Primary study on the histology of exoskeleton of female pleopod in Eriocheir sinensis ;

黏液腺在胚胎附着过程中形成卵柄和外层卵膜，胚胎是依靠卵柄或卵索附着于腹肢的刚毛上，进而完成胚胎发育过程。

Embryo attachment was affected by the differentiation of egg membrane . Egg stalk and outer egg membrane were formed from mucus during development .

用显微及亚显微方法研究了中华绒螯蟹雌体不同生理阶段（幼蟹、未成熟蟹、成熟蟹、抱卵蟹和流产蟹）腹肢的体壁结构变化和粘液腺发育特征。

The tegument and exoskeleton structure and the cement glands activities of female pleopod in different physiological stages of Eriocheir sinensis were investigated by histological method .

胚胎附着系统的形成与雌蟹的行为、腹肢粘液腺分泌的粘液、卵膜的超微结构及各层的变化有关。

The time sequencing of formation of the embryo attachment system is determined by the behavior of females , the activities of cement glands as well as changes of egg membrane ultrastructure .

结果表明，胚胎附着与母体腹肢的结构、黏液腺分泌的黏液相关，也与胚胎表面结构、次级卵膜的形态和结构密切相关。

The results showed that embryo attachment have relevance to not only structure of pleopods , mucus that mucus gland excretive , but also characteristics embryo surface , morphology and structure of the secondary membrane .
