方法，以河东煤田中北部8＃煤层为例，研究了煤层微煤岩类型与煤层裂隙分布的关系。
