After the structure was optimized, the intensity utilization coefficient of horizontally side-post, arch steel tube and mid-post increased 18%, 3%and 25%respectively, the vertically side-post which was utilized insecurely and insatiably utilized securely, stably, and reasonably, and steel of main body was saved about 3.7%.

优化设计后的连栋塑料温室，其横边柱、拱架和中柱的强度利用率分别提高了18%、3%和 25%，纵边柱由非安全失稳利用转向稳定安全性合理利用，主体结构节省钢材3.7%。

Surrounding the central cylinder is the pericycle.

围绕中柱的是中柱鞘。

Pericycle The parenchymatous layer of cells that lies within the endodermis,forming the outermost part of the stele.

中柱鞘：位于内皮层以内紧挨内皮层的一层或几层薄壁细胞，形成中柱的最外部分。

Short-segment instrumentation with transpedicular intracorporeal grafting in the treatment of thoracolumbar burst fracture can reconstruct the stability of anterior and middle column and effctively prevent the loss of correction.

结论短节段椎弓根螺钉固定和经椎弓根椎体内植骨治疗胸腰椎骨折，可重建前、中柱的稳定性，有效防止纠正度的丢失。

In functional study, overexpression assay was conducted in potato. Interestingly, tuberous swelling along roots was observed in some transgenic potato lines in addition to stem-derived tuber formation. Conclusively, we propose a hypothesis to illustrate the mechanism by which IbMADS1 participates in the initiation of tuberization in sweet potato.

利用解剖切片观察并比较转殖马铃薯与野生型甘薯的根部块状膨大区域，可以发现两者在膨大初期，中柱内含的细胞数皆增多，尤其是木质部细胞出现不正常增生情形，进而扩展中柱区域；因此，我们可以初步推论在甘薯块根发育初期，IbMADS1藉著作用於根部分生组织，尤其是中柱的原始形成层，从而促进细胞分裂，并参与甘薯的初期结薯。
