目的  提高人体（动物）管道铸型标本水晶包埋制作成功率，以更好地长期保存和应用铸型标本。   方法  通过对包埋模具选择，标本固定，配胶比例调整及打磨抛光等工序改进，以制作 1 例胎肺管道铸型标本水晶包埋模型为实践，探讨优化一条水晶包埋人体(动物)管道铸型标本简便高效制作方法。   结果  改良后制作水晶模型透明度高，造型精细美观，无气泡产生，无铸型支断落。水晶模型可以通过不同平面以任意角度、任意方位清晰地观察到包埋中胎肺铸型支分布及其走行情况，与包埋前铸型标本相一致，立体空间感较强。   结论  改良后工艺制作包埋人体（动物）管道铸型标本更优，利于长期保存，更好应用于临床解剖示教和生命科学馆展示。

Objective  To improve the success rate of crystal embedding of human (animal) pipeline cast specimens for long-term preservation and application of cast specimens better.    Methods  The selection of embedding mold, specimen fixation, adjustment of the proportion of glue, grinding and polishing were improved, and a crystal embedding model of a fetal lung duct cast specimen was made to explore and optimize the simple and efficient production process of a crystal-embedded human (animal) pipeline casting specimen.    Results  The crystal model produced after the improvement had great transparency, beautiful shape, no bubbles, and no mold branches broken. The distribution and running of the casted branches of the fetal lung of the crystal model could be observed clearly in the embedded middle fetal lung through any angle and orientation, which was consistent with the cast specimens before embedding, and had a strong sense of three-dimensional space.  Conclusion  The improved process is better for embedding human (animal) pipeline casting specimens, which is conducive to long-term preservation. It is better for clinical anatomy teaching and exhibition in life science museum.
