Szechuanensis had mesophyte characteristics which were different across elevations; these differences contributed to their adaptation to a range of drought environment; the leaf thickness, vein thickness, vessel number, palisade mesophyll thickness and the P/S ratio were increased, while vessel diameter was reduced with increasing elevation, but no significant differences in epidermal thickness and spongy mesophyll thickness were found along the elevations.

随着海拔的升高，叶总厚度、栅栏组织厚度、P/S值和主脉厚度以及导管分子数目等均呈增大趋势，而导管分子直径减小；表皮厚度、海绵组织厚度等无明显差异。2多元统计分析显示，叶肉组织厚度和叶片总厚度主要受温和度的影响，并随着温和度的降低而增大；P/S值和导管分子数目主要与年降水量和土壤含水量的变化有关，随着水分增加，P/S值和导管分子数目增大，而导管分子直径减小。

Results:①The center of the homogeneous density soft tissue masses (mean CT value was 50HU) were located in the middle and lower tympanum,and the external auditory canal or the pharyngotympanic tube was involved in the earlier period;②the destructed b...

结果：中耳癌的CT特征：①表现为以中、下鼓室为中心的软组织密度灶，密度均匀，CT值50HU左右，外耳道及咽鼓管早期受累；②呈溶骨性骨质破坏，形态不规则，边缘无骨硬化表现，外耳道后壁破坏较前壁严重；③病灶侵入颞叶，形成肿块，灶周脑水肿不明显；④增强扫描见病灶有中度强化。结论：CT能确定中耳癌的存在及精确显示肿瘤累及范围。

The leaf epidermis structures of 6 species of Rhododendron had been observed under LM and SEM. The results show that all share together common features as follows: the leaf blades are typical back-abdomen bifacial types, the upper epidermis are formed by two or three layer bigger cells which inside layer cell is bigger than outside one, and the upper epidermis are covered with thicker cuticle.

利用光学显微镜和扫描电子显微镜观察了6种杜鹃属植物的叶片结构，结果表明，它们具有共同形态结构特征：典型的异面叶，上表皮由2~3层细胞组成，内大外小或内、外等大，有较厚的角质膜，无气孔器分布；下表皮均由1层细胞组成，排列紧密；栅栏组织由2层以上长柱形细胞组成，排列紧密；海绵组织细胞较短，排列较疏松，细胞间隙较大；均有表皮附属物。
