cleat

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

斜桅夹板，腿夹板，腿膝关节，腿，绞扎绳索，及鞍状导索器。

2.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,裂隙在不同显微煤岩煤体中分布存在较大差异,同时裂隙分布位置与显微煤岩组合序列有关。

3.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.

摘要综合利用显微地层学和统计学方法，以河东煤田中北部8＃煤层为例，研究了煤层显微煤岩与煤层裂隙分布关系。
