The results show that the undissolved silicon particles in the melt become the cores of primary silicon precipitated in solidification and there is a close relationship between the shape of primary silicon and undissolved silicon particles. The growth of silicon follows not only the twin plane re-entrant edge mechanism, but also layer mechanism as well. Meanwhile, the shape of primary silicon also relies on kinetic surroundings, such as the transmitting of solute. At higher overheating temperature, the shape of primary silicon becomes the star-shape and tree-shape.

结果表明：重熔过程中熔体中未溶解的硅相粒子，在凝固过程中可成为初生硅生长核心，并且未熔颗粒与初生硅形状之间存在明显对应关系；初生硅的生长机制不是惟一的，既可以以孪晶凹角机制生长，还可以以层状机制生长，初生硅最终形状还要取决于溶质传输等动力学环境；随着熔体过热温度的升高，凝固组织中初生硅形状由多边形向星形及树枝状转变。

The basic pattern of fairyland excursion combined with the life in seclusion had been created in the works of Sao tifu. The description of immortals in Hanfu was obviously different from the reflection on one's life experience by describing fairyland excursion in Chu Ci. What it pursued was mostly the pure fun in the fairland. The change of fairyland excursion from the heavenly spheres to the human worlds in Hanfu extended the space of artistic imagination of description of immortals. The fairy world in Hanfu was free and beautiful, which had become a symbol of spiritual realm of writers and the reflection of their interest in cloistral area.

汉赋将游仙与退隐相结合，开启了游仙隐逸化的基本表现模式；汉赋的游仙描写，已不完全是&楚辞式&的借游仙以抒怀，更多地表现出了真正意义上的&列仙之趣&；从楚辞到汉赋，游仙遇仙地点发生了由天界向人间的转变，从而进一步拓展了游仙描写的艺术想象空间；汉赋中的神仙世界自由美好，已成为文人精神境界的一种象征，寄托着赋作家遗世高蹈、超乎尘垢之外的人生志趣。
